Hi, Giovanni. Thank you for your interest in this issue.
I think I’m not doing any filter, only pointed to the database I want to storage the metrics. I’m sorry, I’m beginner with Telegraf and Influx, do you think this documentation could be helpful?
Configuring Telegraf | Telegraf 1.21 Documentation (influxdata.com)
Also, I think this issue is related but I don’t understand how to use namepass, if that’s the filter.
