Feature Request: PID Check

[azilber]

For version 1.1 (and up), it would be great to have something like:

proc.pid[<pid file>,<optional process name>]

Will a) check if the pid is a process and
b) if the optional process name exists, checks to make sure it matches the actual process name.

and

proc.pid.exists[<pid>,<optional process name>]

Same as above except you supply the pid. Not as usefull, but might be for some..

Why not creating a UserCommand and use `pgrep' from the procutils?

abi@kida:~$ pgrep firefox-bin
29928

anyway, monitoring a single pid may be quite useless because they
change anyway (after process restart), btw. on threaded programs
it doesnt make much sense.

Guys, is there a simple way to monitor process existence, knowing only the PID, not it's name. The issue is that I have couple of processes, which have the same names, but I need to monitor them all (not just existence of process_name, but existence of every process process_name. I have their PIDs, taken from pidfiles in /var/run directory.

Of course, it's no problem to use UserCommand and some simple script but maybe there is a better/different way.

OK, the solution with UserParameter is sufficient.

UserParameter=proc.num.XXX[*],ps acx | grep ^$(cat /var/run/XXX-"$1".pid) | wc -l
