Hello,  
I have a data taken from the filter elasticsearch query.

> elasticsearch {  
> hosts =\> ["localhost:9200"]  
> index =\> "elasticinput"  
> query =\> '\_id=%{fingerprint}'  
> fields =\> { "request\_ip\_count" =\> "new\_request\_ip\_count" }  
> fields =\> { "request\_counter\_attempts" =\> "new\_request\_counter\_attempts" }  
> fields =\> { "request\_domain\_root" =\> "new\_request\_domain\_root" }  
> }

The fields contains a number:  
"request\_ip\_count":"3"

How can I increment this field by 1?  
I want it to be: "request\_ip\_count":"4"

Is there a way?

How about

```
    ruby {
        code => '
            c = event.get("request_ip_count")
            if c
                event.set("request_ip_count", c.to_i + 1)
            end
        '
    }
```

Hey Badger,  
my solution last week that I forgot to publish was:

if [request\_ip\_count] != "" {  
ruby {  
code =\> '  
event.set("request\_ip\_count", event.get("request\_ip\_count").to\_i + 1)  
'  
}  
}
