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

> 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.
