I have recently started exploring the elastic products and was able to run ElasticSearch, Kibana, and MetricBeat on my workstation and I was able to view system metrics on Kibana dashboards perfectly.
I wanted to ship metrics of a raspberry pi powered device to the above setup. For that, I was able to build Metricbeat on Raspberry and used the same workstation for elastic-search and kibana.
Metricbeat ships data to elasticsearch cluster but I guess it's incomplete. On Kibana Dashboard, CPU usage, Memory Usage, Traffic etc are always 0 but I can see the number of processes. I have attached screenshot of the Dashboard.
fields.yml and system.yml are not modified.
I am stuck in it for 2 days and unable to figure out the exact reason for this behavior.
Any help would be greatly appreciated.
