About Installing SAU Extension

To install Session Monitor with the SAU and SAtU Extension enabled, follow the instructions in Session Monitor Installation Guide. On all Session Monitor machines, at the configuration step in the Session Monitor Platform Setup Application, select Simultaneously Active Users extension.

The following figure shows the configuration step in the Session Monitor installation.

If your setup has an Aggregation Engine (AE) machine, you need to install the Mediation Engine Connector (MEC) on it and configure MEC to connect to all the installed Mediation Engines (MEs).This is because the SAU extension relies on the same communication path used by MEC to communicate with the MEs.

If the Simultaneously Attached Users (SAtU) KPI is required, which is based on Diameter traffic, the Control Plane Monitor (CPM) must be installed on all Mediation Engines. This is because the CPM is measuring the number of attached users. If only the SIP based Simultaneously Active Users KPI is required, CPM is not needed and should not be installed.
