I use MONIT. For a few servers it's ok. For more than 3 not. If you wish to see what happents on your server you have to open it in your browser, 1 screen for every server. See http://www.howtoforge.com/server_monitoring_monit_munin for details.

I gonna test Bixdata because it seems more made for monitoring more servers. See http://www.howtoforge.com/server_monitoring_bixdata for details. I have no experience with Bixdata.

You can also try Zabbix, Nagios, and Cacti.
For Zabbix, we have a tutorial: http://www.howtoforge.com/zabbix_network_monitoring
