Round value in alert message

Plugins Alerting

Hello All,

We are trying achieve math round on aggregated results from monitor in alert message.
Here is our Monitor Response:

{
    "_shards": {
        "total": 1,
        "failed": 0,
        "successful": 1,
        "skipped": 0
    },
    "hits": {
        "hits": [],
        "total": {
            "value": 124,
            "relation": "eq"
        },
        "max_score": null
    },
    "took": 5,
    "timed_out": false,
    "aggregations": {
        "route": {
            "doc_count_error_upper_bound": 0,
            "sum_other_doc_count": 0,
            "buckets": [
                {
                    "avg_responsetime": {
                        "value": 57.06632846593857
                    },
                    "doc_count": 64,
                    "key": "Direct"
                },
                {
                    "avg_responsetime": {
                        "value": 98.60404980977377
                    },
                    "doc_count": 60,
                    "key": "Indirect"
                }
            ]
        }
    }
}

The Trigger Message we are trying is – Actual : {{ctx.results.0.aggregations.route.buckets.0.avg_resp.value}} Secs
This results like Actual : 73.47249984741211 Secs.
But the results expected is Actual : 73.47 Secs

Please any one help me how to get round in painless code / Mustache / Monitor Query.

I found work around for this with bucket_script aggregation on existing aggregation in Monitor DSL Query.

{
  "size": 0,
  "aggs": {
    "transaction": {
      "terms": {
        "field": "TransactionName.keyword",
        "size": 10
      },
      "aggs": {
        "avg_resp": {
          "avg": {
            "field": "ResponseTime"
          }
        },
        "avg_resp_f": {
          "bucket_script": {
            "buckets_path": {"v1":"avg_resp"},
            "script": "Math.round(params.v1*100.00)/100.00"
          }
        }
      }
    }
  }
}
