The ntp module implements the ntp health check. This health check polls a remote (or local) machine via the Network Time Protocol. It reports red if the target machine does not answer NTP requests at all. It reports yellow if the target machine is answering but is not synchronized with its masters/peers. The module requires the ntptrace command to be available on the machine it is running.
