The attribute responsible for de-duplication is 'Message_key'. De-duplication in systems is typically performed using unique identifiers that distinguish between different messages or events, preventing the same data from being processed multiple times. 'Message_key' serves this purpose by acting as a unique identifier for each message, ensuring that duplicates can be identified and handled accordingly.

The default collection/polling interval applied to all event connectors is every 120 seconds. This is a common interval that provides a balance between timely event monitoring and system resource usage. Other intervals, such as 5, 10, 40, or 60 seconds, may be too frequent and can lead to performance issues or unnecessary resource consumption.

To determine what event rule created an alert, you can check the Alert Activity and Event Processing Notes. Alert Activity provides the history and details related to the alert which often includes information about the rule that triggered it. Event Processing Notes typically contain detailed logs and notes regarding the processing of the event, including which rule was used to create the alert.

Event rules are used to trigger workflows and automatically generate tasks via templates. They are specifically designed to manage and respond to various events, making them suitable for automating processes based on specific conditions.
