elasticsearch - How do I increment my count field of my document from logstash? -

i want update 1 field of document/log in elasticsearch logstash.

my logstash conf file

input {      http {     host => "127.0.0.1" # default: 0.0.0.0     port => 31311 # default: 8080   } }  output {    stdout { codec => json },   elasticsearch {         action => "update"         bind_host => "127.0.0.1"         bind_port => 9200         document_id => "et00009682"         index => "in12"         type => "event"   } } 

i want increment count field 1 how specify in output of logstash.

note: know update need use script

"script" : "ctx._source.count += 1" 

but not sure place in output of logstash?

kindly thanks

you can conf:

output {    stdout { codec => json },   elasticsearch {         action => "update"         bind_host => "127.0.0.1"         bind_port => 9200         document_id => "et00009682"         index => "in12"         type => "event"         doc_as_upsert => true         script => "ctx._source.count += 1"         script_lang => "groovy"         script_type => "inline"   } }
