I am looking for a good server monitoring script for Ubunti server that will detect and restart services such as MySQL, httpd, FTP etc. if they go down.

Is there any good scripts that can do this?

webmin...oops need ten characters...um, webmin

monit (http://mmonit.com/monit/)

sim (http://www.rfxn.com/projects/system-integrity-monitor/)

Thank you. I ended up installing SIM.
