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 :-) -- Sincerely, Nathan Gibbs Systems Administrator Christ Media http://www.cmpublishers.com |
