由于配置错误无法启动 logstash

Question

所以我正在设置 ELK，我成功安装了 elastic 和 kibana，但在启动 logsearch 时出错，这是错误

据我所知，这是 logstash 配置问题，但我不知道错误在哪里（虽然错误确实告诉我它在第 13 行，但我不知道出了什么问题），我是 ELK 的新手，请告诉我如何修复它这是 logstash 配置

# Sample Logstash configuration for creating a simple
# Beats -> Logstash -> Elasticsearch pipeline.

input {
    file{
        type => "syslog"
        path => "D:/new_logging/log/application.log"
    }
}

output {
    stdout{ codec => rubydebug }
    elasticsearch => {
        hosts => ["localhost:9200"]
        index => "testing"
    }
}

您的问题正好在第 13 行：elasticsearch => {，请删除 => (https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html)

# Sample Logstash configuration for creating a simple
# Beats -> Logstash -> Elasticsearch pipeline.

input {
    file{
        type => "syslog"
        path => "D:/new_logging/log/application.log"
    }
}

output {
    stdout { codec => rubydebug }
    elasticsearch {
        hosts => ["localhost:9200"]
        index => "testing"
    }
}

由于配置错误无法启动 logstash
