linuxhelp:~ # systemctl restart nagios
linuxhelp:~ # systemctl restart apache2

Now move to your windows machine and download the ncpa plugin for windows from Nagios official website

Next move to Nagios server and go to /usr/local/nagios/etc path location

linuxhelp:~ # cd /usr/local/nagios/etc
linuxhelp: /usr/local/nagios/etc # vim nagios.cfg
