Regarding your solution here, I've tried the same but got no luck.
(https://discuss.elastic.co/t/restrict-remove-unnecessary-fields-in-metricbeat/144193)
I've enabled only System, CPU, Memory, Process Status/Modules. I tried to use the processors (drop_fields, include_fields - MetricBeat is running as service in linux machine. I've restarted the service but still in the kibana output, I'm seeing the fields again)
Can you please help me in this.
I can post the logs if you can reopen the question??
Note: This question is meant for the link "How to remove Metricbeat default fields 1".
Thanks,
Vijay
