If clause seems not to be working

Elastic Stack Logstash

Hi guys.
I'm just wanting to log different event to different indexes and I'm trying to achieve it by using tags.

input {
  udp {
    port => 25826
    type => "collectd"
    buffer_size => 1452
    codec => collectd { }
  }
}


input {
    udp {
      port => 5514
      codec => "json"
      type => "sensu"
      tags => "sensu"
  }
}

Output Filter:

output {
  if [@metadata][beat] {
    elasticsearch {
      hosts => ["server"]
      sniffing => true
      manage_template => false
      index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
      document_type => "%{[@metadata][type]}"
    }
  } else {
    elasticsearch {
      hosts => ["server"]
      sniffing => true
      manage_template => false
      index => "collectd-%{+YYYY.MM.dd}"
      document_type => "collectd"
    }
  }
}

Separate filter for sensu:

output {
   if "sensu" in [tags] {
elasticsearch {
  hosts => ["server"]
  sniffing => true
  manage_template => false
  index => "sensu-%{+YYYY.MM.dd}"
  document_type => "sensu"
  }
 }
}

When I restart the service I cannot see the data anymore in sensu index, if I remove the if clouse if works , what' wrong, I've already define the tag sensu in the input filter, doesn't it work that way?

What am I doing wrong?
Thanks in advance

Can you try inserting as an output stdout { codec => rubydebug }.? That will show you the full event data and let us see if the sensu tag is being deleted somehow. Could a filter be mangling it somewhere?

Hi Andrew,
Yeah, there was a filter that was the culprit, now I'm able to send the data to separate indexes including sensu

I left the beat output like this:

output {
  if [@metadata][beat] {
    elasticsearch {
      hosts => ["server"]
      sniffing => true
      manage_template => false
      index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
      document_type => "%{[@metadata][type]}"
    }
  }
}

Created a new one for collectd:

output {
    if "collectd" in [tags] {
    elasticsearch {
      hosts => ["server"]
      sniffing => true
      manage_template => false
      index => "collectd-%{+YYYY.MM.dd}"
      document_type => "collectd"
    }
  }
}

And this one for sensu:

output {
    stdout { codec => rubydebug }
    if "sensu" in [tags] {
    elasticsearch {
      hosts => ["server"]
      sniffing => true
      manage_template => false
      index => "sensu-%{+YYYY.MM.dd}"
      document_type => "sensu"
     }
    }
  }

Now I can see in the logs:

 "last_ok" => 1479846616,
                 "silenced" => false,
              "silenced_by" => [],
                 "@version" => "1",
               "@timestamp" => "2016-11-22T20:30:16.382Z",
                     "tags" => [
        [0] "sensu"
    ],
                     "host" => "x.x.x.x"
}

Thank you very much for your time and support
Regards
