I noticed that in your RFC.  How are you planning on presenting the data 
to other agents (e.g. Nagios, Openview, MRTG, etc.)?  One comment that I 
should have made on your RFC is that I wonder if it is necessary to 
include the data analysis/reduction part.  Just having a central 
location that collects the values and presents it via SNMP is extremely 
useful since there are a plethora of monitoring apps (free and 
commercial) that  do what you are proposing.  That way, a network 
manager can leverage existing tools currently used for monitoring 
Ethernet Nodes, Hosts, etc.  You can still include a last change 
attribute with each counter so that simple utilities (like the one that 
I am writing) can get an idea of how quickly errors are occurring.
