Hi Joe,this is an Linux Server and the model is represented as Net-SNMP Linux.When I'm looking on the attributes, I see the negative value, too.
Is that meaning, that the SNMP Agent on the Linux Server is causing the negative value?
After upgrading the Linux UC Davis Net-SNMP agent to the latest version no longer seeing valid Memory metric data.
Do check the version enter the following command:
rpm -q net-snmp
So any device that upgrades the net-snmp to the new version you will need to look at the
"Memory Without Buffer Cache" data in CA Performance Center.
It is not guaranteed to be negative values for the old but if it does then you need to look at the new
"Memory Without Buffer Cache" values.
I would with support and was able to get one created a few months back. I ended up creating a new Metric Family:
Memory Without Buffer Cache
Please let me know if you need a copy of it.
