Preview rule alerts generated on specified time range
https://{kibana_url}
- POST /api/detection_engine/rules/preview
- POST /s/{space_id}/api/detection_engine/rules/preview
Refer to Spaces for more information.
Simulates a detection rule using the same rule type and query logic as a persisted rule, over a short
time window, without persisting a rule or writing alerts. Use the response to validate queries, see sample
matching documents, and inspect execution logs. Pair invocationCount and timeframeEnd to cap run time.
Query Parameters
-
enable_logged_requestsboolean Enables logging and returning in response ES queries, performed during rule execution
Request
Rule create payload (same shape as POST /api/detection_engine/rules for a given type) plus
invocationCount and timeframeEnd to control how the preview is executed. Optional
enable_logged_requests surfaces Elasticsearch request logging for debugging.

history_window_startstring · min: 1required -
Start date to use when checking if a term has been seen before. Supports relative dates – for example, now-30d will search the last 30 days of data when checking if a term is new. We do not recommend using absolute dates, which can cause issues with rule performance due to querying increasing amounts of data over time.
