Schedule a horizontal discovery

A discovery schedule determines what horizontal discovery searches for, when it runs, and which MID Servers are used. Create a discovery schedule for your local environment or a schedule for discovering the resources in your cloud service account.

Before you begin

Ensure that your discovery schedule conforms to security best practices, such as limiting the range of discovery targets and using the most secure credentials.

Make sure to test your credentials before you run a schedule. Bad credentials are a leading cause of failed discoveries.

Roles required: discovery_admin or admin

About this task

You can use a discovery schedule to launch horizontal discovery, which uses probes, sensors, and pattern operations to scan your network for CIs. Use this procedure to create a schedule manually from the Discovery Schedules form.

Service Mapping also provides a discovery schedule for top-down discovery. See Schedule a top-down discovery by Service Mapping for more information.

Use the Discovery Schedules module in the Discovery application to:

• Configure a schedule to discover resources in your cloud service account.
• Configure a schedule to discover certificates from URL scans.
• Configure device identification by IP address or other identifiers.
• Determine if credentials are used in device probes.
• Name the MID Server to use for a particular type of discovery.
• Create or disable a schedule that controls when the discovery runs in your network.
• Configure the use of multiple Shazzam probes for load balancing.
• Configure the use of multiple MID Servers for load balancing.
• Run a discovery schedule manually.
• Run a discovery on a single IP address.

Note:

To view the run-results of your schedules for both IP-based and Cloud Discovery, use the summaries on the Discovery Home page. The Home page publishes the details of any errors that might have occurred and displays possible actions to take to remediate problems.

Procedure

1. Navigate to All > Discovery > Discovery Schedules to create a new record.
2. Select the type of schedule to open:
   • New: Creates a new horizontal schedule for discovering components in your network.
   • Quick Discovery: Runs a horizontal discovery on a single IP address without requiring a schedule.
   • Create a Cloud Discovery schedule: Creates a schedule, using the Discovery Manager wizard, for discovering resources in a cloud service account.
3. Complete the discovery schedule form, using the fields in the table.
   For more information, see Discovery Schedule form reference.
4. Right-click in the header of the record and select Save from the context menu.
5. To create a range of IP addresses to discover, click Quick Ranges under Related Links.
   Note:

   To improve security, limit the range of discovery targets to exclude unnecessary networks and devices.
6. Define the frequency of schedule running as described in Run options for discovery schedules.
