Could you narrow down which metricset is returning incorrect events? Could you please share the output of `./metricbeat -e -d "*"`? ---

Hi kvch, thanks for the reply. I have only two modules enabled, docker and system. When I disable system (by running `mv /etc/metricbeat/modules.d/docker.yml /etc/metricbeat/modules.d/docker.yml.disabled`), the error message no longer appears. So it should be a problem within system module. This is the output of `./metricbeat -e -d "*"`: ```auto 2018-07-23T22:53:20.940+0800 DEBUG [logstash] logstash/async.go:142 123 events out of 123 events sent to logstash host localhost:5044.

Great! And which metricset of `system` produces this error? ---
