Hi All,

I want to execute a file. When no logs on specific time, I want email alert.  
Is this possible through watcher?

When there is no data found, I can't get any email alerts.

Yes.  
[https://www.elastic.co/guide/en/x-pack/current/condition-compare.html#\_using\_a\_compare\_condition](https://www.elastic.co/guide/en/x-pack/current/condition-compare.html#_using_a_compare_condition)

The condition below would execute any of the watch actions when the search result return less than or equal to 0.

```auto
{
  "condition" : {
    "compare" : {
      "ctx.payload.hits.total" : { 
        "lte" : 0
      }
  }
}

```
