Hi list
Am getting the error:
CHECK_NRPE: No output returned from daemon on the nagios console.
Following setup:
Debug option on nrpe turned on.
Part of the nrpe.cfg file:
command[check_users]=/usr/local/nagios/libexec/check_users -w
5 -c 10
command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5
-c 30,25,20
command[check_disk1]=/usr/local/nagios/libexec/check_disk -w 20
-c 10 -p /dev/hda1
command[check_disk2]=/usr/local/nagios/libexec/check_disk -w 20
-c 10 -p /dev/hdb1
command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs
-w 5 -c 10 -s Z
command[check_total_procs]=/usr/local/nagios/libexec/check_procs
-w 150 -c 200
Output /var/log/messages when connection from nagios host connects:

3 and output:
Jan 23 14:18:16 xxx nrpe[xxxx]: Return Code: 3, Output:
On monitored host manually run the ./check_users command as nagios
user:
When run as ./check_users
results in
== blank line ==
== blank line ==
Usage: check_users -w <users> -c <users>
When run as ./check_users -w 5 -c 10
results in
USERS OK - 4 users currently logged in |users=4;5;10;0
To me it seems that the nrpe program, when triggered via the ./check_nrpe
command on the nagios host, is not parsing the config file correctly
and is not attaching the command options correctly.
Reading the source, the Running command: line of the log file should
have the switches included.
I have tried to quote "" the command in the config file but this
did not work.
Any thoughts?
nagios v2.0rc2 Jan 10 2006
and
nrpe v2.2 - 01/22/2006
Cheers
Jim
