args is not the same than command, maybe i misunderstood it as i check it.

but real problem (in my sense) is on openbsd 3.5:
$ /usr/local/libexec/nagios/check_procs -C sshd
PROCS OK: 3 processes with command name 'sshd'
$ /usr/local/libexec/nagios/check_procs -a sshd
PROCS OK: 3 processes with args 'sshd'
$ ps -axu |grep sshd
root       143  0.0  0.2   288   808 ??  Is    24Sep04    0:03.60
/usr/sbin/sshd
root     28833  0.0  0.5   384  1916 ??  Is     6:19AM    0:00.12 sshd:
touche [priv] (sshd)
touche   20312  0.0  0.3   416  1380 ??  S      6:19AM    0:00.07 sshd:
touche at ttyp0 (sshd)
touche   32454  0.0  0.0    96   180 p6  D+     6:19AM    0:00.00 grep sshd

and on my whitebox linux nothing with -C sshd

$ /opt/nagios/libexec/check_procs -C sshd
PROCS OK: 0 processes with command name 'sshd'
$ /opt/nagios/libexec/check_procs -a sshd
PROCS OK: 6 processes with args 'sshd'
/opt/nagios/libexec/check_procs -a sshd
$ ps axu|grep sshd

and an extra: grep is count with -a (and not on openbsd)
