Bruce, I'm not sure that there's an existing check plugin that would do this (might be). I can say that "yes" you can do this, it's just a question of what you're willing to do. If I were to do this for our environment, I'd write a perl script that used the 'ps' command to look at the process and pull the 'pcpu' field (% cpu -- see the 'ps' man page) info for that process. I'd also use the Nagios::Plugin perl module to make the Nagios side easier and probably report the actual pcpu value as performance data suitable for graphing. You could then configure the an event on that service check. That essentially another script that gets called when the state changes on the check. This means it gets called anytime the state changes, including when it goes to an "OK" state so you need to have the script detect when it's called and potentially exit if it hasn't gone into a hard critical state (depending on what you want, actually). You can read up on events on the Nagios documentation.
