Prerequisites: Ensure that the NTP service is synchronized before creating recurring discovery tasks. If you update (synchronize) the NTP service after creating discovery tasks, you must edit the task to force rescheduling. This updates the next run time to align with the current system clock and restores normal execution. This workaround addresses an issue where discovery tasks fail to trigger at scheduled intervals when system time moves backward due to NTP updates.

Use the following procedure to create a discovery task:

  1. Select the Tasks tab.
  2. Select New task.
  3. In the Create discovery task window that appears, set the following parameters:
    Note: Parameters marked with an asterisk (*) in the UI are mandatory.
    • Name—enter a unique name for the discovery task. This name is used only for identification within Network Discovery.
    • Probe—from the drop-down list, select the BlueCat Address Manager Server or BlueCat DNS/DHCP Server (on which a discovery probe is enabled) on which the discovery task must run.
      Note: Choose the BlueCat Server that has proximity and access to the devices to be discovered.
    • Discovery policy—from the drop-down list, select the discovery policy you want to assign to the selected probe.
    • Scheduled date—enter a date (in mm/dd/yyyy format) on which the discovery task must run. Alternatively, you can select the calendar icon in this field to select the date.
    • Frequency—select one of the following options to specify how often you want the discovery task to run:
      • Once—the task runs only once (that is, on the scheduled date).
      • Recurring—the task runs at periodic intervals. If you select this option, you must specify the Interval (integer value) between tasks and the Unit (unit of time to use with the interval: Months, Days, Hours, or Minutes).
    • Max discovery results—enter the number of discovery results the task is allowed to store. If the task runs multiple times, the task will contain multiple results, up to the maximum number you specify in this field. For example:
      • If you set the maximum discovery results to 5, the task stores the 5 most recent results. When the task runs for the 6th time, the oldest result is removed.
      • If you set the maximum discovery results to 1, the task will always contain only 1 result (the latest). The result is overwritten each time the task is run.
  4. Select Create to create the discovery task and return to the Tasks table.
Attention: Discovery tasks created using a remote probe remain indefinitely in Running status and never return discovery results after system time moves backward due to NTP updates. To prevent this issue, ensure that the NTP service is synchronized before enabling the Network Discovery & Visibility Feature Module. If you update (synchronize) the NTP service after enabling the Feature Module, you must restart the Network Discovery & Visibility Feature Module. After restart, the scheduled run times for all jobs are calculated from the beginning.
