Resolution

Below are the steps to create a trace_read:

Create a <SPECROOT>/SS/trace_read file.

Add Trace Criteria: Populate the file with the specific model handle and attribute ID you wish to monitor using the following format:

 

I <Model_Handle> <Attribute_ID> <Buffer_Size> W (to trace writes)

I <Model_Handle> <Attribute_ID> <Buffer_Size> R (to trace reads)

 

The trace output will be written to the $SPECROOT/SS/VNM.OUT file. Look for entries noting "Tracing Reads/Writes" to confirm it is active Traced Reads/Writes Messages.
