Status Monitoring via the Web UI

While the SecureSync front panel status LEDs provide an indication of the current operating status of the system (see Status Monitoring via Front Panel), more detailed status information can be accessed via the SecureSync Web UI, such as:

  • Time synchronization status, including references
  • GNSS satellites currently being tracked
  • NTP sync status and current Stratum level
  • Estimated time errors
  • Oscillator disciplining
  • Temperature monitoring
  • Status of outputs and presence of DC input power.

The HOME screen provides time server status information, while the TOOLS > System Monitor screen also displays hardware status data, e.g. temperature curves:

Status Monitoring via the HOME Screen

The HOME screen of the SecureSync Web UI provides a system status overview (see also The Web UI HOME Screen).

The HOME screen is divided into four panels:

ClosedSystem Status panel
  • Reference—Indicates the status of the current synchronizing reference, if any.
  • Power—Indicates whether the power is on and which type of power is being used. If the unit is configured for AC power, AC will appear in this panel. If the unit is configured for DC power, DC will appear in this panel. If the unit is configured for both AC and DC, AC and DC will appear in this panel.
  • Status—Indicates the status of the network’s timing. There are three indicators in the Status field:
    • Sync—Indicates whether SecureSync is synchronized to its selected input references.
      • Green indicates SecureSync is currently synchronized to its references (the front panel Sync light will also be green).
      • Orange indicates SecureSync is not currently synchronized to its references (the front panel Sync light will be red).
    • Hold—When lit, SecureSync is in Holdover mode.
    • Fault—Indicates a fault in the operation of the SecureSync. See Troubleshooting via Web UI Status Page for instructions for troubleshooting faults.
  • Alarm Status: If a major or minor alarm is present, it will be displayed here.
  • NTP—Current STRATUM status of this SecureSync unit.
  • Temperature—The current board temperature will be displayed here, plus—depending on product configuration—oscillator, and CPU temperatures, as well. For more information, see Temperature Management.
ClosedReference Status panel
  • REFERENCE: Indicates the name type of each reference. These are determined by the inputs set up for the SecureSync
  • PRIORITY: Indicates the priority of each reference. This number will be between 1 and 15. References in this panel appear in their order of priority. See Configuring Input Reference Priorities for more information.
  • STATUS: Indicates which available input reference is acting as the Time reference and which available input reference is acting as the 1PPS reference.
    • Green indicates that the reference is present and has been declared valid.
    • Orange indicates the input reference is not currently present or is not currently valid.
  • PHASE: The measured time interval error ("TIE") between the internally disciplined 1PPS and the selected external 1PPS reference.
ClosedPerformance panel
  • Disciplining State—Indicates whether or not the internal oscillator is currently being disciplined (steered to an input reference).
  • 1PPS Phase Error—An internal measurement (in nanoseconds) of the internal 1PPSs’ phase error with respect to the selected input reference (if the input reference has excessive jitter, phase error will be higher)
  • 10 MHz Frequency Error—An internal estimated calculation (in Hertz) of the internal oscillator’s frequency error, based on the phase accuracy error at the beginning and end of a frequency measurement window (the length of this window will vary depending upon the type of oscillator installed and the oscillator adjustment algorithm).
ClosedEvents panel

The Events panel in the bottom-left corner of the HOME screen is a log of SecureSync’s recent activity. It updates in real time.

Note: If you know the individual reference or output whose status you wish to see, you can access the Status window of that reference or output directly through the INTERFACES > REFERENCES or INTERFACES > OUTPUTS drop-down menu.

Status Monitoring via the System Monitor Screen

To display status information pertaining mainly to SecureSync's current hardware status, navigate to TOOLS > SYSTEM > System Monitor.

The information provided on the System Monitor Screen is subdivided into three panels:

ClosedSystem Status panel

This is identical with the HOME screen System Status panel.

ClosedDisk Status panel

This panel displays:

  • Total: [MB]
  • Used: [MB]
  • Free: [MB]
  • Percent: [%]

The last item refers to system storage. If you need to update the System Software, and this number is 70% or higher, it is recommended to clear logs and stats in order to free up memory space. (Navigate to TOOLS > SYSTEM: Upgrade/Backup, and click the corresponding buttons in the lower left-hand corner.)

ClosedSystem Monitor panel

Graphs are displayed for:

  • Board Temperature
  • CPU Temperature
  • Memory Used
  • CPU Used.

To delete the logged data used to generate the displayed graphs, click the TRASHCAN icon. (Note that re-populating the graphs with fresh data generated at a 1/min. rate will take several minutes.)

To download the logged data in .csv format, click the ARROW icon.
