Hi, I can't found out the swap usage for the Docker module in the memory metricset, it seems that it is only supported for the System module, am I right? By the way, the memory metrics refer to the RAM of the container, right? ---

Yes, seems like we don't have swamp in the docker memory metrics. I don't know if we actually can get it from the docker api. Do you want to open an enhancement request for it here? [https://github.com/elastic/beats](https://github.com/elastic/beats) Yes, docker memory metricsets is that of the container. ---

All right thanks. Yes, that would be a good enhancement. ---
