What are Coroot and Prometheus?
Coroot
Coroot is an open-source observability tool that uses eBPF to gather metrics, logs, traces, and profiles with zero instrumentation. It automatically surfaces service maps, SLOs, and root-cause insights.
- eBPF zero-instrumentation telemetry
- Automatic service maps
- Built-in SLO tracking
- Root-cause analysis
Prometheus
Prometheus is a metrics-based monitoring system and time-series database with a powerful query language and alerting. It targets engineers monitoring cloud-native infrastructure. It is deployed via Docker, binaries, or Helm.
- Pull-based metrics collection
- PromQL query language
- Built-in alerting rules
- Cloud-native standard
Coroot vs Prometheus: key differences
Both projects are written in Go. Prometheus is the lighter option, starting around 512 MB of RAM against 1,024 MB for Coroot. Prometheus is the more established project (first released 2015), while Coroot arrived in 2022. Prometheus has the considerably larger community, at 66,196 GitHub stars versus 7,936.
