[snips-users] about NetIErr & NetOErr

[Daniel MacKay <daniel at bonmot ca>]

I have taken a look at a couple of the NetIErr and NetOErr calculations.

They are expressed as a PERCENT of the total packets over a very 
short sample interval.

Does anyone else think this is not the best way of reporting a 
devastatingly important but tiny number?  By the time you got to 
seeing more than 1% of packets over such a short period, performance 
on your device is smoking wreckage.

I would like to propose that these be reported as counters, if at all 
possible, deltas since the last time hostmon ran (that is, two or 
three minutes.) If you have seen any Ethernet errors at ALL in the 
last 2 or 3 minutes, you have a problem.  Then maybe look at 
delta-time and report the number as something like 100x errors per 
minute (if it was reported as errors per minute it could easily be < 
1.)

Is it realistic to remember the values from the last iteration? 
Obviously you would have to not report the first run through after 
hostmon-osclient started up.
