To add windows server in nagios:
1. Login to your windows server
2. Go to start --> Administrative tools --> Server Manager and install snmp service.
3. Go to service options from start --> administrative tools --> services
4. Right click SNMP service and select properties
5. Click security
6. Select "send authentication trap"
Under accepted community names
7. Click add
8. Select commuity rights -> Read only
Community name --> public
9. Click add
10.Select @ "accept SNMP packets from these hosts"
11. Add nagios server ip address
12.Click Apply --> ok
13.Restart snmp service
Note: If you see any by default ip then remove it.
go to nagios server and create hostname.cfg file and add services which you want to moniter
=====================
Now it’s time to define some object definitions in your Nagios configuration files in order to monitor the new Windows machine.
Open the windows.cfg file for editing.
vi /usr/local/nagios/etc/objects/windows.cfg
Add a new host definition for the Windows machine that you’re going to monitor. If this is the *first* Windows machine you’re monitoring, you can simply modify the sample host definition in windows.cfg. Change the host_name, alias, and address fields to appropriate values for the Windows box.
define host{
use windows-server ; Inherit default values from a Windows server template (make sure you keep this line!)
host_name winserver
alias My Windows Server
address 192.168.1.2
}
Replace “winserver” in the example definitions below with the name you specified in the host_name directive of the host definition you just added.
Now you can add some service definitions (to the same configuration file) in order to tell Nagios to monitor different aspects of the Windows machine. If this is the *first* Windows machine you’re monitoring, you can simply modify the sample service definitions in windows.cfg
Add the following service definition to monitor the version of the NSClient++ addon that is running on the Windows server. This is useful when it comes time to upgrade your Windows servers to a newer version of the addon, as you’ll be able to tell which Windows machines still need to be upgraded to the latest version of NSClient++.
define service{
use generic-service
host_name winserver
service_description NSClient++ Version
check_command check_nt!CLIENTVERSION
}
Add the following service definition to monitor the uptime of the Windows server.
define service{
use generic-service
host_name winserver
service_description Uptime
check_command check_nt!UPTIME
}
Add the following service definition to monitor the CPU utilization on the Windows server and generate a CRITICAL alert if the 5-minute CPU load is 90% or more or a WARNING alert if the 5-minute load is 80% or greater.
define service{
use generic-service
host_name winserver
service_description CPU Load
check_command check_nt!CPULOAD!-l 5,80,90
}
Add the following service definition to monitor memory usage on the Windows server and generate a CRITICAL alert if memory usage is 90% or more or a WARNING alert if memory usage is 80% or greater.
define service{
use generic-service
host_name winserver
service_description Memory Usage
check_command check_nt!MEMUSE!-w 80 -c 90
}
Add the following service definition to monitor usage of the C:\ drive on the Windows server and generate a CRITICAL alert if disk usage is 90% or more or a WARNING alert if disk usage is 80% or greater.
define service{
use generic-service
host_name winserver
service_description C:\ Drive Space
check_command check_nt!USEDDISKSPACE!-l c -w 80 -c 90
}
Add the following service definition to monitor the uptime of the Windows server.
define service{
use generic-service
host_name winserver
service_description Uptime
check_command check_nt!UPTIME
}
Add the following service definition to monitor the CPU utilization on the Windows server and generate a CRITICAL alert if the 5-minute CPU load is 90% or more or a WARNING alert if the 5-minute load is 80% or greater.
define service{
use generic-service
host_name winserver
service_description CPU Load
check_command check_nt!CPULOAD!-l 5,80,90
}
Add the following service definition to monitor memory usage on the Windows server and generate a CRITICAL alert if memory usage is 90% or more or a WARNING alert if memory usage is 80% or greater.
define service{
use generic-service
host_name winserver
service_description Memory Usage
check_command check_nt!MEMUSE!-w 80 -c 90
}
Add the following service definition to monitor usage of the C:\ drive on the Windows server and generate a CRITICAL alert if disk usage is 90% or more or a WARNING alert if disk usage is 80% or greater.
define service{
use generic-service
host_name winserver
service_description C:\ Drive Space
check_command check_nt!USEDDISKSPACE!-l c -w 80 -c 90
}
Password Protection
If you specified a password in the NSClient++ configuration file on the Windows machine, you’ll need to modify the check_nt command definition to include the password. Open the commands.cfg file for editing.
vi /usr/local/nagios/etc/commands.cfg
Change the definition of the check_nt command to include the “-s <PASSWORD>” argument (where PASSWORD is the password you specified on the Windows machine) like this:
define command{
command_name check_nt
command_line $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -s PASSWORD -v $ARG1$ $ARG2$
}
Also publicly available services that are provided by Windows machines (HTTP, FTP, POP3, etc.) can be monitored easily by following commands,
A simple service definition for monitoring the HTTP service on the remotehost machine might look like this:
define service{
use generic-service
host_name remotehost
service_description HTTP
check_command check_http
}
A simple service definition for monitoring the FTP server on remotehost would look like this:
define service{
use generic-service
host_name remotehost
service_description FTP
check_command check_ftp
}
A simple service definition for monitoring the SMTP server on remotehost would look like this:
define service{
use generic-service
host_name remotehost
service_description SMTP
check_command check_smtp
}
Save the file.
