Sam,
Thanks for your help. I am going to contact the vendor, as I believe
something is quite wrong. Not only is that counter not functioning properly
for a counter, but unless I'm missing something, I don't believe a counter
is the best choice of types to monitor an object that fluctuates so much by
design.
Thanks,
Jeff

Jeff,
I can't tell you what's going on with that counter. I don't imagine
the appliance has 4 million objects currently open, so that number
looks like nonsense. Google to look for an issue specific to the
appliance vendor, and if you don't see anything, contact the vendor
directly. It's not uncommon for there to be bugs in an SNMP data
model.
If you want to graph the delta (in objects opened/closed per second),
you should use the DERIVE data source type. That will subtract the
new counter value from the old counter value and divide by the number
of seconds between the data points. If you want to display the actual
counter value, use the ABSOLUTE data source type. I can't tell you if
either of these is an appropriate interpretation of the data; you'll
have to work with the vendor to work that out.
