Monitoring

The managed Trino instances are automatically configured to export Prometheus metrics. See Monitoring for more details.

Metrics

Trino automatically exposes built-in Prometheus metrics on coordinators and workers. The metrics are available on the http (8080/metrics) or https (8443/metrics) port, depending on the TLS settings.

The following ServiceMonitor example, demonstrates how the metrics could be scraped using the Prometheus Operator.

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: scrape-label
spec:
  endpoints:
  - port: https # or http
    scheme: https # or http
    path: /metrics
    basicAuth: (1)
      username:
        name: trino-user-secret
        key: username
      password:
        name: trino-user-secret
        key: password
  jobLabel: app.kubernetes.io/instance
  namespaceSelector:
    any: true
  selector:
    matchLabels:
      prometheus.io/scrape: "true"
