Kibana 不发送有关新数据的警报

Question

I have an Alert setup on Kibana (v7.1.1) for sending an alert whenever an OutOfMemory log is encountered. The trigger is setup with severity 2 to send alert to a list of email with Throttle actions to only trigger every 5mins . This alert creates a trigger after 10 mins from the creation time and keeps sending alert until I click Acknowledge it. Once I click Acknowledge the trigger is not generated ever again even though OOM logs are being generated.

I want this to send alert whenever a new OOM log is encountered and stop for next 5 mins (by enabling throttling) if OOM logs still keep generating. Following are the monitor details:

Monitor Name : OOM Alert

Schedule : By interval every 5mins

Define Monitor : Define using extraction query

    "query": {
        "bool": {
            "must": [
                {
                    "range": {
                        "@timestamp": {
                            "from": "{{period_end}}||-1d",
                            "to": "{{period_end}}",

                            "boost": 1
                        }
                    }
                }
            ],
            "should": [
                {
                    "wildcard": {
                        "log": {

                            "rewrite": "constant_score",
                            "boost": 1
                        }
                    }
                }
            ],
            "adjust_pure_negative": true,
            "boost": 1
        }
    }
}

can you try to change the date filter to this:

   "range": {
              "@timestamp": {
                "gte": "now-16h",
                "lt": "now"}}
