# What's in an mPulse Beacon (Web Apps) The content of this page applies to mPulse web apps. mPulse is built on top of the [boomerang JavaScript library](https://github.com/akamai/boomerang) which collects web performance data from a user’s web browser and sends the data back to the mPulse servers via a beacon. _Beacons_ are invisible network requests that contain performance data and other page-load characteristics. All of this data is included on the beacon via HTTP headers or as part of the query string or form payload. Within the web performance community, this data is commonly called _RUM_ or _Real User Measurement_ data because it involves measuring the experience of real users. In this document, we will describe the various parameters collected via the boomerang beacon as well as how they are mapped to other parts of mPulse such as S3, Asgard and DSWB. As of April 2020, all IP addresses are truncated. IPv4 IPs are truncated to /24 (e.g. `1.2.3.4` to `1.2.3.0`) and IPv6 IPs are truncated to /64 (e.g. `aaaa:bbbb:cccc:dddd:eeee:ffff:gggg:hhhh` to `aaaa:bbbb:cccc:dddd::`). # Top Level Fields | Field | Query String Param | S3 | Asgard | DSWB BEACON_TABLE var | Examples | Description | | :--------------------- | :----------------- | :----------------------- | :--------------------- | :-------------------- | :--------------------------------------------------------------------------------------------------------------------------------------- | :------------------------------------------------------------------------------------------------------------------------------------------ | | Log Type | \-- | `type` | \-- | \-- | `beacon` `batch` | mPulse log type | | Beacon ID | \-- | `id` | `beaconId` | \-- | `xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx` | Beacon GUID | | Domain | `h.d` | `domain` | \-- | `domain` | `website.com` | Registered domain or registered dev domain in mPulse of the page sending the beacon | | Domain ID | \-- | `domainid` | `appid` | \-- | `123` | Registered domain ID | | Timestamp | \-- | `timestamp` | `timestamp` | `timestamp` | `1512086400000` | Server timestamp when beacon arrived ([Unix epoch](https://en.wikipedia.org/wiki/Unix_time)) | | Page ID | `pid` | `page_id` | `pageId` | \-- | `abcd1234` | Page ID | | Beacon Number | `n` | `n` | `additionalfieldsjson` | \-- | `1` | Beacon number for current page | | API Key | `h.key` | `key` | \-- | `key` | `XXXXX-XXXXX-XXXXX-XXXXX-XXXXX` | mPulse API Key assigned to this domain | | Beacon HTTP Method | \-- | `http_method` | \-- | `httpMethod` | `GET` `POST` | HTTP Request method used to send the beacon (for internal use only) | | Beacon HTTP Version | \-- | `http_version` | \-- | `httpVersion` | `HTTP/1.1` | HTTP Version used to send the beacon (for internal use only) | | Beacon Referrer | \-- | `http_referrer` | \-- | `beaconReferrer` | `http://referrer.com` | URL of the page that sent the beacon.

On the beacon, these metrics have the prefix `cmet.`, followed by a sanitized version of the metric name. In the S3 logs, these metrics are all numerically indexed. Example: ``` ... custom_metrics: { "0": 10, "5": 1 }, ... ``` Metric values are always numeric. Currency values are always in the lowest unit (eg, ¢ rather than $).

This does not include the times that may or may not have been spent forwarding the requests to the origin. - `originTime`: The sum of the round-trip times between the Akamai edge server (nearest to the origin), and the origin, for this Asset Type. This includes the time the origin spends handling the requests. | Query String Param | S3 | Asgard | DSWB BEACON_TABLE var | Examples | Description | | :----------------- | :----------------- | :--------------- | :-------------------- | :------------------------------------------- | :------------------------------ | | n/a | `restiming.[type]` | `[type][metric]` | \-- | `26,833151,3061949,1153,10000_7269,0,5,1000` | Summarized Resource Timing data | ## User Timing Data User Timing data comes from the [Boomerang UserTiming Plugin](https://akamai.github.io/boomerang/BOOMR.plugins.UserTiming.html).
