After receiving some questions from customers we noticed that a few pieces are not documented. Particularly Tags 

• Asset

• Interface

• Node

• Service

• Resources

• Custom

This tags are defined in the timeseries plugin properties. Like cortex.properties

Knowing what exists as an allowed tag will help the users better decide what data they would like to track.

Current information how define tags can be found here 

Documentation (BR):

In the “OpenNMS Time Series DB” section (hosted-tss.adoc, ), update the “Deployment” topic:

1. In the “Configure plugin settings” step, add a properties block that shows how to define the tags listed above, similar to how the cortex properties are described in step 4 of the Cortex TS plugin Deployment topic ( ).
