Creating a Watcher Rule

[Elk_huh (Brian)]

I am new to watcher rules and need some guidance

How do i write a watcherrule to

Look at an index at a specific field to see if a value = B

If value = B

{
  "trigger": {
    "schedule": {
      "interval": "1m"
    }
  },
  "input": {
    "search": {
      "request": {
        "search_type": "query_then_fetch",
        "indices": [
          "metricbeat*"
        ],
        "types": [],
        "body": {
          "size": 0,
          "query": {
            "match": {
              "beat.version": "6.2.4"
            }
          }
        }
      }
    }
  },
  "actions": {
    "send_email": {
      "email": {
        "profile": "standard",
        "to": [
          "email"
        ],
        "subject": "found beats version",
        "body": {
          "html": "found beats version"
        }
      }
    }
  }
}

I have this but its not working as expected

This looks good, but one step is missing. You only want to sent that email, if you really found any hits. This needs to be put into a condition, probably a script condition. See https://www.elastic.co/guide/en/elasticsearch/reference/7.6/condition.html
