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.<br>
<br>
Thanks,<br>

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