Use a pattern for horizontal discovery

If you already have a pattern that you were using for top-down discovery, you can also use it for horizontal discovery with a few modifications to the relevant classifier.

Before you begin

Role required: discovery_admin

Starting with the Istanbul release, you can use the same pattern for top-down discovery and horizontal discovery to find that same CIs. You must first verify the configuration of the Identification section of the pattern, add or modify the classifier for the CI, and then specify a probe specifically for horizontal discovery through patterns.

Procedure

  1. Verify that the pattern is correct:
    1. Navigate to Pattern Designer > Discovery Patterns.
    2. Open the pattern. Service Mapping patterns are indicated as type 1-Application.
      Two UI actions appear for editing the pattern: Edit for Discovery (for the Discovery application) and Edit for Mapping (for the Service Mapping application).
    3. Click Edit for Discovery. The pattern designer window opens.
    4. In the Identification Sections window, verify that there is at least one section that allows for an entry point type of TCP or All. If not, create one. See the Identification steps for creating a new pattern.
    5. Close the pattern designer.
  2. On the instance, create or modify the classification for the CI type you want to discover. Configure the classifier as follows:
    1. Navigate to Discovery Definition > CI Classification > {classification type}.
    2. Open the relevant classifier or create a new one.
    3. Configure the classifier as follows:
      • Relationship type: Select Runs on::Runs (for process classifiers only)
      • Condition: Configure the same condition you defined in the pattern.
      • Triggers probes Related list: Add the Horizontal Pattern probe, and then add the pattern you are using to the Pattern column.
    See Create a Discovery CI classification for a description of the other fields.

What to do next

Run the pattern in Debug mode to test it. When you are sure the pattern works, you can run discovery by setting up a discovery schedule or running an on-demand discovery. See Create a Discovery schedule for more information.
