I am a student and we need to install Nagios on a CentOS 7 server. At the end we should observe CPU, memory, and disk usage of the server, where the Nagios is installed on. Firstly i tried with Nagios Core, but i didn't get the CPU usage. So i decided to install the Nagios XI.
Now i can see for example the actual CPU usage but is it also possible to get the usage of CPU, memory, and disk for the last 8 hours?
I have only one CentOS 7 server (localhost) and need to observe himself (so the Nagios is only to get the graph for the last 8 hours). Is this possible
Thanks in advance for help!
Best regards
