The Shazzam probe is placed in the ECC queue as a first step in horizontal discovery. The ECC queue is a table that stores requests and responses for communication between the MID Server and the ServiceNow instance1. The Shazzam probe is a script that performs port scanning on a target host to determine what protocols are available and what classifiers to trigger2. The Shazzam probe is sent from the ServiceNow instance to the MID Server, which executes it on the target host and returns the results to the ECC queue3.

London Linux Servers is a CMDB Group with Health Group type. A CMDB Group is a collection of configuration items (CIs) that share common characteristics or are related in some way1. A Health Group is a type of CMDB Group that is used to monitor and measure the health of a specific set of CIs based on predefined rules and metrics2. The image shows that London Linux Servers is selected from the CMDB Health Group List, which is a dropdown menu that displays all the Health Groups defined in the system3. The image also shows the Group Health tab, which displays the health scores and indicators for the selected Health Group.

To troubleshoot discovery issues from a discovery status in ServiceNow, the following related lists can be particularly useful:
* Discovery Log - Provides detailed logs of the discovery process, helping to identify errors or issues encountered during discovery.
* ECC Queue - Shows the messages and data passed between the ServiceNow instance and the MID Server, offering insights into the communication and data exchange during discovery.
* Devices - Lists the devices discovered in the process, allowing for a direct view of the results and any potential issues with specific devices.
The "Running Processes" list is not typically used for troubleshooting discovery processes as it relates more to the operational aspects of the server or device rather than the discovery process itself. References = ServiceNow Discovery documentation, specifically the sections on Discovery troubleshooting and analysis, and the use of related lists for monitoring and troubleshooting purposes.
