NRPE Warning threshold must be a positive integer
- by Frida
OS: Ubuntu 12.10 Server 64bits
I've installed Icinga, with ido2db, pnp4nagios and icinga-web (last release, following the instruction given in the documentation, installation with apt, etc).
I am using icinga-web to monitor my hosts. For the moment, I have just my localhost, and all is perfect.
I am trying to add a host and monitor it with NRPE (version 2.12):
root@server:/etc/icinga# /usr/lib/nagios/plugins/check_nrpe -H client
NRPE v2.12
The configuration looks good.
I've created a file in /etc/icinga/objects/client.cfg as below on the server:
root@server:/etc/icinga/objects# cat client.cfg
define host{
use generic-host ; Name of host template to use
host_name client
alias client.toto
address xx.xx.xx.xx
}
# Service Definitions
define service{
use generic-service
host_name client
service_description CPU Load
check_command check_nrpe_1arg!check_load
}
define service{
use generic-service
host_name client
service_description Number of Users
check_command check_nrpe_1arg!check_users
}
And add in my /etc/icinga/commands.cfg:
# this command runs a program $ARG1$ with no arguments
define command {
command_name check_nrpe
command_line /usr/lib/nagios/plugins/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a $ARG2$
}
# this command runs a program $ARG1$ with no arguments
define command {
command_name check_nrpe_1arg
command_line /usr/lib/nagios/plugins/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
But it does not work.
These are the logs from the client:

Have you any ideas?
