Let me explain the problem and context. This is a server for a database solution. The database was created with docker, and added a volume to the server. Then all docker installation path was moved to the volume added to the server (for security and backup mantain). Then for monitoring, i added a metricbeat agent to capture data, like disk and other stuff, but for this context occurs the problem.

Im searching for a specific mount (the is a volume mount), and when in terminal type df -aTh | grep "/dev" for show filesystem, its show this image:

Then in metricbeat.yaml i have this configuration for system module:

- module: system
  period: 30s
  metricsets: ["filesystem"]
  processors:
   - drop_event.when.regexp:
       system.filesystem.mount_point: '^/(sys|cgroup|proc|etc|host|hostfs)($|/)'

Notice in last line i omitted "dev" , because i want to obtain the mount volume "/dev/sda" high lighted in the screen shot. But when i discoverd in kibana, that device is not showed, and i dont now why, must be showed.

Thanks for reading and help :) . All of this if for monitoring, and show data in grafana. But i can't find the filesystem "/dev/sda/", for the disk dashboard...

From the documentation about the setting filesystem.ignore_types:

A list of filesystem types to ignore. Metrics will not be collected from filesystems matching these types. This setting also affects the fsstats metricset. If this option is not set, metricbeat ignores all types for virtual devices in systems where this information is available (e.g. all types marked as nodev in /proc/filesystems in Linux systems). This can be set to an empty list ([]) to make filebeat report all filesystems, regardless of type.

If you check the file /proc/filesystems you can see which files are marked as "nodev". Is it possible that ext4 is marked as nodev?

Can you try to set the setting filesystem.ignore_types: [] to see if the file is now considered?
