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 recommended to
           leave this option at default value.

       --verbose
           Prints extra informatgion.

       --debug
           Prints debugging information.

       --help
