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.

Avant de commencer
Role required: discovery_admin
Procédure
Navigate to All > Discovery > Home.
The summary page for all schedules appears.
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.
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.
After you select the schedule, click the
Errors tile.
Scroll down to view the errors by category.
Click a category tile to display the specific error codes that occurred in that
category.
Click the tile for the error code you want to investigate.
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.
Click View instructions to see details and remediation
suggestions for the error code.
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.
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.
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.
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.
