Hi All,

Is it possible to access specific fields within Action boxes under Alerts in Kibana.

For example, I want to alert when the field "host.status" equals down. This is easy using the Elasticsearch Query. After this query matches, I need to send an email with the various info.

I have a field called "host.url" which contains the URL of the hosts. I am struggling on how I can access and bring this field into the message text box under action.

This was previously possible with watcher so I am thinking it should be possible here.  
I am running Elastic/Kibana 7.13.4, trying to migrate away from watcher.

Thanks

Hi @bevano,

If you are using the Elasticsearch Query alert, you should be able to use mustache syntax to access document information inside your action. Documentation is available here: [Elasticsearch query | Kibana Guide [master] | Elastic](https://www.elastic.co/guide/en/kibana/master/rule-type-es-query.html#_add_action_variables_2)

The documents are available within the `context.hits` context variable, which is an array containing the matching documents. In order to access a field like `host.status`, try something like this:

```auto
{{#context.hits}}
Host URL {{_source.host.url}} matched!
{{/context.hits}}

```

Hope that helps!
