Watcher fire once

[Andreas_Marshall]

We ended up using the following without throttle-period. It is working as intended

PUT _xpack/watcher/watch/my-watch
{
  "trigger": {
    "schedule": {
      "interval": "20s"
    }
  },
  "input": {
    "search": {
      "request": {
        "indices": [
          "test-*"
        ],
        "body": {
          "query": {
            "bool": {
              "must": {
                "match": {
                  "level": "Error"
                }
              },
              "filter": {
                "range": {
                  "@timestamp": {
                    "from": "{{ctx.trigger.scheduled_time}}||-25s",
                    "to": "{{ctx.trigger.triggered_time}}"
                  }
                }
              }
            }
          }
        }
      }
    }
  },
  "condition": {
    "compare": {
      "ctx.payload.hits.total": {
        "gt": 0
      }
    }
  },
  "actions": {
    "send_email": {
      "email": {

        "subject": "Watcher Notification",
        "body": "{{ctx.payload}}",

      }
    }
  }
