I'm following this tutorial to setup logstash for ballerina.
https://ballerina.io/learn/how-to-observe-ballerina-code/#elastic-stack
Created the logstash.conf with below content.
input {
beats {
port => 5044
}
}
filter {
grok {
match => { "message" => "%{TIMESTAMP_ISO8601:date}%{SPACE}%{WORD:logLevel}%{SPACE}[%{GREEDYDATA:package}]%{SPACE}-%{SPACE}%{GREEDYDATA:logMessage}"}
}
}
output {
elasticsearch {
hosts => "elasticsearch:9200"
index => "ballerina"
document_type => "ballerina_logs"
}
}
Started the docker with below command
docker run -h logstash --name logstash --link elasticsearch:elasticsearch -it --rm -v /tmp/pipeline:/usr/share/logstash/pipeline/ -p 5044:5044 docker.elastic.co/logstash/logstash:6.2.4
Getting this error on startup
