Ready to be published? LXer is read by around 350,000 individuals each month, and is an excellent place for you to publish your ideas, thoughts, reviews, complaints, etc. Do you have something to say to the Linux community?
Nagios is an open source software for system and network monitoring. Nagios can monitor the activity of a host and its services, and provides a warning/alert if something bad happens on the server. Nagios can run on Linux operating systems. At this time I will use Ubuntu 16.04 for the installation.
