I’m new in TSDB and I configured a GuestDB and Telegraf as gateway from an Opcua input. All the components are working as expected and i note that each single row (for all input tags) has the correspondant value and timestamp, an the colum name are null.

I’m asking how is it possible to have a more dense form where timestamp in common for all the values in the differents columns ?

From:

OpcItemID.X, timestamp, valueX, null, null
OpcItemID.Y, timestamp, null, Valley, null
OpcItemID.Z, timestamp, null, null, Valdez

to

Empty, timestamp, valueX, Valley, valueZ

Where i can find some i input? fir that, seems that aggregators.merge is not working …
