NAME

       srvderive - Derive a new service ID from sum or maximum of other service values

SYNOPSIS

       torrus srvderive TIMESPAN OUTPUT FUNCTION SOURCES...

DESCRIPTION

       When the Torrus Reporting engine is set up, this command is used to combine several services data into a new service ID. The output data is
       either the maximum or the sum of input services.

       See Torrus Reporting Setup Guide for more information.

TIMESPAN

       Either --month or --end option must be defined

       --start=YYYY-MM-DD
	   Sets the start date of the calculation.

       --end=YYYY-MM-DD
	   Sets the next day after the eond of the period.

       --month
	   Instead of setting the end data, it is convenient to use this option. It sets the end data in one calendar month after the start date.

OUTPUT

       --out=SERVICEID
	   Sets the output service ID. This should not be a service ID used in the Torrus datasource trees. Note: if srvderive command is run

FUNCTION

       --func="MAX"|"SUM"
	   Sets the function to be used when combining the input service data.	Currently only "MAX" and "SUM" are supportted.

SOURCES

       --in=SERVICEID ...
	   Input service IDs are specified either by --in option, or as command line arguments. At least 2 input service IDs should be specified.
