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 DiscoveryHome. The Home page shows the Discovery totals for each of the following categories. Select a tile to view details for that category.  
Note:  
Discovery Admin Workspace provides an updated experience for monitoring discoveries, managing schedules, and resolving errors. For more information, see [Discovery Admin Workspace Home](https://servicenow-prod.fluidtopics.net/S3Pog0Mc2M3L6juI_wAO3A "The Discovery Admin Workspace Home page features tools to help you identify and address the most critical discovery tasks.").

## Viewing all schedules {#discovery-home-page__section_jkw_dxr_fbb}

The schedule view displays details for each schedule that ran for the selected filter. By default, the list shows all of the active Discovery schedules in alphabetical order, regardless of their current running status.  
Note:  
You can also monitor and manage IP and cloud-based schedules in [Discovery Admin Workspace Schedules](https://servicenow-prod.fluidtopics.net/fgy9HP9UHPcfjdhZxYla9g "The Schedules page provides a single place to monitor Discovery performance, efficiently manage schedules and statuses, and set up new IP-based or Cloud Discovery schedules.").  
Use these controls to filter Discovery results by schedules:

Schedule filters
:   You have the choice of these filters:

    * All: Results of all Discovery schedules that ran. This is the default filter.
    * Cloud Schedules: Results of all Cloud Discovery schedules that ran. When you select this filter, a second filter appears, allowing you to display cloud schedules by Service Account.
    * IP Based Schedules: Results of all Discovery schedules that ran for Configuration Items (CI), using IP ranges. When you select this filter, a second filter appears, allowing you to display the CI schedules by a specific location or all locations. ![IP-based schedule filters]()
    {#discovery-home-page__ul_slj_fqh_3hb}

Schedule sorter
:   From the schedule selector in the left pane, select a sorting criteria, from left to right: ![Schedule sorting selections]()

    * Errors for each schedule listed.
    * Unidentified IP addresses.
    * Recent activity, which lists the schedules that are currently running first.
    * Alphabetical listing of schedules.
    {#discovery-home-page__ul_vhf_q33_jbb}

Schedule list
:   List of available Discovery schedules. Select a schedule to display its details. Select the pencil icon at the top of the page to edit the schedule.

:   Tiles that show the Discovery result categories for the selected schedule. Select a tile to see more detail.

    * Cloud resources: Displays the total number of CIs updated or created for this filter.
    * Virtual Machines: Displays the total number of virtual machines discovered with the selected schedule.
    * Errors: Displays the total number of errors that occurred from running the selected schedule.
    * Datacenters: Displays the number of datacenters selected during the creation of the Discovery schedule.
    {#discovery-home-page__ul_v2h_sgh_3hb}

Cloud resources trend chart
:   Trend graph for the selected schedule. Each circle in the graph represents a specific Discovery run.  
    Place the cursor over any circle to see a summary of that discovery. ![Resource trend chart detail]()

    Select the circle to filter the values you see in the Discovery topics. The results populate the appropriate tiles above the graph.

Errors by category
:   Category tiles for the errors encountered during the Discovery for the selected schedule. Select a tile to view the errors in that category and to see recommended actions for remediation. See [Discovery error messages](https://servicenow-prod.fluidtopics.net/vaG8ZoYAwrew~W2WRb8BXQ "Review common Discovery error messages and their causes to identify and resolve issues that occur during discovery runs.") for additional details.

## Viewing IP-based schedules {#discovery-home-page__section_egz_j3v_w2b}

To display results from IP range discoveries, select IP Based Schedules in the primary filter. Use the secondary field that appears to filter the search results by Location. The tiles show the result categories for the selected IP-based schedule. Select a tile to see more detail.

* Discovered devices: Total count of virtual machines discovered by the IP-based schedule, including both targeted and unidentified IP addresses.
* Errors: Displays the total number of errors encountered running the selected IP-based schedule.
* Unidentified IPs: Count of unidentified CIs discovered by the IP-based scheduled.
* Targeted IPs: Count of CIs found that were configured in the IP-based schedule.

## Resolve CI Discovery schedule errors {#ariaid-title2}

View and resolve Discovery errors from the ServiceNow Home page. Get suggestions for fixing errors and filter by all schedules or a single schedule.

### Before you begin

Role required: discovery_admin  
Note:  
You can also investigate and resolve Discovery errors in Discovery Admin Workspace. For more information, see [Discovery Admin Workspace Diagnostics](https://servicenow-prod.fluidtopics.net/cbs6_Tu_nYSFXRefm2fqJw "The Diagnostics page helps you prioritize and address errors and anomalies in IP-based and Cloud Discovery schedules. Resolve issues by creating error tasks, tracking progress, and using support tools and logs.").

### Procedure

1. Navigate to AllDiscoveryHome.  
   The summary page for all schedules appears.  
2. View the errors, using one of these methods:  
   * Select the Errors tile to see the errors by category for all configuration item (CI) discovery schedules.
   * Select 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 drop-down list, or filter by the schedule name
        in the Search by name field.

     2. After you select the schedule, select the Errors tile.
     3. Scroll down to view the errors by category.
     {#view-ci-discovery-schedule-errors__ol_znv_kym_rdb}
   {#view-ci-discovery-schedule-errors__ul_xxx_kjr_hbb}
3. Select a category tile to display the specific error codes that occurred in that category.
4. Select 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.
5. Select View instructions to see details and remediation suggestions for the error code.  
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.
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.
8. After all the recommended tasks are complete, select 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. Select 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.
