Overview

SM2 provides the user with information on the status and performance of the system, making it possible to improve the performance of both the system and its applications. The mode and scope of monitored data acquisition in SM2 can be controlled using commands and statements.

SM2 consists of a privileged subsystem and a nonprivileged user program. The SM2 subsystem generates a number of system tasks which are responsible for collecting data and writing it to the SM2 output files.

The following figure shows the exchange of information between the various SM2 tasks.
