How To Monitor Windows Memory Usage, Diskspace, CPU Load and Uptime From Nagios

We will trying to monitor Windows Memory Usage, Diskspace, CPU Load and Uptime From Nagios.

First we need to have a nagios up and running smoothly.
Please follow up this url to install nagios http://www.nagios.org

Next we also need a windows nagios agent.
Download windows nagios agent from this url http://nsclient.ready2run.nl/download/nsclient_201.zip

Install nagios agent / nsclient to your windows server/client.

# Copy pNSClient.exe, pdh.dll, psapi.dll and counters.defs in any directory on the machine you want to monitor. ie. (c:\nsclient).
# Open a dos prompt in the installation directory
# Run the following command : >pNSClient.exe /install
# Type 'net start nsclient' on the command line or start the service 'Nagios Agent' in the services applet of the control panel.

Open up a firewall port 1248TCP for nagios agent in your windows client/server

On the Unix machine / Nagios Server

1. Copy the file 'check_nt' under the libexec folder of Nagios.
2. Add the following lines to the commands.cfg file:

# NSClient basic return types

command[check_nt_disk]=$USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v USEDDISKSPACE -l $ARG1$ -w $ARG2$ -c $ARG3$
command[check_nt_cpuload]=$USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v CPULOAD -l $ARG1$
command[check_nt_uptime]=$USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v UPTIME
command[check_nt_clientversion]=$USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v CLIENTVERSION
command[check_nt_process]=$USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v PROCSTATE -l $ARG1$
command[check_nt_service]=$USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v SERVICESTATE -l $ARG1$
command[check_nt_memuse]=$USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v MEMUSE -w $ARG1$ -c $ARG2$
command[check_nt_fileage]=$USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v FILEAGE –l $ARG1$ -w $ARG2$ -c $ARG3$

# Custom counters (one per required counter, or define a generic one and use $ARG1$ to specify the requested counter).

command[check_nt_pagingfile]=$USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v COUNTER -l "\\Paging File(_Total)\\%% Usage","Paging File usage is %.2f %%" -w $ARG1$ -c $AR

Add your server to monitor diskspace, memusage, cpu load ,etc and Restart your nagios services.
