check_procs returning wrong data

[Axel Amigo Arnold]

Hi Andreas, thank you for the response.

I already have the suid bit activated in the check_procs binary as you can
see here (I just copied the values of check_icmp)
-r-sr-sr-x

The user for this binary is root, and the group is nagios (just as
check_icmp), but I still can't access the total process list.
In the command definition, should I make something like this?

command[check_total_procs]=/usr/local/nagios/libexec/sudo check_procs -w
150 -c 200


Thanks!
