Examples:
 check_procs -w 2:2 -c 2:1024 -C portsentry
   Warning if not two processes with command name portsentry. Critical
   if < 2 or > 1024 processes

So that's almost what you are looking for. It will warn if there not two
processes named portsentry. You want that to go strait to critical
instead and check for "qdaemon"  --

  check_procs -c 2:2 -C qdaemon

testing it (using different process names that match my testing
criteria) --

$ ./check_procs -c 2:2 -C sendmail
PROCS OK: 2 processes with command name 'sendmail'

$ ./check_procs -c 2:2 -C sendmailbad
PROCS CRITICAL: 0 processes with command name 'sendmailbad' 

$ ./check_procs -c 2:2 -C init
PROCS CRITICAL: 1 process with command name 'init'

$ ./check_procs -c 2:2 -C nsca
PROCS CRITICAL: 14 processes with command name 'nsca'
