Simon Cruanes	3d0d031bcd	fix: yet another fix for emitting GC metrics ... now, the frontend (Opentelemetry) is responsible for signalling the backend when to emit GC stats; but the backend just samples GC metrics on the next `tick()` and pushes them in the next batch. This saves us from having to worry about re-entrancy and GC metrics being emitted during the emission of something else.	2022-04-11 16:33:01 -04:00

Simon Cruanes	5180be31bc	feat(collector): move GC metrics logic to the collector ... this helps avoiding reentrancy issue, where the collector allocates, triggers the GC metrics alarm, which tries to push new metrics in the middle of a batch (currently leading to a potential deadlock).	2022-04-11 13:09:13 -04:00
