Avaya ERS Memory Utilization from OID calculation

Avaya ERS Memory Utilization from OID calculation

I am attempting to create a custom monitor that will provide Memory Utilization for Avaya ERS 45xx/5xxx switches. Avaya allows access to an OID for Total Memory (.1.3.6.1.4.1.45.1.6.3.8.1.1.12) and one for Available Memory (.1.3.6.1.4.1.45.1.6.3.8.1.1.13). I have created monitors for these individual OIDs to be sure the data is available and correct results are returned.
 
I would like to create the monitor and associate it with the Memory Utilization snapshot dial.
 
I looked at the following KB article:
 
 
Based on this, I think I should use something like:
 
((.1.3.6.1.4.1.45.1.6.3.8.1.1.12 - .1.3.6.1.4.1.45.1.6.3.8.1.1.13) / .1.3.6.1.4.1.45.1.6.3.8.1.1.12) * 100
 
When I create the bulk monitor using the expression above, it fails to return any data. What am I missing?
 
Also, do you have any templates for Avaya ERS devices in the works?
