The TN3270 Server Sessions workspace provides the ability to monitor sessions from a remote TN3270 client to a z/OS TN3270 server. This workspace identifies the sessions that have high response times.
Some of the attributes in the tables and graphs in this set of workspaces display data only if the TN3270 Server you are monitoring is running on a z/OS version 1.8 or higher system. If you are monitoring a TN3270 server running on a pre-z/OS version 1.8 system, the average response times for all sessions are set to 0 and therefore all sessions are filtered out by the display filter.
This workspace is displayed by right-clicking TN3270 Navigator item and selecting TN3270 Server Sessions from the workspace list. If you are monitoring TN3270 servers running on z/OS version 1.8 or higher systems and you want to make the TN3270 Server Sessions workspace the default workspace, refer to the migration chapter of IBM Tivoli OMEGAMON XE for Mainframe Networks: Configuration Guide.
This workspace displays the following views:

The TN3270 Server Session Summary Tables displays performance data for TN3270 server sessions with an Average Total Response Time greater than 1 second. The displayed sessions have a collection time within the TN3270 display interval (by default, last 2 hours). This data includes active sessions (sliding window and bucket count metrics are collected for these sessions each collection interval) and sessions opened or closed since the last collection. There is no default sort order.
Right-clicking the row in this table provides links to the following workspaces:
