2 The SM2 monitoring program
2.1 Overview
SM2 is a shareable program that runs under BS2000. It provides the user with information
on the status and performance of the system, making it possible to improve the perfor-
mance 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 generates a number of system tasks which are responsible for collecting data and
writing it to the SM2 output files.
SM2 consists of privileged and nonprivileged components. Figure 1 shows the exchange of
information between the various SM2 tasks.
