I have a "logstash" index with documents while I have hardcoded the name of the output index by the tags.

when I check in the index "logstash" my logs have the right tag "windows" or "iptable" ...  
I added a final "else" to be sure  
I have try with 7.12.0 and 7.12.1 with the same result ☹  
I don't find why I've got the logstash index.

my output.conf

> output {  
> if "iptable" in [tags] {  
> elasticsearch {  
> index =\> "firewall"  
> hosts =\> ["[http://elasticsearch:9200](http://elasticsearch:9200)"]  
> }  
> }  
> else if "winlogbeats" in [tags] {  
> elasticsearch {  
> index =\> "winlogbeats"  
> hosts =\> ["[http://elasticsearch:9200](http://elasticsearch:9200)"]  
> }  
> }  
> else if "windows" in [tags] {  
> elasticsearch {  
> index =\> "windows"   
> hosts =\> ["[http://elasticsearch:9200](http://elasticsearch:9200)"]  
> }  
> }  
> else {  
> elasticsearch {  
> index =\> "notag"   
> hosts =\> ["[http://elasticsearch:9200](http://elasticsearch:9200)"]  
> }  
> }  
> }

When [ILM](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-ilm) is enabled the index option on the output is ignored.

Hello,  
I have add `ilm_enabled => "false"` to all my output .  
Now I have my notag index ✌  
but after remove all index and a full restart ELK

> logstash |yellow|open|1|1|1965 |920.8kb  
> firewall|yellow|open|1|1 |6 |114kb  
> notag|yellow open |1 |1 | 1959| 882.9kb

The Logstash index seen to be a copy of all the other index...

Hello,  
find the solution in the log.  
there was in my pipeline a `output.conf.bak` before I try the index option.  
So I've got 2 output really stupid and simple .
