noob’s question: i’m trying to configure telegraf to fetch data from two different mqtt servers, outputting to seperate databases. i found this, which i guess should handle the outputs: Routing metrics by plugin opened 12:51PM - 16 Sep 16 …

check this out: telegraf/CONFIGURATION.md at master · influxdata/telegraf · GitHub last example. think i got the hang of it now with this. essentially you’re using the tags to mark/label/flag metrics and then either pass it to a given output or not by filtering/selecting. so my second mqtt-input …

Hi @markusk , I believe it would be a lot simpler to run 2 telegraf processes on your machine, each configured with an input and output. Do you have any constraints that require this to be a single telegraf instance?

well, no real constraints i guess - though running in a docker container on a rather weak NAS… but gotta question the modular concept of plugins, if i still need to multiply monolithic constructs … or is all this just “not there” yet? thanks.

Assigning inputs to outputs is certainly something that we’re happy to see implemented, but with 2.x so close; it’s going to need to be community contribution for now.

You can do this with a single Telegraf, there are very few reasons to run Telegraf more than once on a system. Your strategy is the right one, just have multiple mqtt_consumer tables, can you show your config and the parse error you are seeing?

thanks … quickly gave it another try before heading to bed … indeed telegraf started up with two mqtt-inputs defined - without adding a tag … a quick search revealed that i had it put in the wrong place, directly after the opening [[inputs.mqtt_consumer]] though it should go to the end … unfortuna…
