+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.
+
+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.
+
+<pre>curl -sfH "Authorization: Bearer your_management_token_goes_here" "https://0.0.0.0:25107/metrics"
+</pre>
+
+The plain text export format includes "help" messages with a description of each reported metric.
+
+When configuring Prometheus, use a @bearer_token@ or @bearer_token_file@ option to authenticate requests.
+
+<pre>scrape_configs:
+ - job_name: keepstore
+ bearer_token: your_management_token_goes_here
+ static_configs:
+ - targets:
+ - "keep0.ClusterID.example.com:25107"
