Hi,

I am trying to convert few of my fields to integer using logstash 1.5. When converting just one field it works fine doing this to convert my field "failed" to integer:

```
   mutate {
               convert => ["failed", "integer"]
         }

```

But I have read in the documentation that it's possible to use an array of fields to convert multiple fields to integer. I have tried in many different combinations and I cannot manage to convert many fields providing an array of fields. I have tried this syntax and also different variations without luck

```
mutate {
     convert => {
            ["failed", "exit_status"] => "integer",
          }
        }

mutate {
               convert => ["exit_status", "failed"], "integer"
         }

   mutate {
               convert => ["exit_status", "failed"] => "integer"
         }

```

could anyone provide a working example to convert an array of fields using logstash-1.5? Right now the only workaround I found is to define a new convert entry by field to convert...

I found the working syntax thanks to @qchris in the #logstash irc channel:

```
mutate {
         convert => {
                  "failed" => "integer"
                  "exit_status" => "integer"
         }
}
```
