Hi,

For disk check up try out below procedure will help you to configure /home partition monitor setup.

Step 1  : Edit /etc/nagios/checkcommands.cfg:

 

# 'check_local_disk' command definition

 

define command{

                                command_name    check_local_disk

                                command_line    $USER1$/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$

                                                }

 

Step 2 : open up /etc/nagios/commands.cfg

# Command used to check disk space usage on local partitions

 

define command{

                                command_name   check_local_disk

                                command_line   $USER1$/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$

                                                }

 

Note : commands.cfg entry can be copied directly from checkcommands.cfg

 

Step 3 : edit /etc/nagios/services-servers.cfg

 

# Define a service to check the disk space of the root partition

# on the local machine.  Warning if < 20% free, critical if

# < 10% free space on partition.

 

define service{

        use                             generic-service         ; Name of service template to use

        host_name                                 hostname.com

        service_description                Home Partition

        is_volatile                                    0

        check_period                            24x7

        max_check_attempts            4

        normal_check_interval         5

        retry_check_interval            1

        contact_groups                     admins

   notification_options                    w,u,c,r

        notification_interval           960

        notification_period             24x7

   check_command         check_local_disk!20%!10%!/home

        }

 

Step : 4 Try to test your configuration

#nagios -v nagios.cfg

 

Step 5 : Restart Nagios

                #/etc/init.d/nagios restart
