osquery

#!/bin/sh
#
# osqueryd 	Start/Stop the osquery daemon.
#
# chkconfig: 2345 90 60
# Description: 
#             With osquery, you can use SQL to query low-level
#             operating system information. Under the hood, instead
#             of querying static tables, these queries dynamically execute 
#             high-performance native code. The results of the 
#             SQL query are transparently returned to you quickly and easily 
#
