Hi,
we noticed that after installing one of the new debian.org machines with
squeeze some of our remote nrpe checks would fail.
In particular
| /usr/lib/nagios/plugins/check_procs -w 1:1 -c 1:1 -u root -C monit -a
'/usr/sbin/monit -d 300 -I -c /etc/monit/monitrc -s /var/lib/monit/monit.state'
| PROCS OK: 1 process with UID = 0 (root), command name 'monit', args
'/usr/sbin/monit -d 300 -I -c /etc/monit/monitrc -s /var/lib/monit/monit.state'
when run locally would succeed, but running via NRPE would fail:
| wea...@tchaikovsky:~$ /usr/lib/nagios/plugins/check_nrpe -H 82.195.75.101 -n
-c dsa_ps_monit
| PROCS CRITICAL: 0 processes with UID = 0 (root), command name 'monit', args
'/usr/sbin/monit -d 300 -I -c /etc/monit/monitrc -s /var/lib/monit/monit.state'
until we restarted nrped on the server. After a reboot it started
failing again.
Stracing the nrpe process and its children suggested that the ps output
lines get truncated at one point:
} [pid 12235] <... read resumed> " ....
} ...tty 38400 tty6\nSs 0 1093 1 31888 2292 0.0 01:19:56 monit
/usr/sbin/monit -d 300 -I -c /etc/monit/monitrc -s /var/lib/mon\nS
0 1247 2.....
We noticed that ps is run with only one w argument passed to it.
Sure enough, patching the debian source package to pass two w's to ps
fixed the issue:
| wea...@tchaikovsky:~$ /usr/lib/nagios/plugins/check_nrpe -H 82.195.75.101 -n
-c dsa_ps_monit
| PROCS OK: 1 process with UID = 0 (root), command name 'monit', args
'/usr/sbin/monit -d 300 -I -c /etc/monit/monitrc -s /var/lib/monit/monit.state'
