- Large ecosystem and exporters
- Reliable alerting with Alertmanager
Cons
- Not ideal for high-cardinality labels
- Limited built-in dashboarding
- Requires tuning for large-scale cardinality
- Less suited for logs and traces without extensions
Verdict
Prometheus excels at metric collection and alerting for cloud-native environments. It suits teams needing fast PromQL analysis and strong Kubernetes observability. The main trade-off is limited native visualization and careful label design.
