Server Administration: automatically restarting services

[Darin Perusich]

any easy way to accomplish this is to write cron job which which runs 
every 5 minutes, checks for the services and starts if necessary. 
sysadmin magazine had an article on a year or two ago called keeping 
your services up with viagara, or something like that.

i would start off by monitoring your server with a monitoring system 
like BigSister or BigBrother. i've been using bigbrother for like 5+ 
years to monitor my systems and i'd stronly recommend it. i've reciently 
started using bigsister and i like it, integrates nicely with bigbrother 
and it's gpl'd.
