Description

Use Case

Hello and thank you for an excellent product!

I would like to have an output plugin for sending data to ClickHouse. With support for sending different metrics to different tables.

PS. I know about the existence of the SQL plugin and HTTP plugin. Using these plugins and some “crutches” you can send data to ClickHouse. But this is extremely inconvenient and has very limited settings.

Expected behavior

easy use native plugin

Actual behavior

“crutches”

Research direction
The issue requests a ClickHouse output plugin for Telegraf. To implement, one should study Telegraf's existing output plugins, such as the SQL or HTTP plugins, as references. The implementation would involve creating a new plugin package that conforms to Telegraf's output plugin interface, then registering it. Key files to examine include plugins/outputs/sql/ and plugins/outputs/http/. The contributor should also check maintainers' comments in the issue for any initial discussion or constraints.
