I get the following logs while running Metricbeat 6.2.1 on Docker Swarm. I am hosted on Docker for AWS which uses Moby Linux and that is based on Alpine if that helps. Is this a supported scenario? ```auto 2018-02-20T12:12:03.188Z ERROR instance/metrics.go:69 Error while getting memory usage: error retrieving process stats 2018-02-20T12:12:03.188Z ERROR

Hello @muhammadrehansaeed, This should work on all Linux, The log is interested I see a few errors: 1. The retrieve `process stats` 2. The missing `count` 3. Can't merge a non object mapping [docker.container.labels.com.docker.swarm.task] with an object mapping [docker.container.labels.com.docker.swarm.task I have a few questions: Do you have x-pack monitoring enabled? I think 1, 2, 3 errors might come from the monitoring feature. ---

Also by looking at line 7 of your log, I think you are also experiencing an issue with docker tags see this issue for a workaround. > ---

Thanks, the workaround fixes that issue. ---

I'm not using X-Pack monitoring because when your monitoring needs monitoring... ---

There is a problem getting information about the current process, I've created the following issue [https://github.com/elastic/beats/issues/6426](https://github.com/elastic/beats/issues/6426) to followup. Also, the current log statement hide the original error, making this problem a bit harder to debug than it should be. ---

Is there a workaround for this second error you have raised an issue for? What is the impact? What module does this affect, system or docker? ---

I believe it should only affect monitoring, so by turning it off it should be fine. ---
