NTP Status Monitoring

NetClock's NTP Status Summary provides a means to monitor NTP status and performance parameters relevant to your NetClock at a glance.

  1. To access the NTP Status Summary panel, navigate to MANAGEMENT > NETWORK: NTP Setup.
  1. The NTP Status Summary panel is at the lower left of the screen. The panel contains the following information:
    • Selected Ref—The reference NetClock is currently using.
    • Stratum—This is the stratum level at which NetClock is operating.
    • Leap Indicator—The leap indicator bits (usually 00). See Leap Second Alert Notification.
    • Delay (ms)—The measured one-way delay between NetClock and its selected reference.
    • Time Offset—This is a graphical representation of the system time offset over time. Clicking on this graph in the NTP Status Summary panel will open a window in the main panel containing a larger, more detailed view of the graph. See The NTP Time Offset Performance Graph.
    • Offset (ms)—Displays the configured 1PPS offset values.
    • Frequency Offset—This is a graphical representation of the system frequency offset over time. Clicking on this graph in the NTP Status Summary panel will open a window in the main panel containing a larger, more detailed view of the graph. See The NTP Frequency Offset Performance Graph.
    • Jitter (ms)—Variance (in milliseconds) occurring in the reference input time (from one poll to the next).
    • Jitter—This is a graphical representation of the system jitter over time. Clicking on this graph in the NTP Status Summary panel will open a window in the main panel containing a larger, more detailed view of the graph. See The NTP Jitter Performance Graph.

    Note: This panel is updated every 30 seconds, or upon clicking the browser refresh button.
