Create a pattern for host-based serverless discovery

Create a pattern for host-based serverless discovery

To find application CIs that reside on a known host in your CMDB, create an infrastructure pattern for host-based serverless discovery.

Before you begin

Role required: cloud_admin, sm_admin, or admin

Procedure

  1. Navigate to Pattern Designer > Discovery Patterns.
  2. Click New.
  3. Specify an Infrastructure type pattern with the correct CI type that applies to the CIs you want to discover. See Create or modify patterns for an explanation of all form fields.
  4. Create an identification section and save the pattern.
  5. Add operations to the pattern to discover the CI that you can access via the host.
  6. To test the pattern, click Debug Mode and enter the IP address of the host.

What to do next

Use the pattern in a serverless discovery schedule.

Create a Discovery schedule for host-based serverless discovery

After you create a pattern for host-based serverless discovery, create a Discovery schedule and specify the pattern. Discovery triggers the pattern from the schedule rather than from a classifier.

Before you begin

  • Role required: cloud_admin, sm_admin, or admin
  • A pattern for serverless discovery that does not specify input parameters
  • Credentials for the host device that acts as the proxy

Procedure

  1. Navigate to Discovery > Schedules.
  2. Click New.
  3. Select the Serverless in the Discovery field. See Schedule horizontal discovery for explanation of other fields.
  4. Right-click the form header and select Save.
  5. In the Serverless Execution Pattern related list, click New.
  6. Fill out the form fields (see table):
    Field Description
    Name Provide a descriptive name.
    Pattern Select the pattern you created for host-based discovery.
    Proxy Host If you are using host-based discovery, specify an existing CMDB CI. Discovery uses the credentials of this CI when exploring the CIs on the host.
    Active Keep this check box selected to use the pattern execution definition.
  7. Right-click the form header and select Save.
  8. Define as many serverless execution pattern records as needed. You can launch the same pattern, but they should have different parameters.
    Note: You do not need to create entries in the Discovery Pattern Launcher Parameters related list.
  9. Execute discovery by clicking Discover Now or wait until the schedule triggers the discovery.

Result

Check the Discovery status to see the Discovery log, the devices list, which holds the discovered CIs, and the ECC queue records. Note that the Shazzam probe did not launch and Discovery did not trigger any classification probes.
