Teresa,
Writing my nsr reporter (and the nsr_device_monitor part), I also
detected such a problem.
The only way to X-check and bypass the problem is
in your nsradmin query, to add volume label field :
old
-> show nsr operation;volume operation;minor mode;name;statistics
new
-> show nsr operation;volume operation;minor mode;name;statistics;volume
label
If volume label is empty, no volume are loaded. If volume label is
empty,
then stats are wrong and may be ignored.
It's only workaround I found and I strongly believe it to be a bug,
occuring when sessions are like aborted, that stats to not be
properly cleaned in memory.
You can also do a crosscheck using following fields from type:nsr
ressource :
session statistics:
session message:
session client name:
session rate:
session rate label:
session device name:
They are indexed ( session statistics[0] with session message[0] ....)
>From devices, gather volume labels. Compare with session statistics data
and you can deduce inactive volumes (and wrong data) to ignore.

Subject: [Networker] Count of active sessions
Hi,
I'm trying to gather information about the number of sessions active on
each drive. I'm using the following as an input file for nsradmin:
show nsr operation;volume operation;minor mode;name;statistics
print name : /dev/rmt/3cbn
Currently, that drive is idle and empty (cut/paste from nsrwatch):
/dev/rmt/3cbn(J) 8mm AIT-3 (none) unmounted (already)
But, the nsradmin query returns this:
name: /dev/rmt/3cbn;
volume operation: ;
NSR operation: ;
minor mode: ;
statistics: elapsed = 1901240, errors = 0, last rate =
0,
max clients = 11, file marks = 95,
rewinds = 473, files skipped = 7479,
records skipped = 319536, current file =
89,
current record = 9217, seek files = 0,
seek records = 9214, estimated kb = 0,
amount kb = 80921728, file amount kb =
1179776,
sessions = 1;
which has the number of sessions listed as "1". All my other drives
list "0" when the drive is idle and empty.
Does anyone have any ideas why nsradmin thinks there is a session for
this drive?
Thanks.
Teresa
