Hi @kuppalad 

Which type of classifier you wants to create is application classifier or Device Classifer?

Hi,

Please find the below information:

What is a Discovery Classifier?

A classifier in ServiceNow Discovery determines which probes to trigger for identifying and exploring Configuration Items (CIs). It starts the identification stage after the classification probe returns relevant parameters.

Types of Discovery Classification:

1. Device Classification

   • Identifies device types (e.g., Windows, Linux, routers, switches).
   • Uses active process probes for further exploration.
   • Can classify devices using HTTP, WMI, SSH, or SNMP.

2. Process Classification

   • Classifies applications based on running processes.
   • Occurs in the exploration phase of discovery.
   • Can trigger additional probes and create child CIs.

3. IP Address Classification (IP Scan)

   • Credential-less classification based on open ports and banners.
   • Updates CMDB upon successful classification.
   • Triggers exploration probes for additional details.

Classifier Criteria & Patterns:

• Classifiers have conditions that determine when they trigger based on probe parameters.
• Discovery can use patterns instead of probes to identify and explore CIs via the Horizontal Pattern probe.

When to Modify or Create a Classifier?

• If a classifier isn’t running correctly.
• If Discovery isn’t identifying a specific type of CI.
• If you want to trigger custom probes or modify classification behavior.

For detailed steps, refer to the official ServiceNow documentation:
