Rescan options enable you to refine scanning behavior associated with certain active monitors including interface active monitors. These options are most useful when performing rescan on selected batches or groups of devices.

  • Basic Rescan. When a basic rescan of a device is initiated, the Primary Role will not change unless previously set to Device or Managed Device and a more appropriate role is found. New sub roles are considered if scan rules match. Please see Defining Device Scan Rules for Device Detection for additional information. Nothing is removed from the device.
  • Advanced Rescan. When an advanced rescan of a device is initiated, Basic Rescan rules apply PLUS, any existing sub roles applied to the device, whose scan criteria does NOT match the device, will be updated.
  • Update Inventory Data. Enabled by default, this option removes and rescans the device(s) inventory data for the specified time period. This ensures that inventory information is kept up-to-date which can impact map calculations, monitoring and reports, among other device-specific areas of WhatsUp Gold. Please see About Inventory Data for additional information about Inventory Data.
  • Update Interface & SNMP Table Monitor Names & Comments. If selected during a basic or advanced rescan, this option will update monitor names and comments from Active Interface or SNMP Table Monitors if they have changed on the device since the last scan.
  • Enable/Disable Interface and SNMP Table Monitors. By default, WhatsUp Gold will only enable Interface Monitors on a device that are operationally Up during a scan of the device. If an interface is operationally Down, then a monitor will be added, but disabled. If an interface that was operationally down during the initial discovery is now up, by running a basic or advanced rescan with this option selected, the monitor will get enabled.
  • Apply 'Use in rescan'. Selecting this option will cause any applicable Active Monitor with the ‘Use in Rescan’ setting enabled to be added to the device.
