What is the difference between Identification Section and Extension Section In Discovery Pattern?

[Iraj Shaikh · Accepted solution]

In ServiceNow Discovery, a Discovery Pattern is a set of instructions that define how the system should identify and classify devices on a network. The Identification Section and Extension Section are two key components of a Discovery Pattern, each serving a distinct purpose:

1. Identification Section:

• Purpose: The Identification Section is responsible for defining the criteria to identify a device on the network.
• Functionality: It specifies conditions and probes to determine whether a device matches the pattern. These conditions may include criteria such as IP addresses, device types, or specific characteristics that help in accurately identifying the device.
• Example: In the Identification Section, you might specify that if a device responds to a certain type of ping or has a specific SNMP (Simple Network Management Protocol) profile, it should be classified as a certain type of device (e.g., a router or a printer).
  
  

2. Extension Section:

• Purpose: The Extension Section allows you to gather additional information about a device that has already been identified.
• Functionality: Once a device is identified, the Extension Section is used to run additional probes to collect more detailed information about the device. This information can include details about the device's configuration, installed software, or any other relevant data.
• Example: After identifying a server in the Identification Section, the Extension Section may include probes to retrieve information about the server's operating system, installed applications, or specific configuration details.

In summary, the Identification Section is focused on the initial identification of devices based on specific criteria, while the Extension Section is concerned with gathering additional information about the identified devices. Both sections work together to create a comprehensive Discovery Pattern that enables the system to understand and classify devices on the network accurately.
