osquery seems like a great candidate for a collector.
Seems like could be another good way for a netdata user to use osquery for scheduled custom queries that osquery could run and manage and then have them available for visualisation in netdata dashboard.
Also would open up collecting anything osquery has has available and implemented that netdata might not have available for whatever reason.
