  • Server Monitoring With munin And monit On Debian Squeeze

    debian Author: falkoTags: , Comments: 0

    Server Monitoring With munin And monit On Debian Squeeze In this article I will describe how you can monitor your Debian Squeeze 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, and a watchdog that ensures the availability of the monitored services.
