…ic#7986) New metrics are introduced to better track the number of open file descriptors. In the initial issue number of open file descriptors were requested by input. Reporting the number of open files by harvesters is already implemented. It's reported as filebeat.harvester.open_files. I included process level file descriptor information reporting for each Beat which runs on Linux. New metrics beat.fd.open: Number of open files by a Beat process. It's the number of files under /proc/{{ filebeat-pid }}/fd. Only implemented on Linux. beat.fd.limit.soft: Soft limit of the Beat process. Could be used to notify a user if the process is reaching the limit (in the Monitoring UI). beat.fd.limit.hard: Hard limit of the Beat process. It is the max limit that can be set on a host without modifying kernel params. (cherry picked from commit f10096a)
