I'm looking for a way to setup auto-discovery based on docker hints for MySQL, as described here: [https://www.elastic.co/guide/en/beats/metricbeat/current/configuration-autodiscover-hints.html](https://www.elastic.co/guide/en/beats/metricbeat/current/configuration-autodiscover-hints.html) How can I set the MySQL user and password supported by the module ([https://www.elastic.co/guide/en/beats/metricbeat/current/metricbeat-module-mysql.html](https://www.elastic.co/guide/en/beats/metricbeat/current/metricbeat-module-mysql.html)), but using the labels instead? There are only a few labels supported as hints and I would like delegate to the configuration to the target, and not the metricbeat instance. Thanks! ---

Hi @stingus, how about using [`co.elastic.metrics/raw`](https://www.elastic.co/guide/en/beats/metricbeat/current/configuration-autodiscover-hints.html#_co_elastic_metricsraw)? ---

Seems that not all json keys/values are parsed from co.elastic.metrics/raw. Tried to set the `user` key but its value isn't passed to the module. So my guess is that only accepted keys are the ones listed on the [hints based autodiscovery page](https://www.elastic.co/guide/en/beats/metricbeat/current/configuration-autodiscover-hints.html). ---

Hey, tried to reproduce it (with mongodb module) and I can see the `username` config to be set. Could you check that your hints are correct. The key is [`username`](https://github.com/elastic/beats/blob/ba8a45e6726525ed4d4fbbaaef7daaaee89b9b66/metricbeat/module/mysql/_meta/config.reference.yml#L15) and not `user` just in case. In any case we should consider adding username/password to known hints list. I will open a Github issue for this. Thanks for bringing this up! Regards! ---
