The triggering conditions in the Splunk alerts will work as a secondary search that can evaluate the entire search results of the alerts. If it doesn’t show any results then the alert doesn’t trigger and vice versa.

By depending on all the alert action that we have chosen you can access all the information which may trigger the results. While the secondary search for the trigger condition will not determine the information that can alert the actions. Then the result fields and the remaining information will come from the initial base search.
