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 twice with
	 the same arguments, the produced data is doubled for the output service
	 ID.

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.

OPTIONS
     --step
	 Default: 300. Sets the data interval for derived service ID. It is rec-
	 ommended to leave this option at default value.

     --verbose
	 Prints extra informatgion.

     --debug
	 Prints debugging information.

     --help
