---------------------------------

             Summary: Expand metrics logging into a general purpose diagnostics 
log
                 Key: KUDU-2297
                 URL: https://issues.apache.org/jira/browse/KUDU-2297
             Project: Kudu
          Issue Type: Improvement
          Components: ops-tooling, supportability
    Affects Versions: 1.6.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


Currently Kudu servers have the ability to periodically dump metrics to the 
log. KUDU-2279 improved the compactness and performance of the log so it can be 
enabled by default.

In addition to metrics, though, it would be useful to have some other 
machine-readable data periodically recorded by servers. For example, periodic 
stack traces or RPC traces could be helpful for understanding latency issues 
after-the-fact. This JIRA tracks the effort to convert the metrics log to a 
more general-purpose diagnostics log.
