Look in the reports section of the NetWorker Management Console. Look at the
Devices/Drive Utilization report. That report gives a nice visual depiction
of sessions on each device over time.

Actually, I was only answering the "why would anyone want this information"
question in the previous post.  We have tools and scripts which gather what
we need to tune our environment appropriately - taking into account the
information that you mentioned (backup windows, long running clients, OS and
network restrictions) and including the number of sessions running per
drive.  Now, if we only had an unlimited budget to spend on our
environment.... :-)

Hello,
I don't think it would be easy for us ( me) to guess what is your
environment like ? i.e Do you use DDS, VTL, Dedupe ? clones ? 
What kind of data do you backup, what os, how much data and how long does it
take currently to backup , which clients are taking the longest ? 
Not to even get into hardware configurations , it is difficult to imagine
what is the best approach for you without this info. 
One thing to look for is what is your backup window and are you
accomplishing it now, have you done a proper load balancing of jobs, pools,
devices and clients ? 
If you are finishing the backups in reasonable time without any of the
systems being stressed then you may not need to make wholesale changes. 
If you are having problems, find out which groups\clients take the longest,
then analyze  the backup process for this problem servers\nodes and make one
change at a time ( Can you use GB network, can you implement additional SN,
Could you archive the data, lan free, ndmp  are some example of what you can
look at). 
Depending of the issues you may have, there is going to be multiple
approaches to resolve them within the current backup framework and\or with
additional technologies might benefit you. 
HTH

We've also chased after this information for performance reasons.  We have
10 tape drives, two storage nodes and 3 different tape pools.  We want this
information so we can tune our configuration.  For example, do we have
enough tape drives dedicated to each tape pool on each storage node?
Overall, does each storage node have enough tape drives allocated to it?  

If there are LOTS of sessions writing to a single drive for 5 minutes,
that's ok for restores.  The 5 minute backups are fairly small and will
recover quickly regardless of horrible multi-threading.  If, however, there
are LOTS of sessions going to a tape drive for hours, then we need to solve
that problem so that we have a reasonable restore speed.
Having this information can help to justify spending money to expand or
upgrade the backup environment.

Thanks.
Teresa

I can't understand of what use this data would be... If it is possible to
capture this data in text format, what could it be used for ? You would
simply be getting a snapshot in time of the current save sessions running at
that moment. Come back five minutes later, you now have a different picture
compared to what it was before. The number of current sessions is constantly
in a state of change, as sessions complete, new ones start, until the
work-list of all save-sets for the entire group and all its clients is
exhausted.... Then the group completes and triggers a savegroup completion
event... 

Who wants this and for what purpose ???
