[Devmon] input discard rate

[Taylor L. <tl...@tr...>]

Is anyone out there using devmon to monitor a 6509?  If so, do you ever
get messages about a link having a very high input discard rate?

 

And if so, what does that mean?  I can see output discard counters on
the switch by running show int gi#/# counter errors, but I don't see any
counters for input-discards, only output-discards.

Also, if you look below, the Discards In reports as 0, yet the rate in
reports as 72796055, and a 4386%, so I think something is wrong with the
way devmon is calculating the discard load in.  

 

Ifc         name                            Discards in        Discard
rate in   Discard load in   Discards out      Discard rate out
Discard load out

Gi#/#    [*** some link ***]           0
72796055.85      4386.49%                      0
0.00                              0.00%

 

And the rate we are getting is unreal (see above).  We aren't hearing of
any problems on this link, yet devmon is reporting.  This happens about
once an hour and lasts about for one poll cycle, i.e. one minute.
