SigNoz
Open-source observability platform for traces, metrics, and logs built on OpenTelemetry.
HN commenters like SigNoz as an OpenTelemetry-native backend123 with good dashboards and trace and metrics monitoring4, plus an API they can script or query programmatically.56 The main caveat is weak alerting, which one user covers by also running Sentry.7
