Retrieve subsystem's statistics into string

Note: Many $functions have been deprecated in favor of Object Oriented methods. There is currently no OO equivalent for the $SsStat function.

This function allows retrieval of a specific subsystem's statistics into a string.

Syntax

%string = $SsStat(stat_list, subsystem_name)

%string A string of data. If the string contains exactly four bytes, it is a binary error code.

Otherwise, the first four bytes contain the unsigned binary number of milliseconds that the Online has been up. This provides a convenient number for calculating rates for the statistics. The next ten bytes contain the blank-padded file name, then follow two bytes containing the binary file number. This means that the actual statistical data starts at offset 16 (byte number 17) in the result string.

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 4 bytes. This facilitates the use of $StatD with the returned string.

For more information about available statistics, see the SirMon M204wiki pages.

subsystem_name The name of the subsystem for which data is to be returned.

Return codes

-5 Required parameter not specified -12 Invalid parameter (argument 2 > NUSERS, or invalid name in stat_list) -13 STAT not linked in -14 Result string would be longer than 255 bytes -15 Subsystem not active

Example

The following program displays some totals for subsystem SIRMON.

B %DATA IS STRING LEN 255 %DATA = $SsStat('NUSER RESEVAL RESSWCH', 'SIRMON') IF $LEN(%DATA) = 4 THEN PRINT '$SSSTAT ERROR... RC = ' WITH - $UNBIN(%DATA) STOP END IF PRINT 'SUBSYSNAME = ' WITH $SUBSTR(%DATA, 5, 10) PRINT 'NUSER = ' WITH - $UNBIN( $SUBSTR(%DATA, 17, 4) ) PRINT 'RESEVAL = ' WITH - $UNBIN( $SUBSTR(%DATA, 21, 4) ) PRINT 'RESSWCH = ' WITH - $UNBIN( $SUBSTR(%DATA, 25, 4) ) END
