[Mon-devel] Network I/O Error question.

[Nathan G. <na...@cm...>]

Hi all,

Does anyone have an idea of what a sane number would be for I/O errors
including discards, on a network interface in, say a five minute period.

One of our systems recently had a NIC failure.
I spent over an hour swapping cables, messing with switch & firewall
settings, etc.
Finally, I happened to try looking at the NICs on the failing system via
SNMP.
What I saw was a system with 2 NIC's functioning perfectly, and one NIC
with an error count of over 400,000.
Obviously, a hardware failure & something that mon could cover.
:-)

I'd like to be sure that the default value for acceptable error counts
is something sensible before releasing the monitor for this.

Currently I have a default of 1000.

There is also the idea of a baseline acceptable error count that could
scale based on the interface type detected, as a faster interface could
experience more errors in a shorter amount of time.

Any thoughts, ideas, or recommendations for a base acceptable error count?

Thanks
:-)
