GoogleDataTransport (FireLog BatchedLogRequest, Protobuf)

GoogleDataTransport (FireLog BatchedLogRequest, Protobuf) (google/googledatatransport-firelog-batchlog-protobuf)

operated by: Google LLC (get company information on datarequests.org)
The GoogleDataTransport SDK is a transport layer used internally by many other Firebase (e.g. Crashlytics, Performance, Core) Google (e.g. ML Kit) SDKs and services. Source It batches application-specific data from within an app to Google, using a common endpoint regardless of the actual SDK that was integrated by the app developer. Source

Endpoint URLs

These are URLs or regexes of endpoints the tracker sends data to. We use these to determine which adapter to apply to a request. Some trackers use the same endpoint for several formats. In this case we use additional logic to match the adapter to the request, refer to the code for more information.

Decoding steps

Every tracking library has its own way of transmitting tracking data, often even several. They are regularly pretty convoluted, nested encoding schemes. Because of that, the adapter needs to decode the request information into a consistent format. We try to keep keys and paths intact, but the structure results from our decoding. All steps used in the decoding for this adapter are documented here.
  1. Decode the request body as a protocol buffer (Protobuf). Store that in the result for the request body.
  2. Get the property at JSONPath $.1[?(@[2] === 462)].3.*.6 in the result for the request body. Store that in the result for the request body at logEvents_FIREPERF.
  3. Get the property at JSONPath $.1[?(@[2] === 1710)].3.6 in the result for the request body. Store that in the result for the request body at logEvents_GDT_CLIENT_METRICS.
  4. Get the property at JSONPath $.1[?(@[2] === 1974)].3.6 in the result for the request body. Store that in the result for the request body at logEvents_FIREBASE_APPQUALITY_SESSION.
  5. Get the property at JSONPath $.1[?(@[2] === 137)].3.6 in the result for the request body. Store that in the result for the request body at logEvents_FIREBASE_COREDIAGNOSTICS.
  6. Get the property at JSONPath $.1[?(@[2] === 1326)].3.*.6 in the result for the request body. Store that in the result for the request body at logEvents_FIREBASE_ML_LOG_SDK.

Observed data transmissions

This is data that we observed being transmitted by this tracker. Not every request contains all of this data. The context of the data describes where we found the data in the request, the path describes the location of the data in the decoded request. The examples are a selection of observed values.
