I have one field  
index = in  
type = mytype  
field =  
...  
...  
count  
...  
...

i just want to write a script which will update my count field by 1 in ES leaving rest as it was from logstash,

so my logstash \*.conf file looks like  
so input to logstash is

id=ET12 (script should increment count field in elasticsearch by one of this id)

```
  input { 
	http {
    ...
  }
}

output { 
  stdout { codec => json }
}

```

what should go inside output of logstash to achieve what i want?  
kindly help  
thanks
