Todd Lipcon commented on KUDU-2297:
-----------------------------------
Moving existing kernel_stack_watchdog traces out of LOG(INFO) and into the
diagnostics log might be a nice idea, since people are often confused when they
see them.
> 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
> Priority: Major
>
> 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.
