liqe VS opentelemetry-collector-co

Potentially useful resource – https://github.com/gajus/liqe

If anyone is looking to contribute, I would really appreciate someone taking over this issue.

It is not a particularly hard issue to solve but requires an understanding of Nearley.

you can add https://github.com/open-telemetry/opentelemetry-collector-co... at signoz's otel-collector which will scrape your service's endpoint periodically. If your service is down, this will give 5xx error and you can set an alert on that.

Another alternative is to use an alert to notify on a metric being absent for sometime. Both of these should work

The open telemetry collector does just that. https://github.com/open-telemetry/opentelemetry-collector-co...

If you are using the prometheus exporter, you can use the transform processor to get specific resource attributes into metric labels.

With the advantage that you get only the specific attributes you want, thus avoiding a cardinality explosion.

The article seems to suggest https://github.com/open-telemetry/opentelemetry-collector-co... was silently killed, yet it appears to have been merged in January, am I missing something?

OpenTelemetry is a large suite of software, that supports many use cases. I think you got what you wanted but didn't realised it!

The dedicated executable that you are after is called the OpenTelemtry Collector.

The OpenTelemetry SDK for language of choice should include many exporters, which describe the format and transport mechanism for the traces. The OpenTelemetry Collector can then use an appropriate receiver to ingest those traces.

Here is a file based receiver for the collector:

This arch is how the big players do it at scale (ie. datadog, new relic - the second it passes their edge it lands in a kafka queue). Also otel components lack rate limiting(1) meaning its super easy to overload your backend storage (s3).

Grafana has some posts how they softened the s3 blow with memcached(2,3).

Ah yeah the easiest way is probably using the OpenTelemetry collector to set up a process to pull your logs out of jounrnald and send them via otel logs to HyperDX (or anywhere else that speaks otel) - the docs might be a bit tricky to go around depending on your familiarity with OpenTelemetry but this is what you'd be looking for:

Happy to dive more into the discord too if you'd like!

What schema does SigNoz use with Clickhouse? The Open Telemetry Collector uses this schema https://github.com/open-telemetry/opentelemetry-collector-co... and I found out that accesing map attributes is much slower (10-50x) compared to regular columns. I expected some slow down but this is too much.

Podman does support docker API so you can use something like the OpenTelemetry Collector to fetch metrics using the docker API and forward them to prometheus.
