Ddapm-test-agent

New Features

- Add support for distributed traces where an instrumented service sends a trace chunk where the root span has a parent not in the trace chunk.
- Build an ARM64 version of the Docker image as a multi-arch image.

New Features

- Better snapshot error messages for unexpected number of traces received.

Bug Fixes

- Fix not present parent_id in snapshots. It should be normalized to 0.

Bug Fixes

- Handle span `parent_id` being undefined.

Bug Fixes

- Normalize trace stats snapshots using all the aggregation fields. This fixes an issue where snapshots could fail due to ordering of buckets.
- Use HTTPStatusCode in trace stats snapshots. This field was missing.

New Features

- Add `/test/session/requests` endpoint to return all requests made to the test agent for a given session token.

- Add support for the `/v0.6/stats` endpoint. All requests made to the endpoint will be stored and can be retrieved via the `/test/session/requests` or `/test/session/stats` endpoints. Note that snapshotting for stats is not yet implemented.

- Implement trace stats snapshotting.

Trace stats are now included in the snapshot behaviour provided by the testagent.

Similar to traces, trace stats snapshots are output to a json file.

Bug Fixes

- Fix custom snapshot filenames. Custom filenames are not supposed to include the file extension.

Bug Fixes

- Fix log messages in `ddapm-test-agent-fmt`.
