$UsStat
Retrieve user's statistics into string
Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $UsStat function is the UserStatistics class.
This function allows retrieval of a specific user's statistics into a string.
The $UsStat function accepts two argument and returns a string made up of an error code and returned statistics.
The first argument is 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 User's Guide.
The second argument is the user number of the user for which data is to be returned.
Syntax
%STRING = $UsStat(stat_list, user_num)
%STRING is made up of binary data, the first 4 bytes of which is an error code. If the error code is negative %STRING will only be 4 bytes long.
The data returned by $UsStat is binary with the first 4 bytes containing an error code. If the error code is negative, only 4 bytes are returned. If the error code is positive, it contains a number of milliseconds that the online has been up. This provides a convenient number for calculating rates for the statistics. When a positive error code is returned the next 10 bytes contain the userid followed by 2 bytes containing the binary user number. This means that the actual data starts at offset 16 (byte number 17) in the result string.
-5 - Required parameter not specified -12 - Invalid parameter (argument 2 > NUSERS) -13 - STAT not linked in -14 - Result string would be longer than 255 bytes -15 - User not logged on any more
$UsStat return codes
The following program displays some totals for user 0.
B %DATA IS STRING LEN 255 %DATA = $UsStat('CPU SVIO DKIO', 0) IF $LEN(%DATA) = 4 THEN PRINT '$USSTAT ERROR... RC = ' WITH - $UNBIN(%DATA) STOP END IF PRINT 'USERID = ' WITH $SUBSTR(%DATA, 5, 10) PRINT 'CPU = ' WITH $UNBIN( $SUBSTR(%DATA, 17, 4) ) PRINT 'SVIO = ' WITH $UNBIN( $SUBSTR(%DATA, 21, 4) ) PRINT 'DKIO = ' WITH $UNBIN( $SUBSTR(%DATA, 25, 4) ) END
