What is the data_source_type_id in the cacti XML

Sometimes it is easy to search on google for cacti templates and use them in zenoss.

A good example is this one: http://forums.cacti.net/about10589.html

As you can see someone create XML templates for a Cisco PIX/ASA
I would like to add the OID's to a zenoss datasource.

When I open the XML there is a part which describes the data source ID.
Here you can find the list to the translated value.

data_source_type_id = 1 = "GAUGE"
data_source_type_id = 2 = "COUNTER"
data_source_type_id = 3 = "DERIVE"
data_source_type_id = 4 = "ABSOLUTE"
