[Pkg-nagios-devel] Bug#546195: Bug#546195: nagios-plugins-basic: using check: /usr/lib/nagios/plugins/check_procs ... -C X does not work

[Juhani Puska]

This has been collected from out testlab (LTSP), command output attacheched,
Interesting row is here:

Ss+      0  4165  4163  16668 10468  0.1 Xorg            X -auth 
/var/run/ldm-xauth-LABLN4123 -br -noreset -depth 16 vt7 :7

parameter -C X does not recognize it. I have also found other process (amavisd) 
which does not filtered by name:

PROCS CRITICAL: 0 processes with command name 'amavisd'


I have't look (no time at the moment) the c-code, but both of these are 
multirunning processes, like here amavisd:

  1583 ?        Ss     0:01 amavisd (master)
30939 ?        S      0:00  \_ amavisd (ch7-avail)
31005 ?        S      0:00  \_ amavisd (ch8-avail)
32474 ?        S      0:00  \_ amavisd (ch7-avail)
   427 ?        S      0:01  \_ amavisd (ch6-avail)
  1509 ?        S      0:00  \_ amavisd (ch2-avail)

X is running same, X is the root process for other processes, like session 
manager etc.

It is easy to check out the problem on whatever Linux/X-machine.
