Calculations inside ES Query

[bpax51]

So I have to following query that gives me to count of successful and failed http queries using aggregations.

{
    "size": 0,
    "query": {
        "bool": {
            "filter": [
                {
                    "match_phrase": {
                        "protocol": {
                            "query": "http"
                        }
                    }
                },
                {
                    "bool": {
                        "should": [
                            {
                                "match_phrase": {
                                    "destination": {
                                        "query": "75.124.145.217"
                                    }
                                }
                            },
                            {
                                "match_phrase": {
                                    "destination.domain": {
                                        "query": "75.124.145.218"
                                    }
                                }
                            }
                        ],
                    }
                },
                {
                    "range": {
                        "@timestamp": {
                            "from": "now-1d",
                        }
                    }
                }
            ],
        }
    },
    "aggregations": {
        "tot_success": {
            "filter": {
                "term": {
                    "http.response.status_code": {
                        "value": "200"
                    }
                }
            }
        },
        "tot_error": {
            "filter": {
                "bool": {
                    "must_not": [
                        {
                            "term": {
                                "http.response.status_code": {
                                    "value": "200"
                                }
                            }
                        }
                    ]
                }
            }
        }
    }
}

That result is like the following:

{
    "_shards": {
        "total": 320,
        "failed": 0,
        "successful": 320,
        "skipped": 315
    },
    "hits": {
        "hits": [],
        "total": {
            "value": 821,
            "relation": "eq"
        },
        "max_score": null
    },
    "took": 815,
    "timed_out": false,
    "aggregations": {
        "tot_success": {
            "doc_count": 809
        },
        "tot_error": {
            "doc_count": 12
        }
    }
}

I was wondering if there is anyway I can make mathematical calculations with the aggregations result and get a result within the same query.

For example calculating the ratio of tot_error/tot_success.

I looked around and found that bucket script might be the solution to my problem, but to be honest I couldn't manage to implement it in my previous query

Can someone help me achieve this.

Would you be able to provide the example query with bucket_script that you came up with? I believe you'd want to do something similar to this example: calculate ratio between aggregation buckets · Issue #16040 · elastic/elasticsearch · GitHub
