Hi !
you could change the cisco-mib entry of bufferFail
from INTEGER to COUNTER, recompile the mib and than
create the mib-expression
BUT
if you multiply by 3600 every delta larger than 1/3.6 per second
will set off the threshold of 1000/hour on the premise that the
router will generate those bufferFails in the hour which lies ahead,
which is probable not the reason you want to do this in the first
place

Subject: [NV-L] Integer Thresholds
Does anyone have any ideas how I can solve this problem:
I want to set an SNMP data collection threshold of 1000/hour for Cisco
routers bufferFails MIB variable. The variable is defined as an INTEGER
(not a COUNTER).
Here is what I tried so far, and why it doesn't work:
1. Use mib.coerce to force the variable to be a Counter. This doesn't
work because I want my threshold to be 1000/hour, snmpCollect
shows counters as units/second (can't find a way to change that!)
and Thresholds cannot be set for less than 1 (1000/hour is 0.278
units/second).
2. Make an expression with the variable that is "coerced"into being a
counter by multiplying it by 3600. This doesn't work because for
MIB Expressions - NetView seems to ignore the mib.coerce file. It
just ends up multiplying the Integer value by 3600, not the delta
value.
What I resorted to was collect the data as an Integer (default), use
snmpColDump to feed the data into an awk script that will calculate the
rate/hour of the integer change. However, because of buffered I/O, I
can't use the -f flag of snmpColDump to continually feed this data into
an awk script (it buffers up a bunch of lines before it sends it to awk
to process - meaning it only sends data every couple hours!).
Isn't there another way?
