Logging to datadog

Installation
1

I’m currently looking how to configure home-assistant to log in a format that would be easy to send to datadog.
Documentation seems to point out that configuring HA to write log in a json format would help.

Is there any way to configure HA in such way?

Did you get anywhere with this? My logs in Datadog are a mess at the moment, and I’m not sure if this is best fixed at the application-level by logging JSON, or in Datadog itself with pipelines.

No progress so far!

I eventually built something to support this. I tried to propose ✨ Allow to log in json format by kamaradclimber · Pull Request #110487 · home-assistant/core · GitHub but it got rejected.

However, I’ve been using a simpler version of the patch for several months with great success:

For non-log integration, I’ve also built GitHub - kamaradclimber/datadog-integration-ha: A better datadog integration for Home Assistant to get metrics and events sent to datadog.
