SigNoz
Go from a service latency chart to its traces and their logs in one tool: OpenTelemetry observability on ClickHouse, with five services to run if you self-host.
Netdata
Per-second metrics with nothing to configure, from a GPL agent. Reading logs takes a Netdata Cloud login; seeing more than five nodes takes a paid plan.
