Retrieve statistics for all tasks into $list

Note: Many $functions are deprecated in favor of Object Oriented methods. There is no OO equivalent for the $TkStatL function.

This function allows retrieval of statistics for all tasks into a $list.

The $TkStatL function accepts two argument and returns a numeric error code.

Syntax

%result = $TkStatL(list_identifier, stat_list, criterion)

Syntax terms

%result Either a positive number, which is the milliseconds since the online was brought up, or a negative error code.
list_identifier The identifier of the $list that is to receive the results. The current contents of the $list are deleted and replaced with the requested statistics. The format of each $list item is:
Byte 1-10 Blanks
Byte 11-12 Binary task number
Byte 13- Returned statistics
stat_list A string of blank-delimited words indicating the statistics to be returned. The length of each returned statistic is always a multiple of four bytes. This facilitates the use of $StatLD with the returned $list.

For more information about available statistics, see Task statistics displayed in SirMon.

Return codes

-3 - No room to create $list items (if LISTFC $SirParm parameter not set) -5 - Required parameter not specified -6 - Invalid $list identifier -13 - STAT not linked in

Example

The following program displays some statistics for all tasks:

B %DATA IS STRING LEN 255 %LIST = $ListNew %DATA = $TkStatL(%LIST, 'CPU STDEQ LKWAIT') IF %DATA < 0 THEN PRINT '$TKSTATL ERROR... RC = ' WITH %DATA STOP END IF FOR %I FROM 1 TO $ListCnt(%LIST) %DATA = $ListInf(%LIST, %I) PRINT 'TASKNUM = ' WITH $UNBIN( $SUBSTR(%DATA, 11, 2) ) PRINT 'CPU = ' WITH $UNBIN( $SUBSTR(%DATA, 13, 4) ) PRINT 'STDEQ = ' WITH $UNBIN( $SUBSTR(%DATA, 17, 4) ) PRINT 'LKWAIT = ' WITH $UNBIN( $SUBSTR(%DATA, 21, 4) ) PRINT END FOR END
