You can start either an immediate or a scheduled discovery run by clicking the Add New Run link from the Discovery status page. You can perform the following for a run:

  • Specify the IP range that is scanned during the normal discovery run.
  • Schedule a discovery run to occur at any time and for a specified amount of time. For example, you might want to schedule a scan during off hours to avoid the risk of touching critical applications.
  • Enable or disable individual scheduled discovery runs.
  • Assign a company name to a discovery run.

For immediate runs, you can scan a specified address range right away, whether or not a regular discovery run is in progress. The specified addresses are scanned automatically and as soon as possible.

For general information about the discovery process, see the Discovery Engine.

To scan IP addresses or ranges immediately

  1. On the discovery page, click Add New Run. For Consolidation appliances, click Add New Local Run.
  2. Enter the information for the snapshot discovery run in the fields.

    Field name

    As you enter text, the UI divides it into pills, discrete editable units, when you enter a space or a comma. According to the text entered, the pill is formatted to represent one of the previous types or presented as invalid.

     Click here for more information on using the pill UI.

    Invalid pills are labeled with a question mark. You can also paste a list of IP addresses or ranges into this field. If any pills are invalid, a message stating the number of invalid pills is displayed above the range field. Clicking the link applies a filter which shows only invalid pills which you can then edit or delete. The filter can be removed by clicking clear in the Showing n of n label below the Range field. There is no paste option on the context sensitive (right click) menu.
    Warning: You cannot paste a comma-separated list of IP address information into the Range field in Firefox. This can crash the browser. You can use a space separated list without any problems.
    • To edit a pill, click the pill body and edit the text.
    • To delete a pill, click the X icon to the right of the pill, or click to edit and delete all of the text.
    • To view the unformatted source text, click the source toggle switch. The source view is useful for copying to a text editor or spreadsheet. Click the source toggle switch again to see the formatted pill view.
    Underneath the entry field is a filter box. Enter text in the filter box to only show matching pills.
