    Author: ovisTags: Comments: 12

    Network Monitoring With Zabbix Zabbix has the capability to monitor just a about any event on your network from network traffic to how many papers are left in your printer. It produces really cool grahps. In this howto we install software that has an agent and a server side. The goal is to end up with a setup that has a nice web interface that you can show off to your boss ;) It's a great open source tool that lets you know what's out there.

    Server Monitoring With munin And monit In this article I will describe how to monitor your server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.
