Report number of handles / file descriptors held by processes

[kinghrothgar]

I am in the process of adding number of file descriptors into metricbeat and or topbeat. After this gets merged elastic/gosigar#30, I want to start implementing it in beats. As it appears metricbeat is just calling topbeat under the hood for most stuff, it seems like I should add it there first and make the needed changes on the metricbeat side?

Currently the best option is to do what you described above. As Topbeat and Metricbeat are in one repo, the changes can go into 1 PR. We plan to move parts of topbeat into gosigar and parts into metricbeat, but it is not clear yet how this will exactly look.

Thanks for your contribution.

@kinghrothgar Just checking in. Are you still pursing this? Is there anything I can do to help?

I opened PR #2257 to add FD usage information to the system.process MetricSet in Metricbeat.

I think the overall system FD usage information could go into a system.info MetricSet if we had one. That MetricSet would report things like OS version, uptime, total FD usage, virtualization info, etc.
