Project mention: Show HN: Kubetail – Real-time log search for Kubernetes | news.ycombinator.com | 2025-05-01
Look into https://logdy.dev . I've played around with it a little bit, but really putting some work into learning it and integrating it with OTEL traces is my next side project.
Another alternative is https://openobserve.ai/ . It needs to run as a daemon to ingest logs (instead of opening a file), but it has a really nice UI.

gigapipe
qryn is a polyglot, high-performance observability framework for ClickHouse. Ingest, store and analyze logs, metrics and telemetry traces from any agent supporting Loki, Prometheus, OTLP, Tempo, Elastic, InfluxDB and many more formats and query transparently using Grafana or any other compatible client.
I'm not the person you asked -- and I also want to be transparent that I only PoC-ed it and due to external circumstances didn't get it all the way out to production -- but I really like how https://github.com/metrico/qryn (AGPLv3) thinks about the world. It is, like SigNoz, unified (logs, metrics, traces) but it actually implements several of the common endpoint schemes allowing it to pretend to be "your favorite tool" which plausibly helps any integration story <https://github.com/metrico/qryn#%EF%B8%8F-query> and <https://github.com/metrico/qryn#-vendors-compatibility>
I was going to take advantage of Clickhouse using S3 as warm-to-cold storage since my mental model is that most logs, metrics, and traces are written and not read https://clickhouse.com/docs/en/integrations/s3#configuring-s...
I believe one could do that with SigNoz, too, so I don't mean to imply that trickery was qryn specific, just that I didn't want to get into the "constantly resizing io3 PVC" game

Project mention: How Netflix Accurately Attributes eBPF Flow Logs | news.ycombinator.com | 2025-04-08
At Coroot, we solve the same problem, but in a slightly different way. The traffic source is always a container (Kubernetes pod, systemd slice, etc.). The destination is initially identified as an IP:PORT pair, which, in the case of Kubernetes services, is often not the final destination. To address this, our agent also determines the actual destination by accessing the conntrack table at the eBPF level. Then, at the UI level, we match the actual destination with metadata about TCP listening sockets, effectively converting raw connections into container-to-container communications.
The agent repo: https://github.com/coroot/coroot-node-agent
