Logstash tags conditional issue

[a.sailor (Andrea Marinaro)]

Hi all,
i'm trying to accomplish one very simple thing, but i'm now stuck.
This is my basic logstash pipeline:

input {
beats {
port => 5044
 }
 }

### FILTER SECTION ###

filter {

if "cms-access" in [tags] {
grok {
match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{DATA:app} %{GREEDYDATA:address} %{IP:ip} - - %{NUMBER:response} %{GREEDYDATA:request} %{QS:agent}" }
}
}
}


output {

if "cms-access" in [tags] {

        elasticsearch {
                    hosts => ["es_data1", "es_data2"]
                    index => "logstash-cms-access-%{+YYYY.MM.dd}"

         }
    }
}

But, obviously, nothing is ingested in Elasticsearch (i tried without if condition and it works).
Thanks

It works without the conditional? What does the tags field look like in elasticsearch when it works? (Or Kibana on the JSON tab.)

Hi Badger,

thanks for your reply.
Without conditional it works and it set tag according to filebeat.

I set the tag in Filebeat, so:

- type: log
  enabled: true
  tags: ["cms-access"]
  paths:
     - /logs/httpd/**/cms_com/access

What does the tags field look like in the JSON tab in Kibana when you remove the conditional?
