This is a draft page; the published version of this page can be found at UCS/Current/UCSPEGuide/Metrics.

Learn which metrics you should monitor for <service_name> and when to sound the alarm.

Include a link to the "suite-level" documentation for monitoring:
#mintydocs_link must be called from a MintyDocs-enabled page (Draft:UCS/Current/UCSPEGuide/Metrics).

Describe metrics (compatible with Prometheus endpoints) that customers can use to create their own monitoring dashboard in a tool like Grafana.

Make to identify any metrics that are important to monitor for alarming purposes, and include sample thresholds the customer should alarm on.
UCS-X provides internal monitoring metrics through a Prometheus endpoint on port 10052.
