[Nagiosplug-devel] check_procs problem

[Voon, Ton]

I had a problem on Mac OS X (which is based on FreeBSD) where 

ps waxco 'state uid ppid command command'

would only give one command column. Patch 652074 which I've put on
sourceforge sets the command for MacOSX to be

ps waxo 'state uid ppid ucomm command'

instead. Maybe something similar is happening for you?

Quoting Subhendu Ghosh (sghosh at sghosh.org):

Did you mean egrep -v ?  If so, it only gives the command name, rather
than all the arguments, too (this is on FreeBSD 4.6).

It looks like the problem might be the "c" option to ps.  Removing it
gives me the entire command line.  Of course that's not really what we
want either, because it makes it non-trivial to match the -C parameter
to check_procs.

It looks like it may be necessary to run ps more than once to handle
the "check_procs -C cmd -a args"; once to match "cmd" and then again
once per process to match "args".  Perhaps this already happens.
Unfortunately the machine I have nagios installed on is having a fit
at the moment.  It's also 60 miles away and it's snowing, so I won't
be going there to fix it today.  I'll look into this a bit further once
I can get access to the machine again.
