Pull request overview
Documents the new diagnostics_channel bypass API (from #63651) so observability tooling can opt specific subscribers/stores into suppression during internal operations, avoiding recursive instrumentation.
Changes:
- Added new API docs for
diagnostics_channel.bypass(key, fn[, thisArg[, ...args]])with multiple examples (APM recursion avoidance, async propagation, multi-tool coordination). - Extended documentation for
channel.subscribe(),channel.bindStore(), andtracingChannel.subscribe()to include anoptions.bypassIdparameter. - Added cross-reference link for
diagnostics_channel.bypass().
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
