Description

Top

This is a generic script that I send to customers.  I have them make 
this a cron job.  The frequency I have the customer run this depending on
what customer's problem is. 

Update, not original author:

What's needed is data covering both good and
bad performance time periods if possible, and a README from the customer
saying what time the problem was bad, so that we can compare -- it's the
comparison of the changes in the data with the customer's perceived performance
issues that is important.

Alternatively, if the problem is too fine-grained to capture with snapshots
every 5 minutes or so, such as a problem that can be triggered by a command
but only lasts 1-7 minutes, this can be used instead.  It's run by hand,
from the command line, with # of minutes TOTAL to continue capturing data
as the command-line argument:
