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. -Sam _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
