Hi Jason,
Here is the NRPE related configs...
*checkcommands.cfg
define command{
command_name check_nrpe_disk
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c check_disk1
}
*services.cfg
define service {
use generic-service
host_name somesystem
service_description DISK
is_volatile 0
check_period 24x7
max_check_attempts 3
normal_check_interval 5
retry_check_interval 1
contact_groups somegroup
notification_interval 120
notification_period 24x7
notification_options c,r
check_command check_nrpe_disk
}
*nrpe.cfg
server_port=5666
nrpe_user=nagios
nrpe_group=nagios
dont_blame_nrpe=0
debug=1
command_timeout=60
command[check_disk1]=/usr/sbin/check_disk -w 20% -c 10%
*Doing things manually from the nagios server
Issuing...
%./check_nrpe -H somesystem -c check_disk1
Yeilds...
NRPE: Unable to read output
Changing the disk to one that does not exist...
%./check_nrpe -H somesystem -c check_disk2
Yeilds...
NRPE: Command 'check_disk2' not defined
This tells me that the daemon is up and running and that information is
flowing back and forth.
The the daemon does start up and is listening on 5666...
%netstat -na | grep 5666
tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN
tcp 0 0 192.168.161.2:5666 192.168.161.221:59929 TIME_WAIT
and ps -ef | grep nrpe
nagios 26845 1 0 14:51 ? 00:00:00 nrpe -c /etc/nrpe.cfg -d
Thanks for the help and let me know what else you need...
John

be sitting next to you saying, "Damn...that was fun!"
