Hi,

I am using filebeat to ship logs to logstash, and creating index. Now while visualising logs from kibana there are many unwanted fields i am seeing like agent.id, cloud.account.id. I want to remove all the fields. I want to see only message agent.hostname.

i tried using remove\_field which specified [here](https://www.elastic.co/guide/en/logstash/current/plugins-filters-mutate.html#plugins-filters-mutate-remove_field)

```auto
filter {
      mutate {
        remove_field => ["agent.%{somefield}"]
      }
    }

```

but still i see fields in the kibana dashboard.

Hi,

In the documentation you can find :

- `If the event has field "somefield" == "hello" this filter, on success, would remove the field with name "foo_hello" if it is present.`

If the field `somefield` do not exist, no field will be deleted.  
In your case, something like this would be enough.

```auto
filter {
      mutate {
        remove_field => ["agent.id", "cloud.account.id"]
      }
    }

```

Cad.

Thank you.  
I tried with agent.id. Still seeing this values in kibana.  
I have restarted logstatsh after modifying conf file.

You might want try a prune filter with the blacklist\_names option.
