Hi
I installed metricbeat on my linux host, when I checked on inventory, the processes tab seemed to not be able to load, but when I checked on discover, metricbeat is still able to get the system.process logs properly. I also installed metricbeat on my windows host and the processes tab are working just fine there.
I used the linux tar installer to install the metricbeat
Here is the processes tab I got from my linux host (the metrics tab is working just fine too):
