The stats database is located at /opt/mwg/lock/statistic/statistics.db.
You could dump the keys via:
sqlite3 -line /opt/mwg/lock/statistic/statistics.db 'select key from stat;'
If you have defined your own statistic values, they will show up with a key name suffixed .4575
That's great—assuming it truly is exhaustive.
And, deeper descriptions would be nice, as verbose naming is often not nearly verbose enough.
I'm pretty sure that that's the only place that stats are stored, but if you want a definitive answer, you'll need to get it from McAfee.
It looks like 7.7 added ~2 dozen new key values, but many of them seem to be associated with iterations through a specific parameter. For example, these:
All evidence suggests to me that the statistic values are updated through more than one mechanism, but I am unclear as to which activities trigger the incrementing of which statistics.
