MySQL Create a list of load averages

`/proc/loadavg` give me three indicators of how much work
the system has done during the last 1, 5 & 15 minutes.

How can i get a list of load averages
that each averaged over the last minute for 10 minutes?

Code:
#!/bin/bash
for i in 1 2 3 4 5 6 7 8 9 10
do
     cat /proc/loadavg
     sleep 60
done > /tmp/t.lis
awk '{ sum +=$1; print $1 } END {print sum/NF}'  /tmp/t.lis > avg.lis
# use the avg variable

If you want the load averages from now onwards, you can try:

pandu$ sar -u <time-diff between samples in seconds> <no. of averages>

ex.
Code:
 
$ sar -u 4 2
