Simon Cruanes	080e0de138	Update src/opentelemetry.ml ... Co-authored-by: Matt Bray <mattjbray@gmail.com>	2022-04-30 13:26:12 -04:00
Simon Cruanes	6744123075	feat(otel): Metrics_callbacks module ... this module allows the user's programs and libraries to register some callbacks that will be regularly called to produce metrics.	2022-04-29 16:50:06 -04:00
Simon Cruanes	198027a519	add histogram metrics (untested)	2022-04-28 10:17:36 -04:00

Simon Cruanes	2149bb0714	fix: proper starting point for cumulative metrics ... use the start of the program as a fixed reference point. see: https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/datamodel.md#temporality	2022-04-26 10:08:56 -04:00

Simon Cruanes	01b31b471c	doc: improve docs for main module	2022-04-15 17:52:22 -04:00
Simon Cruanes	c950ffc885	feat: use a ref for Globals.global_attributes ... sometimes it's useful to be able to modify them from the code itself. For example a client or service might generate a unique Uuidm for its whole lifetime, and add that as an attribute to later filter on it.	2022-04-15 08:59:13 -04:00
Simon Cruanes	71b999a5b7	use conventions	2022-04-12 12:04:49 -04:00

See https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/semantic_conventions/runtime-environment-metrics.md#runtime-environment-specific-metrics---processruntimeenvironment	2022-04-12 16:08:58 +01:00
Simon Cruanes	1ca14b3a51	fix: name of metrics	2022-04-11 18:16:50 -04:00
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
