What is NSClient++ :-
NSClient++ a elementary withal powerful in addition to flexible monitoring daemon. It was built for Nagios/Icinga/Naemon, simply zippo inwards the daemon is Nagios/Icinga specific in addition to it tin flame in addition to is used inwards many other scenarios where yous desire to receive/distribute banking concern check metrics. It is alone possible to utilisation it stand upwards lone besides equally the kernel monitoring organization though that is non recommended equally it is rather limited.How to Install NSClient++ :-
Download NSClient++ from below mentioned link :
Installation Steps :-
Run Downloaded File NSClient++
The installation has been finished Successfully.
Nagios Core Side Configuration :-
We request login to Nagios kernel server using putty.
Step 1:-
Create Influenza A virus subtype H5N1 fundamental directory to proceed all the Windows.cfg file using below command.
root@WPT: # mkdir /usr/local/nagios/etc/windows
Now Copy Windows template amongst the hostname nosotros are going to add. In my illustration I k adding Host ISHWS69. Use below ascendancy to Copy template.
root@WPT: # cp /usr/local/nagios/etc/objects/windows.cfg /usr/local/nagios/etc/windows/ishws69.cfg
Step 2:-
Now brand highlighted changes into the .cfg file equally follow:
root@WPT: # vi /usr/local/nagios/etc/windows/ishws69.cfg ############################################################################### # WINDOWS.CFG - SAMPLE CONFIG FILE FOR MONITORING Influenza A virus subtype H5N1 WINDOWS MACHINE # # # NOTES: This config file assumes that yous are using the sample configuration # files that larn installed amongst the Nagios quickstart guide. # ############################################################################### ############################################################################### ############################################################################### # # HOST DEFINITIONS # ############################################################################### ############################################################################### # Define a host for the Windows machine we'll live on monitoring # Change the host_name, alias, in addition to address to fit your province of affairs define host{ utilisation windows-server ; Inherit default values from a template host_name ishws69 ; The shout out we're giving to this host alias My Windows Server ; Influenza A virus subtype H5N1 longer shout out associated amongst the host address 10.0.1.107 ; IP address of the host } ############################################################################### ############################################################################### # # HOST GROUP DEFINITIONS # ############################################################################### ############################################################################### # Define a hostgroup for Windows machines # All hosts that utilisation the windows-server template volition automatically live on a fellow member of this grouping define hostgroup{ hostgroup_name windows-servers ; The shout out of the hostgroup alias Windows Servers ; Long shout out of the grouping } ############################################################################### ############################################################################### # # SERVICE DEFINITIONS # ############################################################################### ############################################################################### # Create a service for monitoring the version of NSCLient++ that is installed # Change the host_name to gibe the shout out of the host yous defined inwards a higher house define service{ utilisation generic-service host_name ishws69 service_description NSClient++ Version check_command check_nt!CLIENTVERSION } # Create a service for monitoring the uptime of the server # Change the host_name to gibe the shout out of the host yous defined inwards a higher house define service{ utilisation generic-service host_name ishws69 service_description Uptime check_command check_nt!UPTIME } # Create a service for monitoring CPU charge # Change the host_name to gibe the shout out of the host yous defined inwards a higher house define service{ utilisation generic-service host_name ishws69 service_description CPU Load check_command check_nt!CPULOAD!-l 5,80,90 } # Create a service for monitoring retentiveness usage # Change the host_name to gibe the shout out of the host yous defined inwards a higher house define service{ utilisation generic-service host_name ishws69 service_description Memory Usage check_command check_nt!MEMUSE!-w eighty -c ninety } # Create a service for monitoring C:\ disk usage # Change the host_name to gibe the shout out of the host yous defined inwards a higher house define service{ utilisation generic-service host_name ishws69 service_description C:\ Drive Space check_command check_nt!USEDDISKSPACE!-l c -w eighty -c ninety } # Create a service for monitoring the W3SVC service # Change the host_name to gibe the shout out of the host yous defined inwards a higher house define service{ utilisation generic-service host_name ishws69 service_description W3SVC check_command check_nt!SERVICESTATE!-d SHOWALL -l W3SVC } Save in addition to Exit from the file.
Step 3:- Add ishws69.cfg file path into nagios.cfg file then that Nagios Core tin flame start reading this file.
Open Nagios.cfg configuration file using below command.
root@WPT: # vi /usr/local/nagios/etc/nagios.cfg Now add together the highlighted line into conf file.
############################################################################## # # NAGIOS.CFG - Sample Main Config File for Nagios 4.2.3 # # Read the documentation for to a greater extent than information on this configuration # file.

Step 4:- Check Nagios Core configuration file for whatever error. Using below command.
root@WPT: # /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg Nagios Core 4.2.3 Copyright (c) 2009-present Nagios Core Development Team in addition to Community Contributors Copyright (c) 1999-2009 Ethan Galstad Last Modified: 11-21-2016 License: GPL Website: https://www.nagios.org Reading configuration data... Read primary config file okay... Read object config files okay... Running pre-flight banking concern check on configuration data... Checking objects... Checked 8 services. Checked 1 hosts. Checked 1 host groups. Checked 0 service groups. Checked 1 contacts. Checked 1 contact groups. Checked 24 commands. Checked v fourth dimension periods. Checked 0 host escalations.

root@WPT: # /etc/init.d/nagios restart [ ok ] Restarting nagios (via systemctl): nagios.service. Now Access Nagios through Browser in addition to banking concern check newly added host should live on there.
!!!Cheers!!!
