There are two alert types, scheduled and real-time. Alert type definitions are based on alert search timing. Depending on the scenario, you can configure timing, triggering, and other behavior for either alert type.
Alert type comparison
Here is a comparison of scheduled and real-time alerts.
|Alert type||When it searches for events||Triggering options||Throttling options|
|Scheduled||Searches according to a schedule. Choose from the available timing options or use a cron expression to schedule the search.||Specify conditions for triggering the alert based on result or result field counts. When a set of search results meets the trigger conditions, the alert can trigger one time or once for each of the results.||Specify a time period for suppression.|
|Real-time||Searches continuously.||Per-result: Triggers every time there is a search result.||Specify a time period and optional field values for suppression.|
|Real-time||Searches continuously.||Rolling time window: Specify conditions for triggering the alert based on result or result field counts within a rolling time window. For example, a real-time alert can trigger whenever there are more than ten results in a five minute window.||Specify a time period for suppression.|
