Measurement marks are checkpoints in the process to measure time or business variables.
When the Engine routes the instance through a transition with a Measurement Mark, it performs all the checkpoints associated with the transition including the list of business variables which values the user wants to persist.
The information generated can be retrieved in the Audit Trail in the WorkSpace or used for the Process Data Mart.
Snapshot Start: indicates the start of a measurement. Time begins to run. As well, business variables are persisted.
Snapshot Stop: indicates the end of the measurement. Elapsed time is marked. As well, business variables are persisted. All Stop Measurement marks are referred to a Start one.
Snapshot Start & Stop: persists business variables values.
The following table outlines some of the considerations when using the Measurement Mark Activity within ALBPM Studio.
| WorkSpace | Measurement activities do not appear in WorkSpace. The information that generates can be retrieved in the Audit Trail. |
| Roles | Measurement activities can appear either in automatic roles or in the user defined role types. However, if the Measurement activity is in a user-defined role, it will not appear in WorkSpace. |
| Variables | |
| Pre Conditions | |
| Post Conditions | |
| Transitions | Measurement marks are associated to one transition. When the Engine routes the instance through that transition it performs all the checkpoints associated with the transition. |
| Tasks | |
| Business Process Methods | |
| Audit Trail | Measurement marks are registered in the Audit Trail. They show the values of the defined business variables. The Stop marks show also the elapsed time since the Start mark. |
