<br />
Login to server<br />
<br />
• cd /home/Nagios/bin/<br />
<br />
• ls<br />
<br />
We can see here different file in red and purple color<br />
<br />
- Purple color file – Already installed plugins<br />
<br />
- Red color file – We have configured that<br />
<br />
<br />
Also we have created symlink for purple color files, which have already installed plugins.<br />
<br />
Purpose of symlink is, if installed some server updates or restarts server, then also we don’t have replace that plugins again at /home/Nagios/bin/<br />
<br />
If we have to check OS release, then run below command <br />
<br />
• ./check_os_release.py<br />
<br />
<br />
