NRPE: Unable to read output with check_connections plugin
- by Wlodzimierz
I'm using plugin which gives me warning or crtis with established connections.
If I run it on local machine it gives:
*root@graber:/usr/lib/nagios/plugins# ./check_connections -w 1 -c 5 -C sshd
CRITICAL Established connections: 6*
I know, I run as root. But:
Rights to the file:
root@graber:/usr/lib/nagios/plugins# ls -all check_connections
-rwxr-xr-x 1 nagios nagios 5459 2012-07-06 10:19 check_connections

log from remote:

Why is this happening? I'm out of ideas, I've searched google for 2 days now :)
