Watcher condition against buckets

Elastic Stack Elasticsearch

I need to be able to write a condition for a watcher that will alert when the results from the Bucket Critical doc_count is at 50% or higher of bucket Info doc_count

This is the aggregation results

  "aggregations" : {
    "level" : {
      "doc_count_error_upper_bound" : 0,
      "sum_other_doc_count" : 0,
      "buckets" : [
        {
          "key" : "INFO",
          "doc_count" : 662
        },
        {
          "key" : "Critical",
          "doc_count" : 5
        }
      ]
    }
  }

this can be done with a script condition that accesses the fields in the aggregations.level.buckets array and then divides the both doc_count fields from each other (make sure to figure out the order first to not accidently switch dividend/divisor).

If you share what you tried so far, we can take a look at improving your script. As a start there is the examples repo where you can take a look at a few scripts.
