Shell Programming and Scripting

Hi,

I need to find out the gigabytes/hour growth in filesystem.

i am using df command for finding the filesystem size and free space every hour. But how can i find the increase in size per hour?

Do i have to store the last hour entries in a file and comapre with the recent size and get the difference.? Or is there a way to determine the increase?

Thanks in advance

you can check out the I/O input out put. iostat

thank you..

i am new to shell scripting...

can i use iostat for getting similar result for each mount point associated with the filesystem

Alos can i change the report to show only the rate of write per hour?

also when i do df -m |awk '{print $5 " " $2}

i am getting the megabytes occupied in each of the mount point

/u02 8717924
/u01 5562586

after one hour the space is increased by few bytes

i want to get the increase in megabytes/hour for each of these mounts -- /u01, /u02
report shpould be generated every hour for one week...
