Prometheus Metrics for On-prem Users

BuildBuddy exposes Prometheus metrics that allow monitoring the four golden signals: latency, traffic, errors, and saturation.

Prometheus metrics are exposed under the path metrics/ on port 9090 by default.

To view these metrics in a live-updating dashboard, we recommend using a tool like Grafana.

Examples​

# Number of invocations per second by invocation status
sum by (invocation_status) (rate(buildbuddy_invocation_count[5m]))
