Monitoring the State of a Session

Often you want to know information about a particular session, such as its state, its

creation time, the list of activities assigned to the session, or information about any

such assigned activities that are in ACTIVE state.

➤To obtain state information about a session

1. Open the iIS Console and select the engine to monitor.

2. Choose Monitor > Sessions, or choose Sessions from the popup menu.

This opens the list of current sessions.

For each session in the list, the window displays an ID, the user who opened

the session, the state of the session, and the number of items on the session’s

activity list.
