The SIS records the following statistics for conducted dialogs.

Note Conducted dialogs are network-initiated dialogs for which the SIS receives a trigger event, and imposes some orchestration behaviour onto.
Statistics

Activities

Live activities — liveActivities

Records the total number of…​

…​live conducted dialogs for which the SIS instance has executed one or more services. (Trigger events that do not execute services do not affect this statistic, since the dialog closes immediately after sending a response to the trigger.)

Increments…​

…​whenever the SIS instance receives a trigger event from the network, and determines that it needs to deliver the event to one or more services.

Decrements…​

…​when a conducted dialog terminates.

Dialogs Accepted

Total dialogs accepted — acceptedDialogs

Records the total number of…​

Total dialogs accepted for non-zero-length compositions — acceptedDialogsNonZeroLengthComposition

Records the total number of…​

Initial response time — responseTime

Samples…​

…​SIS initial request response time.

When…​

From the time the SIS first considers the initial request for delivery to services…​ to the time all required services have executed and the SIS has sent its response to the network.

Calculates…​

Initial response time of trigger events for which the SIS has invoked at least one service.

If the SIS does not select any compositions for the initial request, it either:

  • selects a composition which determines no services to execute

  • performs an internal redirect only

In either case no initial response time is sampled, as processing time would be negligible.
