What are Coroot and Pushgateway?
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
Pushgateway
The Prometheus Pushgateway allows ephemeral and batch jobs to expose their metrics to Prometheus. Jobs push metrics to the gateway, which Prometheus then scrapes on its regular schedule.
- Accepts pushed metrics
- Bridges batch jobs to Prometheus
- Persists metrics to disk
- Tiny footprint
Coroot vs Pushgateway: key differences
Both projects are written in Go. Pushgateway is the lighter option, starting around 32 MB of RAM against 1,024 MB for Coroot. Pushgateway is the more established project (first released 2015), while Coroot arrived in 2022. Coroot has the considerably larger community, at 7,936 GitHub stars versus 3,369.
