You can configure a data stream to collect these parameters. To get a list of available parameters, you can run the List data set fields operation.

Some data sets may not be available for logging depending on the product enabled for the property you want to monitor. For example, Web security and EdgeWorkers information data set fields are not supported for the Cloud Wrapper products.

If you're looking for sample logs (JSON and structured) with data, see Log format.

Midgress traffic

You can use DataStream 2 to log midgress traffic on your property, such as between two Akamai edge servers. Using the Create a stream or Edit a stream operations, set the collectMidgress member to true, and go to Property Manager to enable the Collect midgress traffic option in the DataStream behavior for your property. As a result, the second place in the log line contains a numeric value:

  • 0, if the request was processed between the client device and edge server (CLIENT_REQ), and isn't logged as midgress traffic
  • 1, if the request was processed by an edge server within the region (PEER_REQ), and is logged as midgress traffic
  • 2, if the request was processed by a parent Akamai edge server in the parent-child hierarchy (CHILD_REQ), and is logged as midgress traffic‚Äč

When you enable logging midgress traffic from your stream, the Get a stream operation returns the collectMidgress member as true and lists the isMidgress data set field together with other data set fields you log in the stream. If the logging midgress traffic feature is not enabled on your contract, contact the Akamai support team.
