In Elastalert schedule interval option is missing

Question

In Kibana watcher alerts it's possible to fully control the alert schedule using trigger.

{
  "trigger": {
    "schedule": {
      "interval": "2m"
    }
  },

However in elastalert there is no dedicated feature but only to use which aggregate alerts and send

aggregation:
  hours: 2

There is an open issue https://github.com/Yelp/elastalert/issues/1895 If someone know any viable way or an hack to solve this , please let me know.

Answer 1

In ElastAlert v0.2.2, they have provided a limit_execution feature. In that we can define a cron expression. Since I wanted to run at every 15 minutes , I used 0/15 * * * *.

 limit_execution: "0/15 * * * *"
