it's just a pity they're not compatible with Linux so I can't monitor or

I have a couple python scripts I've used for monitoring LSI/Avago
"Megaraid" controllers, these scripts run the 'megacli' command line
tool and parse the incredibly verbose output to generate a concise
summary, and another returns true/false to be used in an alert email
script run from a crontab entry. I lifted these scripts off the net,
and modified them a bit.
sample output, followed by the source for the two scripts.
