-Some Arvados services publish Prometheus/OpenMetrics-compatible metrics at @/metrics@, and some provide additional runtime status at @/status.json@.  Metrics can help you understand how components perform under load, find performance bottlenecks, and detect and diagnose problems.
+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.

-h2. Keep-web
+The plain text export format includes "help" messages with a description of each reported metric.
 
-Keep-web exports metrics at @/metrics@ -- e.g., @https://collections.zzzzz.arvadosapi.com/metrics@.
+When configuring Prometheus, use a @bearer_token@ or @bearer_token_file@ option to authenticate requests.
