There are different ways. Here are some simple.
Maybe describing which kind of monitoring you think
about may pop-up other solutions.
1) gathering ssid being staged from disk to tape :
Mminfo -q volume=Disk.001,copies=3 -r ssid,client,name
Why copies = 3 ? Simple : copy is related to ssid.
1 copy on writable disk.001 volume,
1 copy on read-only disk.001.ro volume,
1 begin staged.
-> you know which ssid is being staged
2) another way is to gather list of ssid before staging
With mminfo -q volume=disk.001 -r ssid,client,name
During nsrstage, compare ssid from that list with new
Mminfo so you can get how many ssid have been staged and
Use new mminfo output as reference for following one
3) if no new backup are dumped to disk during staging,
just mminfo -q volume=disk.001 -r ssid,client,name
should list remaining list to stage.
4) If you want to monitor how many data still must be
staged : mminfo -q volume=disk.001 -r written
You will get remaining data on volume. (faster than
summing each ssid's size.
PS : It is always safe to run "nsrstage -C -V <volume>"
after nsrstage, this to clean/remove file/advfile devices
from ghosts ssids.

Subject: [Networker] monitoring staging operations
Hi everyone,
We're implementing a disk to disk to tape backup. So, I've got the advanced
file type devices set up, I've got the mechanics of staging figured out.
What's stumping me is how to monitor the staging.
For the backups, we currently have an in-house developed script which parses
through the savegroup completion messages for errors. It also draws on log
files for additional statistics gathering.
So, I'm looking for the data I can use to develop some sort of monitoring
process for the staging piece. From what I can see, using a staging policy
only results in "deletion" messages in
/nsr/logs/messages:
NetWorker media: (info) Deleted 16 KB from save set 3251150270 on volume
Disk.001
NetWorker media: (info) Deleted 350 KB from save set 3335036349 on volume
Disk.001
Staging the data by manually using nsrstage doesn't produce much more
information. So, how are you monitoring your staging operations?
Thanks.
Teresa
