This document applies to Classic/Legacy Integrations. You may continue to use these integration configurations. While no active development is happening for these integrations, we continue to provide Classic/Legacy Integrations in the product. You do not have to move to MSI Integrations. If your support engineer or TSC recommends or you choose to move to MSI Integrations, you can take advantage of the latest features and functionality.

(Optional) Update Query time and Delay time.

The Query time is the amount of time (minutes) before and after the query runs that the looks for events, while the Delay time is the amount of time (minutes) that the platform waits to run the query after a Job Action. For example, you configure your integration with the following values: Query time = 5, Query interval = 30 seconds, and Delay time = 0. When a Job Actions starts at 12:00:00, the first time the query runs, the platform looks for events from 11:55:00 to 12:00:00. Then 30 seconds later, it looks for events from 11:55:30 to 12:00:30. This interval continues, with the last query looking from 12:00:00 to 12:05:00. If you instead configured the Delay time to equal 10, it would run the same query, but it wouldn't start that query until 12:10:00.

If your monitors are set to run more frequently than the query time, it will impact the pass/fail results for AEDA monitors.

(Optional) Select Enable query for Malicious DNS Actions and configure the Query. This query will only be used when you run Malicious DNS Actions or Captive DNS Actions.
(Optional) Select Discover network devices automatically.
Modify the Query Interval and Event Time Adjustment, if necessary.
(Optional) Assign a Name.
