Application Metrics Units

Those metrics listed on the page you referenced apply to Jira Server and Data Center, not Jira Cloud. Jira Cloud doesn’t expose the same Dropwizard-based application metrics or JMX endpoints, since Atlassian manages the infrastructure and performance telemetry internally.

If you’re running Jira Cloud, there’s no supported way to access those raw metrics. Instead, you can monitor performance using Atlassian’s [cloud status pages](
