prstat -x

When looking with processes on your system, sometimes you ask your self “Who the heck started this process? Often it’s a process started by SMF as part of a service (or by a process started by SMF) but then the question is “Which service?”. prstat now got the new -x option. This shows for each process the FMRI of each process that was started as a part of an SMF service.

You have to scroll right to see the new output:

# prstat -x

This is really useful. I’m often (as in: almost always) using prstat in the microstate accounting mode with the -m option. However -m is one of the options that can’t be combined with -x.

root@solaris:~# prstat -xm
prstat: -x option cannot be used with -a, -t, -m, -v, -L or -H

Still this new option is super useful, because when i’m starting to use microstate accounting i’m already far beyond the topic of “Who started it?”
