Exporter

The prow-exporter exposes metrics about prow jobs while the metrics are not directly related to a specific prow-component.

Metrics

Metric name	Metric type	Labels/tags
prow_job_labels	Gauge	job_name=<prow_job-name> job_namespace=<prow_job-namespace> job_agent=<prow_job-agent> label_PROW_JOB_LABEL_KEY=<PROW_JOB_LABEL_VALUE>
prow_job_annotations	Gauge	job_name=<prow_job-name> job_namespace=<prow_job-namespace> job_agent=<prow_job-agent> annotation_PROW_JOB_ANNOTATION_KEY=<PROW_JOB_ANNOTATION_VALUE>
prow_job_runtime_seconds	Histogram	job_name=<prow_job-name> job_namespace=<prow_job-namespace> type=<prow_job-type> last_state=<last-state> state=<state> org=<org> repo=<repo> base_ref=<base_ref>

For example, the metric prow_job_labels is similar to kube_pod_labels defined in kubernetes/kube-state-metrics. A typical usage of prow_job_labels is to join it with other metrics using a Prometheus matching operator.

Note that job_name is .spec.job instead of .metadata.name as taken in kube_pod_labels. The gauge value is always 1 because we have another metric prowjobs for the number jobs by name. The metric here shows only the existence of such a job with the label set in the cluster.
