-------------------------------------
Summary: Revise the metrics docs in the website
Key: CASSANDRA-16602
URL: https://issues.apache.org/jira/browse/CASSANDRA-16602
Project: Cassandra
Issue Type: Bug
Components: Legacy/Documentation and Website
Reporter: Yifan Cai
Assignee: Yifan Cai
While inspecting the metrics code, I realized that the metrics docs (at
https://cassandra.apache.org/doc/latest/operating/metrics.html) has several
errors, e.g.
1. JMX MBean names have incorrect format. They should be separated with
commas, but the doc has space separated values. Cassandra users referring to
this docs will not get it working.
2. The MBean name for Keyspace metrics is wrong. In the code, we have
`keyspace=<Keyspace>`, instead of `scope=<Keyspace>`, which is listed in the
docs page.
3. There are outdated fields. For instance, the `SyncTime` has been
renamed to `RepairSyncTime` under the TableMetrics.
To avoid frustrating and confusing the users that refer to the metrics page,
the docs need to be revised.
