4.5 BS2000 commands for activating user task monitoring
Any user can have SM2 monitor tasks under his/her own ID, provided the SM2 primary
administrator has given permission for user task monitoring (by issuing the SM2 statement
MODIFY-USER-ADMISSION TASK=*ALLOW. The total number of tasks which can be
monitored simultaneously is limited to 16).
Only users who have been assigned the system privilege SW-MONITOR-ADMINIS-
TRATION can start or terminate monitoring of any tasks.

Function
The BS2000 command /START-TASK-MEASUREMENT is used to specify the tasks to be
included in the monitoring process. The SM2 software monitor then records task-specific
monitored data and enters this data in a user-specific file.

In addition to task-specific monitoring data, program counter statistics and SVC statistics
on program runs can also be requested.
on program runs can also be requested.
In the case of program counter statistics for counting commands, the program is interrupted
at defined intervals (using a timer) and the address of the next command to be executed
and contained in the program counter is transferred to the user-specific SM2 output file
(registering the number of times the counter sampled the program).

In the case of SVC statistics, all SVC program macros called during task monitoring are
recorded, and SVC numbers and macro addresses are also stored in the SM2 output file.

If the BS2000 command /STOP-TASK-MEASUREMENT is issued or the task is terminated,
user task monitoring ends and the user-specific SM2 output file is closed. In addition,
withdrawal of the primary SM2 administrator’s permission to monitor tasks (MODIFY-
USER-ADMISSION TASK=*INHIBIT) as well as deactivation of SM2 (STOP-SUBSYSTEM
SUBSYSTEM-NAME=SM2) will terminate any currently executing task measurement
operations.
