SigNoz is nice and has been pointed out already.
I use this for my own projects and I’m very happy with it: GitHub - openobserve/openobserve: Open source observability platform for logs, metrics, traces, frontend monitoring, pipelines and LLM observability. A sophisticated, simple and highly performant alternative to Datadog, Splunk, and Elasticsearch with 140x lower storage costs and single binary deployment. · GitHub
Though disclaimer: haven’t used it with Elixir yet, only Rust and Golang.
A very nice all-in-one APM solution.
