Not eligible for data streams because config contains one or more settings that are not compatible with data streams: {"index"=>"logstash-%{+YYYY.MM.dd}"}

Hi, I am working on the ELK stack using Docker compose. I am following this tutorial: Getting started with the Elastic Stack and Docker-Compose | Elastic Blog. Everything works except Logstash. When I run docker-compose I get this error: [logstash.outputs.elasticsearch][main] Not eligible for data streams because config contains one or more settings that are not compatible with data streams: {"index"=>"logstash-%{+YYYY.MM.dd}"}.

This is my logstash.conf file; it is almost the same as in the tutorial above.

input {
 file {
   #https://www.elastic.co/guide/en/logstash/current/plugins-inputs-file.html
   #default is TAIL which assumes more data will come into the file.
   #change to mode => "read" if the file is a compelte file.  by default, the file will be removed once reading is complete -- backup your files if you need>   mode => "tail"
   path => "/var/log/docker/docker-valheim.log"
 }
}

filter {
}

output {
 elasticsearch {
   index => "logstash-%{+YYYY.MM.dd}"
   hosts=> "${ELASTIC_HOSTS}"
   user=> "${ELASTIC_USER}"
   password=> "${ELASTIC_PASSWORD}"
   cacert=> "certs/ca/ca.crt"
 }
}

This is my logstash service in docker-compose.yml file

...
logstash01:
    depends_on:
      es01:
        condition: service_healthy
      kibana:
        condition: service_healthy
    image: docker.elastic.co/logstash/logstash:${STACK_VERSION}
    container_name: logstash

      - ELASTIC_USER=elastic
      - ELASTIC_PASSWORD=${ELASTIC_PASSWORD}

I also tried using something like this but still get the same error ...

 index => "logstash"

Hi @Dinoo Welcome to the community!

What version of the stack?

Dinoo · September 25, 2023, 9:42pm

Hi @stephenb, thank you for the warm welcome. My stack version is 8.7.1.

STACK_VERSION=8.7.1.

Logstash 8 per default will try to write on data streams, since you have the index option in the output to write to normal indices you need to disable it.

Add the option data_stream => false to your elasticsearch output and it should work.

Hi @leandrojmp, Thank you for your quick response. I've added data_stream => false to my logstash.conf file, and the error disappeared. But when I try to create a data view and type logstash* in the "Index pattern" field, I get the following message:

Here are the logs:

Go to Stack Management > Index Management and see if you indeed have an index starting with logstash in the name.

Also, is the file /var/log/docker/docker-valheim.log still being written or it is already complete?

Dinoo · September 25, 2023, 11:29pm

Under Stack Management > Index Management, I don't see index starting with logstash in the name.

File /var/log/docker/docker-valheim.log is still being written.

Dinoo · September 26, 2023, 7:13pm

Hi guys, Just to let you know, I figured out why I wasn't seeing the logstash index. I accidentally mistyped the path to my log file in the logstash.conf file. After a simple change, everything works fine. Thank you for your help, guys.
