13 Some Arvados services publish Prometheus/OpenMetrics-compatible metrics at @/metrics@. Metrics can help you understand how components perform under load, find performance bottlenecks, and detect and diagnose problems.
14
15 To access metrics endpoints, services must be configured with a "management token":management-token.html. When accessing a metrics endpoint, prefix the management token with @"Bearer "@ and supply it in the @Authorization@ request header.

17 <pre>curl -sfH "Authorization: Bearer your_management_token_goes_here" "https://0.0.0.0:25107/metrics"
18 </pre>
19
20 The plain text export format includes "help" messages with a description of each reported metric.
21
22 When configuring Prometheus, use a @bearer_token@ or @bearer_token_file@ option to authenticate requests.
