Check_disk alerts

[Siddharth Hegde]

Hi All,

I have configured 2 Ubuntu servers, one for Nagios and one for nrpe. I want to configure disk space alerts for a partition /dev/xvda1. But I am getting alerts for all partitions.

Requesting help to configure check_disk only to alert /dev/xvda1 and not others.

host.cfg

Code: Select all

define service{
        use                             generic-service
        host_name                      client
        service_description             Disk Spaces
        check_command                   check_nrpe!check_disk
         contact_groups                  Monitoring
        check_interval                  1
        }

nrpe.cfg in client-server

Code: Select all

command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/xvda1
command[check_disk]=/usr/local/nagios/libexec/check_disk -w 20% -c 15% -A -I '/dev/xvda1'

commands.cfg

Code: Select all

define command{
    command_name    check_disk
    command_line    $USER1$/check_nrpe -H '$HOSTADDRESS$' -t 30 -c check_disk
     }

I have uploaded the server disk (df -h) screenshot in the attachment.

Please let me know if any other information is required to further analyze this issue.
