If I have lots of fairly short-lived snapshots (from MapReduce jobs, which can spawn off lots of JVMs for each step), is there a way to merge them into a single view?
I'm not even sure if such a thing would be useful -- my hope would be that even though each run is relatively short and thus has a higher margin of error, in aggregate they'd average out and start to paint an accurate picture of the app's performance.

Re: merging snapshots
You cannot merge snapshots this way. Are you interested in CPU profiling results (sampling or tracing)?
As a workaround please consider export of the profiling results to external format for further processing:

You may write a script running the export for all snapshots and then somehow processing the results in an automated fashion.

Re: merging snapshots
Yes, I was primarily interested in the profiling results. That export sounds like it would do the trick, thanks!
