Hey people,
I’m trying to get rid of this message which is flooding my CloudWatch. My setup is as follows:
```auto
...
ContainerDefinitions:
- Essential: true
Image: opensearchproject/logstash-oss-with-opensearch-output-plugin:7.16.2
Command:
- "-e"
- !Sub |
input {
tcp {
port => 9601
codec => json
}
udp {
port => 9602
codec => json
}
sqs {
queue => "${LogstashFallbackQueue.QueueName}"
id_field => "sqs_id"
polling_frequency => 20
region => "${AWS::Region}"
threads => 1
}
}
filter {
mutate {
remove_field => ["path", "host", "port"]
}
}
output {
opensearch {
index => "logstash-%{+YYYY.MM.dd}"
hosts => ["${OpensearchEndpoint}"]
auth_type => {
type => "aws_iam"
region => "${AWS::Region}"
}
}
}
Name: logstash
...
```
I have been trying to find information on what I need to change to get rid of this message, but most search results seem to be from Elasticsearch and not this specific plugin for Opensearch.

Hi @deleugpn,
What version of Logstash are you using? Logstash OSS 8.0 introduces a breaking change where all plugins run in ECS compatibility mode by default. If you use a compatible [OSS client](https://opensearch.org/docs/latest/clients/agents-and-ingestion-tools/index/#compatibility-matrices) you must override the default value to maintain legacy behavior:
`ecs_compatibility => disabled`
Please let us know if you still run into the issue once making the adjustment to your Logstash config.

I have the same warning message. I have logstash version 7.16.3.
I set the ecs\_compatibility = disabled on pipeline level, it helped to reduce some warnings but still, some warnings are there. I have tried to set ecs\_compatibility =\> disabled in pipelines as well. but no luck.
I have tried this as well, but no luck

Additionally, we see the following error, it seems it tries to look for 2x.json template and that does not exist. Do we need to install something special?
