Not sure about drilling down, there might be a plugin for it, but dstat was really useful for me recently in troubleshooting this type of problem. http://dag.wieers.com/home-made/dstat/ yeah it looks like dstat_app plugin might do what you want... dave
Dave, Thanks for the tip. I ran 'apt-get install dstat' on my ubuntu system which installed dstat and a bunch of plugins. Still getting my bearings, but your second tip about the app plugin was also useful. I'm running something like: dstat -dplmy --nocolor -M app where '-M app' includes this plugin. The plugin is poking around in /proc/<pid>/stat so my answer might be lurking in there somewhere. Cheers, Daniel Daniel B. wrote:
