Let me explain the problem. Im searching for a specific mount in a server (actually is a volume added), 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.
Please help. Thank you for reading
