Exclude some fields in the incoming data

The issue is to exclude some fields in the incoming data. I did refer this

Can anyone explain how to configure influxdb to exclude the selected fields?

What do you mean with Incoming data? are you using Telegraf or something else?
Elaborate your question because as it is it’s not clear waht you are trying to achieve

I don’t think I am using Telegraf. I have installed influxdb and streaming data into it directly.I want to know how to configure influxDB to exclude some metrics when we write data to the measurement.

Afaik you don’t do that on the database side, you must do that in the gatherer, whichever it is.
