Simon Cruanes	9c3e2a7076	feat: pass ?stop atomic; allow for multiple background threads	2022-07-06 12:53:00 -04:00
Simon Cruanes	331ae94547	detail	2022-07-06 12:52:03 -04:00
Simon Cruanes	d689dfc8fb	feat(ocurl): simpler, cleaner backend implementation ... we now only have a single representation of a batch, with its own internal state to handle timeouts. It handles its own locking, and there are no callbacks anymore.	2022-07-06 12:06:51 -04:00
Simon Cruanes	85b6e91615	config: more comments; make Config.t private ... forcing users to use `Config.make` to build a new config means we can add fields without breaking existing code.	2022-07-06 12:06:12 -04:00

Simon Cruanes	a718f049aa	fix: ensure we can always produce random trace_id/span_id	2022-05-04 12:47:33 -04:00
Pau Ruiz Safont	fa3b863625	feat: Allow setting API headers ... This can be done through the API or by setting OTEL_EXPORTER_OTLP_HEADERS Signed-off-by: Pau Ruiz Safont <pau.safont@citrix.com>	2022-05-04 16:56:37 +01:00
Simon Cruanes	5fefcf3ced	require pbrt only, use ocaml-protoc as a lint	2022-05-03 13:52:20 -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	1bedb57123	feat: implement basic support for logs ... also send them to the collector.	2022-04-28 09:57:28 -04:00
Simon Cruanes	9d4bb5a97f	feat: debug the library is set via OTEL_OCAML_DEBUG	2022-04-19 13:28:55 -04:00

Matt Bray	1919154085	add runtime attrs to GC stats	2022-04-12 16:26:08 +01:00
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	786ebb611a	ocurl-client: reset needs_gc_metrics	2022-04-11 15:29:32 -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
