I think there are some concepts getting mixed up here. I know some of this might be obvious, but sometimes it's good to go back to basics.

check_disk_snmp is a plugin that allows you to check disk usage via SNMP. This is helpful for monitoring remote systems that do not have an agent (like nrpe).

NRPE is for agent based checking, it allows more flexibility by allowing you to run scripts (unlike SNMP). It also can add an administrative overhead because you need to install / configure the agent on each host your are monitoring.

On my nagios core server

[root@sov-srv-negios01 ~]# su - nagios
[nagios@sov-srv-negios01 ~]$ /usr/local/nagios/libexec/check_nrpe -H 10.128.132.17 -c check_sftp
DISK OK - free space: /sftp 46696 MB (99% inode=99%);| /sftp=183MB;39510;44449;0;49388
[nagios@sov-srv-negios01 ~]$

On my monitoring client

nrpe.cfg file

command[check_sftp]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /sftp
command[check_disk_snmp]=/usr/local/nagios/libexec/check_disk_snmp -t localhost -w 85% -c 95% -p public -x '^/' -i '/sftp'
[nagios@virginsftp01 ~]$

[nagios@ginsftp01 ~]$ /usr/local/nagios/libexec/check_disk_snmp -t 127.0.0.1 -w '80' -c '90' -p 'public' -x '^/' -i '/sftp'
DISK OK - free space: /sftp 51.6gb;
[nagios@ginsftp01 ~]$

So when you are running this command from your Nagios host:
/usr/local/nagios/libexec/check_nrpe -H 10.128.132.17 -c check_sftp
It is being executed on the monitoring client. And your result shows this is working.

Assuming your command definition is:

Code: Select all

define command{
        command_name    check_nrpe
        command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -t 30 -c $ARG1$ $ARG2$
        }

Then the service definition for that would be something like:

Code: Select all

define service{
        use                     generic-service
        host_name               10.128.132.17
        service_description     check_sftp
        check_command           check_nrpe!check_sftp
        }

Question: Is this what you are after?

If so I would stop trying to use check_disk_snmp. Especially above where you are trying to execute it via check_nrpe, this is double handling.

Hi Sanjay

Which Linux distribution are you using on Nagios server and client.

I tested it on rhel5.4 and centos 6.5 but no issue

I used this plugin http://exchange.nagios.org/directory/Pl ... mp/details


[nagios@srv01~]$ /usr/local/nagios/libexec/check_disk_snmp -t 10.94.64.111 -w 85% -c 95% -p public -x '^/' -i '/export'
DISK OK - [25% full,23.8gb free on /export]

check_disk_snmp.PNG (3.43 KiB) Viewed 4681 times

Did you change in plugin ?
Because there is difference in plugin output between your side and mine otherwise you are using another plugin.

--DISK OK - free space: /sftp 51.6gb;
--DISK OK - [25% full,23.8gb free on /export]

Finally its working

My configuration are like this

Commands.cfg

define command{
command_name check_nrpe
command_line /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}


Host.cfg.

define service{
use generic-service ; Name of service template to use
host_name virginsftp01
service_description SFTP Partition
check_command check_nrpe!check_sftp
}

Hi Rajesh

I am using Centos 6.5 on both client and server and its working now.

Thanks for suggestion
