Debug
Inspect match payloads and rule behaviour without leaving the platform. Add debug to alert: and watch the elastalert logger when troubleshooting rules. Add debug under alert: on your rule (you can combine destinations).
Use Options for key-by-key reference, then Full working example for copy-paste YAML you can tailor to your stack.
Options
Keys below match the ElastAlert 2 alerter. Shared rule fields such as alert_subject apply as described in Subject & body. Example fragments from the ElastAlert 2 reference appear indented under the option they illustrate (add your own name, type, index, and filter to make a full rule).
- No destination-specific YAML keys — add
debugunderalertonly. Output is written to the Python logger namedelastalertat INFO level.
