Question:
What are alerts in Splunk?
An alert is an action that a saved search triggers on regular intervals set over a time range,
based on the results of the search.
When the alerts are triggered, various actions occur consequently.. For instance, sending
an email when a search to the predefined list of people is triggered.
Three types of alerts:
1.
Pre-result alerts : Most commonly used alert type and runs in real-time for an all-
time span. These alerts are designed such that whenever a search returns a result,
they are triggered.
2.
Scheduled alerts : The second most common- scheduled results are set up to
evaluate the results of a historical search result running over a set time range on a
regular schedule. You can define a time range, schedule and the trigger condition
to an alert.
3.
Rolling-window alerts: These are the hybrid of pre-result and scheduled alerts.
Similar to the former, these are based on real-time search but do not trigger each
time the search returns a matching result . It examines all events in real-time mapping
within the rolling window and triggers the time that specific condition by that event in
the window is met, like the scheduled alert is triggered on a scheduled search.
