average backup time statistics script for a particular node or all nodes

Hi to all,

I have been trying to figure out a script which will display the average backup time for a node and/or for all nodes
on a tsm v6.x server for a given number of days so that I can see if the backups for a particular node is taking longer.

I plan to use the output overtime to see where a client node may be getting so long that it's interfering with the users
window etc.

I have looked through the scripts in this forum and found some great scripts but not with some type of averaging
available?

Is there any free 3rd party reporting apps that would do the job?

Best Regards,
Bob...
