The authentication logs can be mined for stats on unique users logging in
from the clients that you don't control. That gives a metric on active
users. The format of the logs isn't pretty though.
We keep various metrics gathered by our daily backup scripts, somewhat
easier than polling. The most useful over the years have been:
- total size of incremental dumps sent to our NetBackup system (all
volumes except our really big ones)
- used space in /vicep* (from df)
- total space in /vicep* (from df)
- number of user home volumes
- number of research data volumes
- total of all volume quotas
After a few years of keeping these stats, you can make pretty plots
showing growth of the cell, which seem to be popular with management.
Our large data volumes are usually replicated, and I'd love to have a way
to tell how much they change each day, as a measure of activity, but all
I've managed to do is measure the time needed to 'vos release'
