I am trying to get total number of file descriptors in the system. According to this resource: https://www.elastic.co/guide/en/beats/metricbeat/current/exported-fields-system.html#_fd
There is a field available to use:
system.process.fd.open
This shows the file descriptors per process.
Question: Is there any way to get all (total/sum) the file descriptors/handles for the system regardless of process? Total number of file descriptors for all the processes.
Please help.
Thanks.
