# Parameters:

# Description:
#	Run vmstat for an hour at 2 minute intervals.
#
#	It assumes that the script and data both live in /home/Performance.
#	To use this properly, add a crontab entry which looks like :
#
#	0 * * * * /home/Performance/bin/Perf.sh
#
#	i.e. start on the hour, every hour. The script itself runs for an hour.
#	You'll see one file per hour in the data directory for the full month,
#	a new directory automatically being created at the start of the new month.
# Maintenance:
