Server Monitoring With munin And monit On Debian Etch
In this article I will describe how you can monitor your Debian Etch 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 let 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.

Custom Monitoring MySQL and SNMP with BixData
With BixData you can monitor your servers as well as VMware and Xen. BixData includes pre-built plugins for things like CPU, Memory, Disk, etc. but any good monitoring tool needs to be customizable. BixData includes the basic ability to run scripts and record their exit values, similar to Nagios Plugins. BixData 2.7 adds support for importing data in more complex formats. This allows you to monitor almost anything. I'll go through the steps showing you how to monitor MySQL locally where an agent is installed and then the steps to monitor a device remotely through SNMP. The advantage of BixData is that any data available through a BixAgent works with the standard tools such as the situation room, scoreboards, notifications and the reporting system. All data are stored in standard SQL tables and are easily accessible.
