Lotus Domino and SNMP memory graphing

[ahnberg]

Greetings,
I just wanted to give a heads up to anyone interested in using SNMP to graph the memory usage of a Lotus Domino server with more than 2Gb memory.

During our own setup (more than 4Gb memory) I stumbled over weird values and noticed that the MIB claims that there is only support for up to 2Gb. I opened a case with IBM to verify this, which they did.

I'm just about to open a feature request with them to fix this down the road, but for current situations everyone with more than 2Gb memory can't accurately use the Domino SNMP implementation to graph memory usage.

Please correct me if I am wrong or if you have another solution to the problem (scripting something on the OS level to properly spill out the memory usage would be an alternative, I guess).

Check the "Value Ranges" dropdown at the following URL for the MIB information too that supports the above problem:

Hope this is of some use for someone.
