In this post, i will guide you on how to configure windows machine using and will be monitor via nagios server.
Steps:
1. Download the latest stable version of the NSClient++ addon from http://nsclient.org/nscp/downloads
2. There are two alternate ways to install the NSClient++ on windows server.
a) Double click the file if you downloaded the .msi installer. Set the NSClient to ‘nagiospassword‘.
b) Go to this URL and read the manual properly:
3. Modify the nagios.cfg and add server1.cfg line under windows.cfg line.
[root@server ~]# vi /etc/nagios/nagios.cfg
# Definitions for monitoring a Windows machine #cfg_file=/etc/nagios/objects/windows.cfg cfg_file=/etc/nagios/objects/server1.cfg
4. Make a copy the original windows.cfg config file and rename it to server1.cfg, which is the preferred server name.
[root@server ~]# cp /etc/nagios/objects/windows.cfg /etc/nagios/objects/server1.cfg
5. Define windows services that should be monitored.
[root@server ~]# vi /etc/nagios/objects/server1.cfg
# HOST DEFINITIONS
# Define a host for the Windows machine we'll be monitoring
# Change the host_name, alias, and address to fit your situation
define host{
use windows-server ; Inherit default values from a template
host_name server1 ; The name we're giving to this host
alias My Windows Server ; A longer name associated with the host
address 192.168.2.2 ; IP address of the host
}
# HOST GROUP DEFINITIONS
# Define a hostgroup for Windows machines
# All hosts that use the windows-server template will automatically be a member of this group
define hostgroup{
hostgroup_name windows-servers ; The name of the hostgroup
alias Windows Servers ; Long name of the group
}
# Create a service for monitoring the version of NSCLient++ that is installed
# Change the host_name to match the name of the host you defined above
define service{
use generic-service
host_name server1
service_description NSClient++ Version
check_command check_nt!CLIENTVERSION
}
# Create a service for monitoring the uptime of the server
# Change the host_name to match the name of the host you defined above
define service{
use generic-service
host_name server1
service_description Uptime
check_command check_nt!UPTIME
}
# Create a service for monitoring CPU load
# Change the host_name to match the name of the host you defined above
define service{
use generic-service
host_name server1
service_description CPU Load
check_command check_nt!CPULOAD!-l 5,80,90
}
# Create a service for monitoring memory usage
# Change the host_name to match the name of the host you defined above
define service{
use generic-service
host_name server1
service_description Memory Usage
check_command check_nt!MEMUSE!-w 80 -c 90
}
# Create a service for monitoring C:\ disk usage
# Change the host_name to match the name of the host you defined above
define service{
use generic-service
host_name server1
service_description C:\ Drive Space
check_command check_nt!USEDDISKSPACE!-l c -w 80 -c 90
}
# Create a service for monitoring the W3SVC service
# Change the host_name to match the name of the host you defined above
define service{
use generic-service
host_name server1
service_description W3SVC
check_command check_nt!SERVICESTATE!-d SHOWALL -l W3SVC
}
# Create a service for monitoring the Explorer.exe process
# Change the host_name to match the name of the host you defined above
define service{
use generic-service
host_name server1
service_description Explorer
check_command check_nt!PROCSTATE!-d SHOWALL -l Explorer.exe
}
6. Enable Password protection for NSClient. Set the password same as ‘2.a)‘.
# 'check_nt' command definition
define command{
command_name check_nt
command_line $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -s nagiospassword -v $ARG1$ $ARG2$
}
7. Verify the configuration
[root@server ~]# /usr/bin/nagios -v /etc/nagios/nagios.cfg
