logstash - 使用 Logstash 将数据从 Postgres 导出到 ElasticSearch 给出 LoadError: no such file to load -- pg

问题描述

我正在尝试使用 Logstash 将数据从 Postgres 导出到 ElasticSearch。

这是我的 conf 文件，位于路径“ /etc/logstash/conf.d ”

input {
    jdbc {
        jdbc_connection_string => "postgresql://localhost:5432/panzura"
        jdbc_user => "panzura"
    jdbc_password => "*******"
    jdbc_driver_library => "/etc/logstash/jdbc-drivers/postgresql-42.2.9.jar"
        jdbc_validate_connection => true
        jdbc_driver_class => "org.postgresql.Driver"
        statement => "SELECT * from file"
    }
}

filter { }


output {
    elasticsearch {
        index => "files"
        document_id => "%{id}"
        hosts => "https://vzfnrf9q3fagdht05b:xw32qdcnr4w2zgss@es.vizion.ai:443"
    }
}

现在，我正在尝试使用以下命令运行 logstash：

/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/pg-to-elastic.conf

但我收到以下错误：

如果我们专注于第一行，它会说：

Unable to connect to database. Tried 1 times {:error_message=>"LoadError: no such file to load -- pg"}

我无法解决这个问题。
