Set up error transaction percentage alert email

Hi @spinscale, I did it with bucket_script:

"success_percent": {
                  "bucket_script": {
                    "buckets_path": {
                      "error": "group_by_count_err",
                      "total": "group_by_count_all"
                    },
                    "script": "params.error/ params.total* 100",
                    "format": "0.00"
                  }
}

But I get all NAME values, how can I set the warning threshold for each NAME. For example: NAME 1: 80%, NAME 2: 20%... If the percentage is greater than the threshold, the NAME value will appear in the alert email.
