Change Summary
Split out from the original combined PR #2717.
Adds a contrib receiver for Linux user_events tracepoints.
The receiver supports two decode formats:
tracefs: generic Linux tracepoint decoding based on the static schema exposed in tracefs format files.event_header: decodes self-describing EventHeader payloads. EventHeader comes from the Microsoft LinuxTracepoints-Rust project, but is open and usable by any producer.The receiver uses
one_collectforperf/user_eventscollection, and supports single or multiple subscriptions, batching, late registration, and basic receiver metrics. It is behind theuserevents-receiverfeature flag.Also adds a Linux CI smoke test that registers and reads both tracefs and EventHeader user_events tracepoints when kernel support is available.
What issue does this PR close?
How are these changes tested?
Added Linux CI smoke test
Are there any user-facing changes?
