System resource utilization

Notes on SM2 operation

User task statistics

The system load caused by the activation of user task statistics by the BS2000 user with the aid of the /START-TASK-MEASUREMENT command is mainly the result of program counter statistics and SVC statistics.

Program counter statistics

The system load caused by program counter statistics depends on the following factors:

the sampling cycle selected

the number of tasks monitored

6.1.3Main memory utilization

SM2 requires storage space for its code and for tables and I/O buffers.

The subsystems for the monitoring programs RESPONSETIME and UTM are loaded subsequently if required.

Some system modules are resident, others are paging modules. The size of the tables depends on the number of objects to be monitored.
