`asMaps[]`	Object	From v1.1. The AS map configured for the property.
`cidrMaps`	Array	The set of CIDR maps assigned to this domain.
`cidrMaps[]`	Object	The CIDR map configured for the property.
`cnameCoalescingEnabled`	Boolean	From v1.1. If enabled, GTM collapses CNAME redirections in DNS answers when it knows the target of the CNAME. The default value is `false`.
`datacenters`	Array	The set of data centers assigned to this domain.
`datacenters[]`	Object	The data centers in the GTM domain.
`defaultErrorPenalty`	Integer	Specifies the download penalty score. If the download encounters an error, the web agent computes a score that's either the download time in seconds or a penalty score. The default penalty is `75`.
`defaultSslClientCertificate`	String	Specifies an optional Base64-encoded certificate that corresponds with the private key for TLS-based liveness tests (HTTPS, SMTPS, POPS, and TCPS). When the liveness test doesn't contain `sslClientCertificate` and `sslClientPrivateKey` values, use this and the `defaultSslClientPrivateKey` object members to generate a certificate. In this case, use a separate, throwaway private key when generating a certificate or certificate signing request (CSR). You shouldn't use this key for any other purpose. See also `defaultSslClientPrivateKey` within this object.
`defaultSslClientPrivateKey`	String	Specifies an optional Base64-encoded private key that corresponds with the TLS certificate for TLS-based liveness tests (HTTPS, SMTPS, POPS, and TCPS). See also `defaultSslClientCertificate` within this object.
`defaultTimeoutPenalty`	Integer	Specifies the timeout penalty score. The web agent then computes a score that's either the download time in seconds or a penalty score if the download request times out. The default penalty for a time out is `25`.
`deleteRequestId`	String	Unique identifier of the request to delete the domain. This ID can be used to track the status or audit the deletion process.

`loadFeedback`	Boolean	Indicates whether you're using `resources` to control load balancing. Resources represent a constraint on how much load a data center can absorb. The value is `true` if you're using load feedback.
`loadImbalancePercentage`	Number	Indicates the percent of load imbalance factor (LIF) for the domain. It lets GTM exceed the value configured for traffic distribution. For example, if the data center's traffic allocation is 25 percent and the LIF is 1.5, the demand can grow to 37.5 percent (25% × 1.5) before the load balancer starts shifting load away from it. If the LIF is `0`, no load imbalance is allowed. However, internally, GTM adds one to the LIF to allow its use as a multiplier. The default LIF is 1.1, which is displayed as `10.0` percent. The value ranges from `0` to `1000000` percent.

`scorePenalty`	Integer	From v1.3. Influences the score for a data center. Giving a positive penalty increases the score and drives traffic away from the data center. Giving a negative penalty reduces the score and draws in more traffic that would otherwise go elsewhere. As the score is measured in milliseconds of ping time, very small numbers like 1 or 2 have virtually no effect. Typically, penalties are given in the tens or hundreds. Note that `scorePenalty` applies only for properties that use performance load balancing.
`stateOrProvince`	String	Specifies a two-letter ISO 3166 country code for the state or province where the data center is located.
`virtual`	Boolean	Indicates whether or not the data center is `virtual` or physical, the latter meaning the data center has an Akamai Network Agent installed, and its physical location in latitude and longitude is fixed. Either `true` if `virtual` or `false` if physical.
`Domain.datacenters[].defaultLoadObject`
`loadObject`	String	Specifies the load object that GTM requests. A load object is a file that provides real-time information about the current load, maximum allowable load, and target load on each resource. The value cannot begin with a `:` character, and is limited to a maximum of 256 characters.
`loadObjectPort`	Integer	Specifies the TCP port to connect to when requesting the load object. A value of `0` means to use the default port, equivalent to either `80` or `443`.
`loadServers`	Array	Specifies a list of servers to request the load object from. The value needs to contain IPv4 or IPv6 addresses, or DNS names that contain A or AAAA records. If a DNS name has both A and AAAA records, then GTM picks one randomly. For IP addresses, don't use non-routable RFC 1918 addresses.

`href`	String	Provides a hypermedia link to the complete URL that uniquely defines a resource.
`rel`	String	Indicates the link relationship of the object.
`Domain.properties[]`
`backupCName`	String	Specifies a `backupCName`. If GTM declares that all of the servers configured for your property are down, and you configured a `backupCName`, then queries for the property return the `backupCName`. If a `backupCName` is set, don't set a `backupIp`.
`backupIp`	String	Specifies a backup IP. When GTM declares that all of the targets are down, it hands out the `backupIP`. The IP type coincides with the property's `iPv6` setting. If a `backupIp` is set, don't set a `backupCName`.
`balanceByDownloadScore`	Boolean	Indicates whether download score based load balancing is enabled. GTM estimates the load on your data centers based on how long they take to respond to GTM liveness tests. The advantage: you don't need to implement a load object. The disadvantage: it's a very crude measure of load, and usually highly nonlinear. As load increases, download times don't increase significantly, until there's too much load. When that happens, the download times skyrocket. This can easily cause erratic load balancing or load oscillations.
`cname`	String	Indicates the fully qualified name aliased to a particular property. The public name of the property.
`comments`	String	Provides information about the purpose of the property.
`dynamicTTL`	Integer	Indicates the TTL in seconds for records that might change dynamically based on liveness and load balancing such as A and AAAA records, and CNAMEs. The value ranges from `30` to `3600` and can change on request. The default is `60`.
`failbackDelay`	Integer	Specifies the failback delay in seconds. The minimum value is `0`. If specified, when a server has been down and comes back up, (that is, its liveness test starts succeeding again), GTM only considers it up after the failback delay has elapsed and tests continue to succeed.
`failoverDelay`	Integer	Specifies the failover delay in seconds. The minimum value is `0`. If specified, when a server begins failing its liveness test, GTM only considers it down after the failover delay has elapsed and the errors persist.
`ghostDemandReporting`	Boolean	From v1.3. Enables reporting of unmet content requests received by edge servers, analyzing demand for unserved content.
`handoutLimit`	Integer	From v1.3. Indicates the limit for the number of live IPs handed out to a DNS request. The `handoutLimit` applies only if `handoutMode` is set to either `normal` or `persistent` for the property. If applicable, the `handoutLimit` default value is `8` or `null` if not.
`handoutMode`	String	Specifies how IPs are returned when more than one IP is alive and available. Either `normal`, `persistent`, `one-ip`, `one-ip-hashed`, or `all-live-ips`. The default is `normal`. Handout mode is relevant only when you have more than one server IP in a data center.
`healthMax`	Number	Defines the absolute limit beyond which IPs are declared unhealthy. If backup CNAMEs are provided for a property, then it's reasonable for all IPs to be declared unhealthy. The `healthMax` value is multiplied by the smaller of the `timeoutPenalty` and the `errorPenalty`. This check declares as down any server with a score greater than this product. The default value is `null`.
`healthMultiplier`	Number	Configures a cutoff value that's computed from the median scores. Any server with a score over the cutoff value is considered down, and load isn't sent to it. The cutoff is computed from the minimum score across all data centers, for a given property and two object members: `healthMultiplier` and `healthThreshold`. The cutoff is either `healthMultiplier` (default value: 1.5) times the minimum score, or the `healthThreshold` (default value: 4), whichever is greater. See also `healthThreshold` within this object. For more information on how to determine server liveness, see the Global Traffic Management User Guide.
`healthThreshold`	Number	Configures a cutoff value that's computed from the median scores. Any server with a score over the cutoff value is considered down, and load isn't sent to it. See also `healthMultiplier` within this object. For more information on how to determine server liveness, see the Global Traffic Management User Guide.
`ipv6`	Boolean	Indicates the type of IP address handed out by a property. A `true` value indicates that all IP addresses specified are IPv6, and all hostnames need to resolve to AAAA records. A `false` value indicates IPv4 addresses, and all hostnames need to resolve to A records.
`lastModified`	String	An ISO 8601 timestamp that indicates when the property was last changed.
`links`	Array	A URL path that allows direct navigation to the property.
`links[]`	Object	Lists navigable URLs to resources.
`livenessTests`	Array	Liveness tests, which run periodically to determine whether your servers respond to requests, as discussed in API concepts.
`livenessTests[]`	Object	Liveness tests, which run periodically to determine whether your servers respond to requests, as discussed in API concepts.
`loadImbalancePercentage`	Number	Indicates the percent of load imbalance factor (LIF) for the domain. It lets GTM exceed the value configured for traffic distribution. For example, if the data center's traffic allocation is 25 percent and the LIF is 1.5, the demand can grow to 37.5 percent (25% × 1.5) before the load balancer starts shifting load away from it. If the LIF is `0`, no load imbalance is allowed. However, internally, GTM adds one to the LIF to allow its use as a multiplier. The default LIF is 1.1, which is displayed as `10.0` percent. The value ranges from `0` to `1000000` percent.
`mapName`	String	A descriptive label for a geographic map or a CIDR map that's required if the property is either `geographic` or `cidrmapping`, in which case `mapName` needs to reference either an existing geographic map or CIDR map in the same domain.
`maxUnreachablePenalty`	Number	For `performance` domains, this specifies a penalty value that's added to liveness test scores when data centers show an aggregated loss fraction higher than the penalty value. The penalty value is either `maxUnreachablePenalty` (minimum value is `0` and the default is `null`) or `unreachableThreshold` (decimal between `0` and `1`. A value of 1.0 or `null` disables an unreachable penalty). See also `unreachableThreshold` within this object.
`minLiveFraction`	Number	From v1.3. Specifies what fraction of the servers need to respond to requests so GTM considers the data center up and able to receive traffic. For example, if your data center contains eight servers, and the `minLiveFraction` value is `0.5`, then at least four servers need to respond to requests. Conversely, if five servers are down, and three servers are up, then GTM considers the entire data center down. Optional when a `minLiveFraction` value exists or not `null`.
`mxRecords`	Array	Specifies the MX records handed out to `MX` record type queries. Note that mapping and liveness testing aren't done. The same MX records are handed out for every request.
`mxRecords[]`	Object	The object that contains maximum number of records.
`name{Hostname}`	String	The hostname.
`name{apex}`	String	The APEX name.
`scoreAggregationType`	String	Specifies how GTM aggregates liveness test scores across different tests, when multiple tests are configured. Values are `mean`, `median`, `best`, or the default `worst`.

The value ranges from `0` to `30000`. See also `stickinessBonusPercentage` within this object. To learn more about how these object members relate to each other, see API concepts.
`stickinessBonusPercentage`	Integer	Specifies a percentage used to configure data center affinity. This only applies if the property `type` is `performance` and the domain `type` is `full`. The value ranges from `0` to `100`. See also `stickinessBonusConstant` within this object. To learn more about how these object members relate to each other, see API concepts.
`trafficTargets`	Array	This specifies where to direct data center traffic. For geographic mapped properties, it's always a `cname`. For mirror failover properties, it can be any set of servers. For load balanced properties, this is a set of servers that are all within the same data center. You can assign multiple traffic targets to the same data center.
`trafficTargets[]`	Object	This specifies where to direct data center traffic. For geographic mapped properties, it's always a `cname`. For mirror failover properties, it can be any set of servers. For load balanced properties, this is a set of servers that are all within the same data center. You can assign multiple traffic targets to the same data center.
`type`	String	Specifies the load balancing behavior for the property. Either `failover`, `geographic`, `cidrmapping`, `weighted-round-robin`, `weighted-hashed`, `weighted-round-robin-load-feedback`, `qtr`, `performance`, `performance-with-load-feedback`, `asmapping`, `static`, or `ranked-failover`. See API versioning for more information.
`unreachableThreshold`	Number	For `performance` domains, this specifies a penalty value that's added to liveness test scores when data centers have an aggregated loss fraction higher than this value. The value is a decimal between `0` and `1`. A value of `1.0` or `null` disables an unreachable penalty. See also `maxUnreachablePenalty` within this object.
`useComputedTargets`	Boolean	For `load-feedback` domains only, this specifies that you want GTM to automatically compute target load. Report only the current load objects, either by omission, or by using non-XML load objects.

`disableNonstandardPortWarning`	Boolean	Disables warnings when non-standard ports are used. For example, GTM doesn't emit a warning to specify port 1234 when the `testObjectProtocol` is `http`, as HTTP typically uses port 80. The default is `false`.
`disabled`	Boolean	From v1.4. Disables the liveness test. When disabled, GTM stops running the test, treating it as if it no longer exists. The default is `false`.
`errorPenalty`	Number	From v1.2. Specifies the score that's reported if the liveness test encounters an error other than timeout, such as connection refused, and 404. The default value is `75`.
`hostHeader`	String	Sent if the `testObjectProtocol` is `http` or `https`, up to 256 non-space, alphanumeric characters. Obsolete as of version 1.4. You should use `hostHeaders` instead.

`aggregationType`	String	Specifies how GTM handles different load numbers when multiple load servers are used for a data center or property. Either `sum`, `median`, or `latest`. For test time load feedback, consider `median`. (Akamai conducts tests from multiple locations, so you can ignore outlying values.) For load feedback with manual targets or dynamic targets, consider `latest` because all load servers normally report similar numbers.
`constrainedProperty`	String	Specifies the name of the property that this resource constrains, or `**` to constrain all properties.
`decayRate`	Number	For internal use only. Unless Akamai indicates otherwise, omit the value or set it to `null`.
`description`	String	A descriptive note to help you track what the resource constrains. For example, `aggregate bandwidth for all properties`. A maximum of 256 characters.
`hostHeader`	String	Optionally specifies the host header used when fetching the load object.
`leaderString`	String	Specifies the text that comes before the `loadObject`. GTM assumes that the current load is the first number to appear after this text, minus any white space. The value is a maximum of 256 characters. The default is `null`. For example, suppose your `loadObject` file contains, This is a load object. TheLoadIs:497. This is the end of the load object. Then GTM reads the current load as 497 if the `leaderString` is set to TheLoadIs.
`leastSquaresDecay`	Number	For internal use only. Unless Akamai indicates otherwise, omit the value or set it to `null`.
`links`	Array	Specifies the URL path that allows direct navigation to the resource.
`links[]`	Object	Lists navigable URLs to resources.
`loadImbalancePercentage`	Number	Indicates the percent of load imbalance factor (LIF) for the domain. It lets GTM exceed the value configured for traffic distribution. For example, if the data center's traffic allocation is 25 percent and the LIF is 1.5, the demand can grow to 37.5 percent (25% × 1.5) before the load balancer starts shifting load away from it. If the LIF is `0`, no load imbalance is allowed. However, internally, GTM adds one to the LIF to allow its use as a multiplier. The default LIF is 1.1, which is displayed as `10.0` percent. The value ranges from `0` to `1000000` percent.
`maxUMultiplicativeIncrement`	Number	For internal use only. Unless Akamai indicates otherwise, omit the value or set it to `null`.
`name`	String	A descriptive label for the resource. A maximum 150 non-space characters.
`resourceInstances`	Array	The `resources` that constrain the `properties` within the data center.
`resourceInstances[]`	Object	TBD.
`type`	String	Indicates the kind of `loadObject` format used to determine the load on the resource. Either `XML load object via HTTP`, `XML load object via HTTPS`, `Non-XML load object via HTTP`, `Non-XML load object via HTTPS`, `Download score`, or `Push API`.
`upperBound`	Integer	An optional sanity check that specifies the maximum allowed value for any component of the load object. If the `loadObject` contains a number that exceeds this value, it rejects the entire load object as invalid and GTM continues to use the load values from the most recently acquired `loadObject`. To receive an alert when a load object is rejected, log in to Control Center, select Alerts from the Common Services category, then create a Load Object File Invalid or Cannot be Fetched alert. Learn more.

`loadServers`	Array	Specifies a list of servers from which to request the load object. The value needs to contain IPv4 or IPv6 addresses, or DNS names that contain A or AAAA records. If a DNS name has both A and AAAA records, then GTM picks one randomly. For IP addresses, don't use non-routable RFC 1918 addresses.

`nickname`	String	A descriptive label for the data center.
`scorePenalty`	Integer	From v1.3. Influences the score for a data center. Giving a positive penalty increases the score and drives traffic away from the data center. Giving a negative penalty reduces the score and draws in more traffic that would otherwise go elsewhere. As the score is measured in milliseconds of ping time, very small numbers like 1 or 2 have virtually no effect. Typically, penalties are given in the tens or hundreds. Note that `scorePenalty` applies only for properties that use performance load balancing.
`stateOrProvince`	String	Specifies a two-letter ISO 3166 country code for the state or province where the data center is located.
`virtual`	Boolean	Indicates whether or not the data center is `virtual` or physical, the latter meaning the data center has an Akamai Network Agent installed, and its physical location in latitude and longitude is fixed. Either `true` if `virtual` or `false` if physical.
`Domain.resource.datacenters[].defaultLoadObject`
`loadObject`	String	Specifies the load object that GTM requests. A load object is a file that provides real-time information about the current load, maximum allowable load, and target load on each resource. The value cannot begin with a `:` character, and is limited to a maximum of 256 characters.
`loadObjectPort`	Integer	Specifies the TCP port to connect to when requesting the load object. A value of `0` means to use the default port, equivalent to either `80` or `443`.
`loadServers`	Array	Specifies a list of servers to request the load object from. The value needs to contain IPv4 or IPv6 addresses, or DNS names that contain A or AAAA records. If a DNS name has both A and AAAA records, then GTM picks one randomly. For IP addresses, don't use non-routable RFC 1918 addresses.

`Domain.resource.links[]`
`href`	String	Provides a hypermedia link to the complete URL that uniquely defines a resource.
`rel`	String	Indicates the link relationship of the object.
`Domain.resource.properties[]`
`backupCName`	String	Specifies a `backupCName`. If GTM declares that all of the servers configured for your property are down, and you configured a `backupCName`, then queries for the property return the `backupCName`. If a `backupCName` is set, don't set a `backupIp`.
`backupIp`	String	Specifies a backup IP. When GTM declares that all of the targets are down, it hands out the `backupIP`. The IP type coincides with the property's `iPv6` setting. If a `backupIp` is set, don't set a `backupCName`.
`balanceByDownloadScore`	Boolean	Indicates whether download score based load balancing is enabled. GTM estimates the load on your data centers based on how long they take to respond to GTM liveness tests. The advantage: you don't need to implement a load object. The disadvantage: it's a very crude measure of load, and usually highly nonlinear. As load increases, download times don't increase significantly, until there's too much load. When that happens, the download times skyrocket. This can easily cause erratic load balancing or load oscillations.
`cname`	String	Indicates the fully qualified name aliased to a particular property. The public name of the property.
`comments`	String	Provides information about the purpose of the property.
`dynamicTTL`	Integer	Indicates the TTL in seconds for records that might change dynamically based on liveness and load balancing such as A and AAAA records, and CNAMEs. The value ranges from `30` to `3600` and can change on request. The default is `60`.
`failbackDelay`	Integer	Specifies the failback delay in seconds. The minimum value is `0`. If specified, when a server has been down and comes back up, (that is, its liveness test starts succeeding again), GTM only considers it up after the failback delay has elapsed and tests continue to succeed.
`failoverDelay`	Integer	Specifies the failover delay in seconds. The minimum value is `0`. If specified, when a server begins failing its liveness test, GTM only considers it down after the failover delay has elapsed and the errors persist.
`ghostDemandReporting`	Boolean	From v1.3. Enables reporting of unmet content requests received by edge servers, analyzing demand for unserved content.
`handoutLimit`	Integer	From v1.3. Indicates the limit for the number of live IPs handed out to a DNS request. The `handoutLimit` applies only if `handoutMode` is set to either `normal` or `persistent` for the property. If applicable, the `handoutLimit` default value is `8` or `null` if not.
`handoutMode`	String	Specifies how IPs are returned when more than one IP is alive and available. Either `normal`, `persistent`, `one-ip`, `one-ip-hashed`, or `all-live-ips`. The default is `normal`. Handout mode is relevant only when you have more than one server IP in a data center.
`healthMax`	Number	Defines the absolute limit beyond which IPs are declared unhealthy. If backup CNAMEs are provided for a property, then it's reasonable for all IPs to be declared unhealthy. The `healthMax` value is multiplied by the smaller of the `timeoutPenalty` and the `errorPenalty`. This check declares as down any server with a score greater than this product. The default value is `null`.
`healthMultiplier`	Number	Configures a cutoff value that's computed from the median scores. Any server with a score over the cutoff value is considered down, and load isn't sent to it. The cutoff is computed from the minimum score across all data centers, for a given property and two object members: `healthMultiplier` and `healthThreshold`. The cutoff is either `healthMultiplier` (default value: 1.5) times the minimum score, or the `healthThreshold` (default value: 4), whichever is greater. See also `healthThreshold` within this object. For more information on how to determine server liveness, see the Global Traffic Management User Guide.
`healthThreshold`	Number	Configures a cutoff value that's computed from the median scores. Any server with a score over the cutoff value is considered down, and load isn't sent to it. See also `healthMultiplier` within this object. For more information on how to determine server liveness, see the Global Traffic Management User Guide.
`ipv6`	Boolean	Indicates the type of IP address handed out by a property. A `true` value indicates that all IP addresses specified are IPv6, and all hostnames need to resolve to AAAA records. A `false` value indicates IPv4 addresses, and all hostnames need to resolve to A records.
`lastModified`	String	An ISO 8601 timestamp that indicates when the property was last changed.
`links`	Array	A URL path that allows direct navigation to the property.
`links[]`	Object	Lists navigable URLs to resources.
`livenessTests`	Array	Liveness tests, which run periodically to determine whether your servers respond to requests, as discussed in API concepts.
`livenessTests[]`	Object	Liveness tests, which run periodically to determine whether your servers respond to requests, as discussed in API concepts.
`loadImbalancePercentage`	Number	Indicates the percent of load imbalance factor (LIF) for the domain. It lets GTM exceed the value configured for traffic distribution. For example, if the data center's traffic allocation is 25 percent and the LIF is 1.5, the demand can grow to 37.5 percent (25% × 1.5) before the load balancer starts shifting load away from it. If the LIF is `0`, no load imbalance is allowed. However, internally, GTM adds one to the LIF to allow its use as a multiplier. The default LIF is 1.1, which is displayed as `10.0` percent. The value ranges from `0` to `1000000` percent.
`mapName`	String	A descriptive label for a geographic map or a CIDR map that's required if the property is either `geographic` or `cidrmapping`, in which case `mapName` needs to reference either an existing geographic map or CIDR map in the same domain.
`maxUnreachablePenalty`	Number	For `performance` domains, this specifies a penalty value that's added to liveness test scores when data centers show an aggregated loss fraction higher than the penalty value. The penalty value is either `maxUnreachablePenalty` (minimum value is `0` and the default is `null`) or `unreachableThreshold` (decimal between `0` and `1`. A value of 1.0 or `null` disables an unreachable penalty). See also `unreachableThreshold` within this object.
`minLiveFraction`	Number	From v1.3. Specifies what fraction of the servers need to respond to requests so GTM considers the data center up and able to receive traffic. For example, if your data center contains eight servers, and the `minLiveFraction` value is `0.5`, then at least four servers need to respond to requests. Conversely, if five servers are down, and three servers are up, then GTM considers the entire data center down. Optional when a `minLiveFraction` value exists or not `null`.
`mxRecords`	Array	Specifies the MX records handed out to `MX` record type queries. Note that mapping and liveness testing aren't done. The same MX records are handed out for every request.
`mxRecords[]`	Object
`name{Hostname}`	String	The hostname.
`name{apex}`	String	The APEX name.
`scoreAggregationType`	String	Specifies how GTM aggregates liveness test scores across different tests, when multiple tests are configured. Values are `mean`, `median`, `best`, or the default `worst`.

The value ranges from `0` to `30000`. See also `stickinessBonusPercentage` within this object. To learn more about how these object members relate to each other, see API concepts.
`stickinessBonusPercentage`	Integer	Specifies a percentage used to configure data center affinity. This only applies if the property `type` is `performance` and the domain `type` is `full`. The value ranges from `0` to `100`. See also `stickinessBonusConstant` within this object. To learn more about how these object members relate to each other, see API concepts.
`trafficTargets`	Array	This specifies where to direct data center traffic. For geographic mapped properties, it's always a `cname`. For mirror failover properties, it can be any set of servers. For load balanced properties, this is a set of servers that are all within the same data center. You can assign multiple traffic targets to the same data center.
`trafficTargets[]`	Object	This specifies where to direct data center traffic. For geographic mapped properties, it's always a `cname`. For mirror failover properties, it can be any set of servers. For load balanced properties, this is a set of servers that are all within the same data center. You can assign multiple traffic targets to the same data center.
`type`	String	Specifies the load balancing behavior for the property. Either `failover`, `geographic`, `cidrmapping`, `weighted-round-robin`, `weighted-hashed`, `weighted-round-robin-load-feedback`, `qtr`, `performance`, `performance-with-load-feedback`, `asmapping`, `static`, or `ranked-failover`. See API versioning for more information.
`unreachableThreshold`	Number	For `performance` domains, this specifies a penalty value that's added to liveness test scores when data centers have an aggregated loss fraction higher than this value. The value is a decimal between `0` and `1`. A value of `1.0` or `null` disables an unreachable penalty. See also `maxUnreachablePenalty` within this object.
`useComputedTargets`	Boolean	For `load-feedback` domains only, this specifies that you want GTM to automatically compute target load. Report only the current load objects, either by omission, or by using non-XML load objects.

`disableNonstandardPortWarning`	Boolean	Disables warnings when non-standard ports are used. For example, GTM doesn't emit a warning to specify port 1234 when the `testObjectProtocol` is `http`, as HTTP typically uses port 80. The default is `false`.
`disabled`	Boolean	From v1.4. Disables the liveness test. When disabled, GTM stops running the test, treating it as if it no longer exists. The default is `false`.
`errorPenalty`	Number	From v1.2. Specifies the score that's reported if the liveness test encounters an error other than timeout, such as connection refused, and 404. The default value is `75`.
`hostHeader`	String	Sent if the `testObjectProtocol` is `http` or `https`, up to 256 non-space, alphanumeric characters. Obsolete as of version 1.4. You should use `hostHeaders` instead.

`ttl`	Integer	From v1.4. The number of seconds that this record should live in a resolver's cache before being refetched.
`type`	String	From v1.4. The record type.
`Domain.resource.properties[].trafficTargets[]`
`datacenterId`	Integer	A unique identifier for an existing data center in the domain.
`enabled`	Boolean	Indicates whether the traffic target is used. You can also omit the traffic target, which has the same result as the `false` value. However, when the value is `false`, GTM continues to store the other traffic target fields in the database. There's no need to store them locally should you want to use the traffic target at a later time.
`handoutCName`	String	Specifies an optional data center for the property. Uses the `handoutCName` when there are no servers configured for the property. Maximum 63 characters for the labels, 255 characters overall. May contain alphanumeric, hyphens, and underscores, but not literal IP addresses. Leading or trailing hyphens aren't allowed.
`name`	String	An alternative label for the traffic target.
`precedence`	Number	From v1.6. For use by `ranked-failover` type properties, the lower the number, the higher the precedence.
`servers`	Array	Identifies the IP address or the hostnames of the servers. For hostnames that return IP addresses, tests all IP addresses for liveness.
`weight`	Number	Specifies the traffic weight for the target. This is required when the enclosing property is `failover`, `weighted`, `weighted-with-load-feedback`, or `performance`. The sum of this value, for all enabled targets, can be any number, percentage, or ratio. For example, you can express a traffic split as 60/40, 120/80, or 3/2, all equivalent values. For `failover` properties, set this value to `1` for the traffic target you want to mark as primary.
`Domain.resource.resources[]`
`aggregationType`	String	Specifies how GTM handles different load numbers when multiple load servers are used for a data center or property. Either `sum`, `median`, or `latest`. For test time load feedback, consider `median`. (Akamai conducts tests from multiple locations, so you can ignore outlying values.) For load feedback with manual targets or dynamic targets, consider `latest` because all load servers normally report similar numbers.
`constrainedProperty`	String	Specifies the name of the property that this resource constrains, or `**` to constrain all properties.
`decayRate`	Number	For internal use only. Unless Akamai indicates otherwise, omit the value or set it to `null`.
`description`	String	A descriptive note to help you track what the resource constrains. For example, `aggregate bandwidth for all properties`. A maximum of 256 characters.
`hostHeader`	String	Optionally specifies the host header used when fetching the load object.
`leaderString`	String	Specifies the text that comes before the `loadObject`. GTM assumes that the current load is the first number to appear after this text, minus any white space. The value is a maximum of 256 characters. The default is `null`. For example, suppose your `loadObject` file contains, This is a load object. TheLoadIs:497. This is the end of the load object. Then GTM reads the current load as 497 if the `leaderString` is set to TheLoadIs.
`leastSquaresDecay`	Number	For internal use only. Unless Akamai indicates otherwise, omit the value or set it to `null`.
`links`	Array	Specifies the URL path that allows direct navigation to the resource.
`links[]`	Object	Lists navigable URLs to resources.
`loadImbalancePercentage`	Number	Indicates the percent of load imbalance factor (LIF) for the domain. It lets GTM exceed the value configured for traffic distribution. For example, if the data center's traffic allocation is 25 percent and the LIF is 1.5, the demand can grow to 37.5 percent (25% × 1.5) before the load balancer starts shifting load away from it. If the LIF is `0`, no load imbalance is allowed. However, internally, GTM adds one to the LIF to allow its use as a multiplier. The default LIF is 1.1, which is displayed as `10.0` percent. The value ranges from `0` to `1000000` percent.
`maxUMultiplicativeIncrement`	Number	For internal use only. Unless Akamai indicates otherwise, omit the value or set it to `null`.
`name`	String	A descriptive label for the resource. A maximum 150 non-space characters.
`resourceInstances`	Array	The `resources` that constrain the `properties` within the data center.
`resourceInstances[]`	Object
`type`	String	Indicates the kind of `loadObject` format used to determine the load on the resource. Either `XML load object via HTTP`, `XML load object via HTTPS`, `Non-XML load object via HTTP`, `Non-XML load object via HTTPS`, `Download score`, or `Push API`.
`upperBound`	Integer	An optional sanity check that specifies the maximum allowed value for any component of the load object. If the `loadObject` contains a number that exceeds this value, it rejects the entire load object as invalid and GTM continues to use the load values from the most recently acquired `loadObject`. To receive an alert when a load object is rejected, log in to Control Center, select Alerts from the Common Services category, then create a Load Object File Invalid or Cannot be Fetched alert.

`loadObject`	String	Identifies the load object file used to report real-time information about the current load, maximum allowable load, and target load on each resource. The maximum permitted length is 256 characters. Learn more.
`loadObjectPort`	Integer	Specifies the TCP port of the `loadObject`. The value ranges from `0` to `65535`. If the value is `0`, the default port is either `80` or `443`.
`loadServers`	Array	Specifies a list of servers from which to request the load object. The value needs to contain IPv4 or IPv6 addresses, or DNS names that contain A or AAAA records. If a DNS name has both A and AAAA records, then GTM picks one randomly. For IP addresses, don't use non-routable RFC 1918 addresses.
