Portal Monitoring: Avg Memory Consumed Per User?

[Former Member]

For some (very) basic capacity planning, I am looking for a good metric on memory consumed per user in a NetWeaver 7.0 Portal SP18.

So for example, if we have 30 active sessions using 5MB memory a piece, I could then roughly assume that an additional 20 active sessions would consume an additional 20 x 5MB = 100MB and plan accordingly.

I can kind of put this together using NWAu2019s Monitoring Java System Reports, but garbage collection and the base memory consumed by the Java engine really clouds the issue. Any suggestions on how to measure average memory consumed by a user session? Seems like a really basic metric to want to see!

Hi,

Since memory allocation/consumption is object based on typical Java applicaiton, you got to take Heap Dump and examine the heap to determine the utilization.

Portal doesnt work like it does on the internal ITS where you can go in and see memory per user

or that a user typically has an average memory footprint.

Otherwise, there is no mechanism using tools like Wily, SMD, NWA or VA to determine per user.
