These Application Response Measurement (ARM) statistics can be obtained when a call is submitted (fire and forget) with a synchronous implementation.
Event monitoring for Service
Component Architecture (SCA) components includes the event points
that are shown in black
, while the
event points shown in blue are used only
to calculate and fire PMI/ARM statistics.
In Table 1 and Figure 1, the "current" ARM transaction (denoted as X1) is created when the calling service component was invoked for the first time. If the caller is not a service component, the current ARM transaction is used, or a new one is created. If it is not the starting transaction, it has a parent, as represented in the following table and diagram with the notation Xn.Xn+1. The notation is used to show the transaction lineage. Every SCA invocation starts a new transaction, which is parented by the current transaction of the caller. You can create new transactions and you can access the current transaction, but you cannot modify the SCA transaction lineage.
