Good Day,  
I am collecting metric information from my provider and pushing them to ES through a python script. all I need to do is subtract **"MetricName"** , (i.e: Count - 5xx) with respect to time on total system availability.

```
mapping_template = {
    "mappings": {
        "properties": {
            "Namespace": {"type": "keyword"},
            "MetricName": {"type": "keyword"},
            "Dimensions": {"type": "keyword"},
            "Unit": {"type": "string"},
            "Timestamp": {"type": "date_nanos"},
            "Date": {"type": "date"},
            "Statistics": {
                "Sum" : { "type" : "double" },
                "Minimum" : { "type" : "float" },
                "Maximum" : { "type" : "float" },
                "p99" : { "type" : "float" },
                "p95" : { "type" : "float" }
                }
        }
    }
}

```

Sample Data:

> {"Namespace": "AWS/ApiGateway", "MetricName": "5XX", "Dimensions": "requests", "Date": "2021-03-05T10:38:00+00:00", "Timestamp": 1614940680000, "Unit": "Count", "Statistics": {"Sum": 6.0}}

In the bucket, I do not see the option subtract across metric. ("MetricName": "Count" - "MetricName": "5XX").Even with the scripted field, was not able to access multiple docs.

Just wanted to know what is the approach to achieve this.

Thanks
