opentelemetry-collector-co VS cockpit-podman

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.

Hey, I have homelab NUC server where I run different services as rootless podman pods and containers running by dedicated users, eg. nextcloud pod running by nextcloud user, gitea by gitea, znc by znc and more. Next step was trying to monitor these services. First trey was using cockpit-podman feature, but in UI I see only containers of my user and rootfull which both was empty. I cannot switch to another user because the're not capable for login to cockpit. Now I'm testing prometheus and podman-exporter which seems ok, but again I see containers only if I run prometheus-podman-exporter service as user who run another podman container (e.g. as nextcloud user). Of course I can run this service parallel as dedicated user with another port and add them as target to prometheus scrape config but from obvious reason I want to avoid that. Is it more gentle way to monitor my pods? I know that those namespaces are one of the main feature of Podman but I don't consider this before my deploys :)

Cockpit has a podman module (cockpit-podman)

Tested podman to replace docker (the cli) on a mac yesterday Most of it works fine. They have an easy way to setup a vm now with `podman machine`: https://podman.io/getting-started/installation#macos

If you want the management GUI, install cockpit: https://github.com/cockpit-project/cockpit-podman

Try podman, you'll be impressed.
