Yes - I see what you are after now.
The real problem with this is that there aren't really any hard-and-fast rules about a lot of the counters. In we take a couple of examples :-
1. On any interface, the CRC error counter should always be zero, but then if you get a few CRC errors, do you spend time investigating something which is a relatively minor problem? Also, what figure do you take as being the threshold and when does it become a more serious problem?
2. The collision counter on a half-duplex ethernet interface is likely to be non-zero, especially if the utilisation is high, because collisions are part of the normal operation of ethernet. But again, what to you say is an acceptable value, and where do you set your thresholds?
This is a very difficult area to pin down I reckon, because the whole question of thresholds is fairly subjective. I've just had a quick scan on Google, but most of the replies are fairly high-level and don't get down to the sort of level that you are after. They generally talk about this like how to set up Network Management, SLAs and so on.
So, sorry not to be much help here and good luck in your quest.
Pete
