Which components does ServiceNow Discovery use to collect and process data within the base system?

ServiceNow Discovery uses Patterns, Probes, and Sensors as its core components to collect and process data.

Patterns are essential for identifying the type of software or device being discovered. They define the rules that determine how specific assets are recognized. This might include the services running on a server or the applications installed on a machine, enabling Discovery to accurately model the infrastructure.

Probes operate as the mechanism for collecting data from the target systems. They gather information about the resources and configurations on those systems and then pass this data on for further processing. Probes can query various resources, helping to ensure that all relevant data is captured during the discovery process.

Sensors are responsible for interpreting the data received from the probes. After probes send back the collected data, sensors analyze and transform that information into meaningful records within the ServiceNow platform. This includes creating and updating configuration items (CIs) in the CMDB (Configuration Management Database).

The combination of these components allows for a comprehensive and efficient discovery process, ensuring that the relevant information about IT assets is accurately collected, processed, and stored. By using Patterns, Probes, and Sensors, ServiceNow Discovery provides an effective framework for maintaining up-to-date records of software and hardware assets in an organization's infrastructure.
