What format is used to embed field values in the title, description, and drill-down fields of a notable event during custom correlation searches?

The format used to embed field values in the title, description, and drill-down fields of a notable event during custom correlation searches in Splunk is indicated by the use of $fieldname$. This syntax allows for the dynamic inclusion of field values directly within these text fields, enabling the creation of informative and context-rich notable events.

When a notable event is generated, the fields referenced with this syntax are replaced with their respective values from the search results. This capability makes it easier for users to understand the significance of the notable event, as it can provide real-time and relevant data directly within the event details. For example, if you have a field called "username," embedding it as $username$ in the title would display the actual username associated with the notable event when the event is generated.

Understanding this format is crucial for effective event management and can enhance the overall utility of correlation searches within the Splunk environment.
