Retrieve system statistics into string
Note: Many $functions have been deprecated in favor of Object Oriented methods. There is no OO equivalent for the $SyStat function.
This function allows retrieval of system statistics into a string.
%string = $SyStat(stat_list, [stat8])
|%string||If the length of the returned value is exactly four, %string is a binary number indicating an error code. |
Otherwise, the first four (or eight if stat8 set to
The next ten bytes contain the blank-padded word
|stat_list||A string of blank-delimited words indicating the statistics to be returned. Each returned statistic is a 4 (or eight if stat8 set to |
|stat8||A integer that, if set, can only have a value of |
-5 Required parameter not specified -12 Invalid name in stat_list -13 STAT not linked in -14 Result string would be longer than 255 bytes
The following program displays some totals for system statistics.
B %DATA IS STRING LEN 255 %DATA = $SyStat('CPU DKIO SVIO') IF $LEN(%DATA) = 4 THEN PRINT '$SYSTAT ERROR... RC = ' WITH $UNBIN(%DATA) STOP END IF PRINT 'CPU = ' WITH $UNBIN( $SUBSTR(%DATA, 17, 4) ) PRINT 'DKIO = ' WITH $UNBIN( $SUBSTR(%DATA, 21, 4) ) PRINT 'SVIO = ' WITH $UNBIN( $SUBSTR(%DATA, 25, 4) ) END
