System monitoring with osquery

As administrator I could say one thing: Never ever use ControlMaster for monitoring purposes. ControlMaster works well if servers and networks work well. But monitoring should continue to work even there are some nasty things happen with network and hosts. If previous TCP connection stuck in oblivion due to stalled contrack, or RST which was lost in turbulence, ControlMaster will cause massive false positives, distracting people from actual issues, or even masking actual problems on hosts by mundane 'network glitch' issue.
