I assume that these values are exposed to eg the status server so we can see them with current monitoring probes, eg monit ?
Not yet. I suppose that could be done.

Yes, that too.
The issue there is WHEN do you send traps?
- when the queue of delayed packets gets more than half full?
- when the PPS IN-OUT> ... ?
- how to rate limit the traps so that you don't get spammed by them?
What criteria should be used?
Maybe best to leave this to external tools; just expose the absolute COUNTER, and the various rate GAUGE values, and let the tools send the alerts, IMO. For what it's worth, a suitably compiled net-snmp can watch its own internal OIDs and execute user-configurable threshold traps.
