The use of Nagios in the Electrical Engineering Computer Lab of Udayana University

Note

This is my English translated assignment from my undergraduate Telecommunication System Reliability course regarding the Nagios application which can monitor the state of computer networks. Coincidently at that time I was also an assistant at computer laboratory and I got the opportunity to apply Nagios in the lab.

The author wishes to know the quality of Nagios according to the author’s personal view. For monitoring materials, 10 computers and 1 switch are provided in the computer laboratory, Electrical Engineering, Udayana University. In this experiment we will try to use Nagios to monitor 10 computers and 1 switch in Labkom, besides that, also monitor yourself…
