ServiceNow CIS-Discovery Actual Questions

Debug mode is a feature of the Pattern Designer that allows you to test and troubleshoot your patterns in real time. To activate Debug mode, you need to have the admin role or a role that includes the pattern_designer_debug permission. Debug mode is not available for users who only have the pattern_designer_read permission1.

The ECC Queue is the normal connection point between an instance and other systems that integrate with ServiceNow, such as MID Servers1. The ECC Queue displays input and output messages from and to MID Servers2. The actual XML payload that is sent to or from an instance is stored in the ECC Queue3. The ECC Queue also provides a connected flow of probe and sensor activity, as probes are sent from the instance to the MID Server, and sensors are sent from the MID Server to the instance2.

The Extension section in a horizontal pattern is executed after the Identification sections have completed and the CI has been identified. The Extension section allows adding additional attributes or relationships to the CI, or launching other patterns for further discovery12.

The default thread count for a MID Server is 25. This means that the MID Server can run up to 25 worker threads simultaneously to execute the jobs assigned to it by the ServiceNow instance. The worker threads are divided into different thread pools based on the priority of the jobs. The MID Server can also adjust the thread count dynamically based on the system resources and the workload. The thread count can be configured by changing the MID Server parameters in the ServiceNow instance12. References = 1: MID Server Max Threads - Worker Groups - Priority and Queues - ServiceNow 2: Product Documentation | ServiceNow
