SYSACT Display the System Load

SYSACT [CPU | IO | SVC | PG] [, INT=n] [, TYP=typ] [, VAR=Y]

The SYSACT command is available as from BS2000 V10.0, and displays the current system load.

With a mouseclick you get a describtion of the screen item.

For a description of the individual load elements, see page .

CPU | IO | SVC | PG

The tasks which have used the most resources over the measurement period will be displayed in the last quarter of the screen. The layout will be identical to that appearing if a Task list is selected, together with the DELTA User Option (see page ). Specifying one of the optional parameters CPU, IO, SVC, or PG will determine the sort order of the tasks displayed: D-CPU, D-IO, D-SVC, D-PG (Delta CPU, IO, SVC, Paging).

INT=n Length of measurement period. Standard: INT=10.

TYP=typ The second-last section of the SYSACT mask ("NAME MN TYPE ...") is reserved for devices of a specific type. A simple or complex search condition can be specified for typ. For further information, see page . Example: TYP=D or TYP=D3490. Only disk IO's will be monitored if TYP=D is specified.

Standard: All device types will be monitored during the SYSACT analysis.

VAR=Y Specifying this parameter will cause various CFS variables to be created, and assigned respective values from the current SYSACT screen. The evaluation of measurement data in procedures is thus made much easier.

All the variables begin with the prefix SYSACT- (e.g. SYSACT-TSN-HEADER, SYSACT-TSN1). The CFS variables created, and their assocaited values can be used, for example, in a test procedure as follows:

TASNO

SYSACT VAR=Y

*SV

*STOP

Commands:

ATL [INT=m] This command will activate the automatic output mode. Specifying the optional INT=m parameter determines the time in seconds of the measurement intervals. Standard: INT=30.

HC file | NHC Activate/deactivate the Hardcopy mode. All screens displayed between the commands HC and NHC will be saved to the Hardcopy file.

F3 The current file displayed will be saved to the Hardcopy file when the F3 key is pressed.

/cmd Execute the BS2000 command cmd .

n/OCn/CCn/DCn/CD

CFS commands for controlling Connections. For further information, see page .

HELGA Call HELGA as a subprogram. Return by entering the HELGA command END.

TASK tsn A Display function for the task with the specified TSN will be executed. For information on the format of the Display screen, see page . Pressing the K1 key in the Display screen will execute a new SYSACT command.
