Xymon is a web-based system – designed to run on Unix-based systems – that allows you to dive deep into the configuration, performance and real-time statistics of your networking environment.
It offers monitoring capabilities with historical data, reporting and performance graphsOnce you’ve installed Xymon, the first place you need to go is the hosts.cfg file to add the hosts that you are going to monitor.
Here, you add information such as the host IP address, the network services to be monitored, what URLs to check, and so on.
When you launch the Xymon Web UI, the main page lists the systems and services being monitored by Xymon. Clicking on each system or service allows you to bring up status information about a particular host and then drill down to view specific information such as CPU utilization, memory consumption, RAID status, etc..
