Here is my filebeats config  
processors:

- add\_tags:  
tags: [web, dev]  
target: "environment"

#=========================== Filebeat inputs =============================

filebeat.inputs:

- type: log

filebeat.config.modules:

# Glob pattern for configuration loading

path: ${path.config}/modules.d/\*.yml

reload.enabled: false

output.logstash:  
hosts: ["localhost:5044"]

Here is my logstash config

input {  
beats {  
port =\> "5044"  
}  
}  
filter {  
grok {  
match =\> { "message" =\> "%{COMBINEDAPACHELOG}"}  
}  
geoip {  
source =\> "clientip"  
}  
}  
output{

if "dev" in [tags] {  
amazon\_es {  
hosts =\> ["[https://mydevcluster](https://mydevcluster)"]  
region =\> "us-east-1"  
}  
}

if "mit" in [tags] {  
amazon\_es {  
hosts =\> ["[https://mymitcluster](https://mymitcluster)"]  
region =\> "us-east-1"  
}  
}  
}

I'm not seeing any data go into ES with this configuration. I've tested with

stdout { codec =\> rubydebug }, and I can see the tags going in and coming out.

I've tested going to individual clusters. They work independently.

I just get no data into the clusters when it's like this.

Thanks

As I read it, in your filebeat configuration your are adding a [field called environment](https://www.elastic.co/guide/en/beats/filebeat/master/add-tags.html). However, in your logstash configuration you are testing a field called tags.

add\_tag is used to add an array of values to a named field.

I changed it to simply this:

processors:

- add\_tags:  
tags: [dev]

Seems to work.
