Monitoring temporal using Prometheus

The operator provides support for prometheus to monitor your Temporal cluster. When metrics exposition is enabled, the operator adds prometheus service discovery annotations on each temporal components:

• prometheus.io/scrape
• prometheus.io/scheme
• prometheus.io/path
• prometheus.io/port

If you're using prometheus-operator, please check the dedicated documentation page: Monitoring temporal using prometheus-operator
