While working with DX UIM Dev Team on a troubleshooting call for new version of NTP probe we were getting error unable to contact host for which dev team told us to enable Ping from server to ntp server so we are trying to get ping enabled but Client network team wants kb or written confirmation why ping should be enabled for this to work.

Can somebody from Dev team confirm on why ping is required from Server to ntp server so that we can submit that to network Team.



  • UIM: 20.4
  • ntp_response v1.43


  • ntp_response Network Time Protocol Response Monitoring tests Network Time Protocol responses by requesting status information from the NTP server.
  • Network Time Protocol (NTP) is a protocol designed to time-synchronize a network of machines.
  • NTP runs on User Datagram Protocol (UDP), which in turn runs on IP.
