> Trigger JFR session when under duress -- e.g. backed-up request queue count

>
> Chatting today w/ a mighty hbase operator on how to figure what is happening
> during transitory latency spike or any other transitory 'weirdness' in a
> server, the idea came up that a java flight recording during a spike would
> include a pretty good picture of what is going on during the time of duress
> (more ideal would be a trace of the explicit slow queries showing call stack
> with timings dumped to a sink for later review; i.e. trigger an htrace when a
> query is slow...).
> Taking a look, programmatically triggering a JFR recording seems doable, if
> awkward (MBean invocations). There is even a means of specifying 'triggers'
> based off any published mbean emission -- e.g. a query queue count threshold
> -- which looks nice. See
> https://community.oracle.com/thread/3676275?start=0&tstart=0 and
> https://docs.oracle.com/javacomponents/jmc-5-4/jfr-runtime-guide/run.htm#JFRUH184
> This feature could start out as a blog post describing how to do it for one
> server. A plugin on Canary that looks at mbean values and if over a
> configured threshold, triggers a recording remotely could be next. Finally
> could integrate a couple of triggers that fire when issue via the trigger
> mechanism.
> Marking as beginner feature.
