logstash echo怎么用

Logstash echo是一个Logstash插件，它可以在收到消息后简单地将消息发送回去。你可以使用以下配置示例：

input {
stdin {}
}

output {
stdout {}
# Echo back the input message
echo {}
}

当然，您可以根据需要调整配置。希望这可以回答您的问题。还有什么我可以帮忙的吗？

logstash安装教程

以下是在 Ubuntu 系统上安装 Logstash 的步骤：

1. 安装 Java：Logstash 是基于 Java 开发的，因此需要先安装 Java。在终端输入以下命令：

   sudo apt install openjdk-8-jdk

2. 导入 Logstash GPG 密钥：

   wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -

3. 添加 Logstash 软件包源：

   echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list

4. 更新软件包列表：

   sudo apt update

5. 安装 Logstash：

   sudo apt install logstash

6. 启动 Logstash：

   sudo systemctl start logstash

7. 验证 Logstash 是否在运行：

   sudo systemctl status logstash
