Discovery Home page

The Discovery Home page provides a summary of discoveries that were triggered by cloud and non-cloud schedules. You can view any errors that occurred during a Discovery and find remediation suggestions. Use the Home page view to examine the cloud resources discovered for the service accounts you selected in a cloud schedule.

To open the Discovery Home page, navigate to Discovery > Home. The Home page shows the Discovery totals for each of the following categories. Click a tile to see details for that category.

Resolve CI Discovery Schedule errors

From the ServiceNow Home page, you can view the Discovery errors that occurred during a Discovery and get suggestions for resolving these errors. You can view the errors for all schedules or for a single schedule.

Before you begin

Role required: discovery_admin

Procedure

  1. Navigate to Discovery > Home.
    The summary page for all schedules appears.
    CI schedule summary
  2. View the errors, using one of these methods:
    • Click the Errors tile to see the errors by category for all CI discovery schedules.
    • Click the Schedules tile to display the errors for a single schedule.
      1. In the summary screen, select the schedule that you want to investigate for errors.

        If you have numerous schedules, you can filter by location, using the location dropdown list, or filter by the schedule name in the Search by name field.

      2. After you select the schedule, click the Errors tile.
      3. Scroll down to view the errors by category.
        Errors by category for a schedule
  3. Click a category tile to display the specific error codes that occurred in that category.
  4. Click the tile for the error code you want to investigate.
    Errors by category
    The list displays all occurrences of that error code, either for a single CI schedule or for all schedules, depending on the path you took to view the errors. The list shows the IP address of each instance that experienced the error and the error status Active error. The Recommended Actions pane on the right contains the recommended action for the selected error. The ACTION ON ALL pane contains operations you can execute on all the errors in the list.
  5. Click View instructions to see details and remediation suggestions for the error code.
    Error details and remediation instructions
  6. To begin work, either select the check box next to an error to resolve that specific error or select an action for ALL to resolve that error code for all instances of that error.
    In this example, the system recommends creating new Windows credentials to resolve this error code.
    Error detail and recommended actions
  7. Complete the suggested remediation tasks before attempting to retry Discovery.
    In this example, the Create new Windows Credentials link opens a form for creating and testing new Windows credentials.
    Create new Windows credentials
  8. After all the recommended tasks are complete, click Retry Discovery.
    A possible course of action might be to retry Discovery for ALL instances after creating the credentials. The new credentials might solve the issue for all the instances experiencing this error code.
  9. Check the Error Status column to see the results of your remediation efforts.
    Single retries complete quickly. Retries for large numbers of IP addresses can take several minutes.

    An error can have one of these statuses:

    • Active error: Unresolved error. This is the default status of all new errors.
    • Resolved: Resolved error. The recommended actions show Error successfully resolved.
    • Assigned: Task assigned to resolve this error. Click Create a task to assign a user to a task for all active errors. Assigned errors are considered Active errors, and actions can still be performed on them.
    • Pending Discovery: Waiting for Discovery to start after you execute the Retry Discovery action on all errors.
    • In Discovery: Discovery is currently active.
