Hi,

I'd like to request some help with logstash, currently I'm trying to use it as a rsyslog gatherer, basically I've got this setup:

Devices Reporting to RSYSLOG  
RSYSLOG sending the logs to Logstash as JSON  
Logstash sending the data to ElasticSearch

It's working, but I noticed that by default it saved the data with the following index:

logstash-DATE

Where Date is the current day, I wanted to change this so all the logs from Rsyslog are saved using the index "syslog-infr-DATE" so I basically used this code to achieve it:

```
input {
  udp {
    host => "127.0.0.1"
    port => "10514"
    codec => "json"
    type => "rsyslog"
  }
}

output {
  if [type] == "rsyslog" {
    elasticsearch {
      hosts => ["172.16.0.4:9200"]
      index => "syslog-infr-%{+YYYY.MM.dd}"
    }
  }
}

```

It worked, it's saving it now with the index syslog-infr-DATE, but, at the same time it keeps saving the same records in parallel to the old index. So I basically have the same data in two indexes:

syslog-infr-DATE  
logstash-DATE

I don't know how to avoid this happening, my setup is basically using default values (in Logstash, Kibana and Elasticsearch) except for the IP addresses I changed (where to listen) and that configuration I just showed.

I'm using v5 of the ELK stack.

Thank you for any help in advance.

Please show your entire config, it will help diagnose the problem.

Also we’ve renamed ELK to the Elastic Stack, otherwise Beats and APM feel left out! 😉

Hi,

Thank you for the reply. I found out what was happening, I basically left some configuration that I was testing around and didn't notice, my bad.

And I'll sure remember not to call it the "ELK stack" again haha.

Thank you.
