I have a working Nagios setup where I e.g. monitor disk usage through the NRPE daemon without parsing arguments through NRPE for security reasons. So I know that NRPE works.
Now I would like to check NFS using the check_mountpoints plugin, but I get
NRPE: Unable to read output
On Nagios Monitor host I have set
define command {
command_name check_mountpoints
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -p 5666 -c check_mountpoints
}
define service {
use generic-service
name check_mountpoints
host_name example.com
service_description Check_mountpoints for nfs cifs davfs
check_command check_nrpe!check_mountpoints
contact_groups linux-admins
}
On the remote host have I set
command[check_mountpoints]=/usr/lib/nagios/plugins/check_mountpoints.sh /nas1/home
To verify that the correct arguments have been given the command outputs this
[root@nas ~]# /usr/lib/nagios/plugins/check_mountpoints.sh /nas1/home
OK: all mounts were found ( /nas1/home)
[root@nas ~]#
And both Nagios monitor host and remote host have a working NRPE daemon running.
Question
How do I debug something like this?
check_mountpoints.sh
were750
, which had to be755
.
