Discovery Patterns

[ChittiS]

Hello Everyone,

I'm trying to understand the difference between sn_discovery_patterns and sa_pattern. Both appear to point to the same Pattern table, so I'm curious about their specific purposes and use cases.

Could someone help clarify the distinction?

Thanks!

Hi @ChittiS,

"Patterns of all types are stored in the Discovery Patterns [sa_pattern] table."

So, sa_pattern is the actual table where Discovery and Service Mapping patterns are stored.

The sn_discovery_patterns name is associated with the Discovery and Service Mapping Patterns application/scope, whereas sa_pattern is the underlying table that contains the pattern records.

"Patterns of all types are stored in the Discovery Patterns [sa_pattern] table."

• sa_pattern = Discovery Patterns table (stores the pattern records)
• sn_discovery_patterns = Discovery and Service Mapping Patterns application/scope

For Pattern Designer, Discovery Patterns, and Service Mapping Patterns, the records are ultimately stored in sa_pattern.

Hi @ChittiS 

ServiceNow Discovery Patterns are script-driven workflows used by ITOM Visibility to detect infrastructure, applications, and their dependencies in the network. They replace traditional JavaScript-based probes/sensors with a visual Pattern Designer to efficiently populate and maintain Configuration Items (CIs) in the CMDB. 

The sa_pattern table in ServiceNow is the central administrative interface for managing and executing Discovery and Service Mapping Patterns. It functions as the primary repository for the code that instructs the MID Server on how to identify and classify Infrastructure and Application CIs.
