Jenkins Logstash插件不向Logstash发送数据

Question

我想使用插件将Jenkins日志发送到Logstash。

我就是这样在Jenkins中配置Logstash插件的：

jenkins-logstash-plugin配置1：https://i.stack.imgur.com/EsIgY.png

我假设在logstash.conf中，我必须在输入部分使用HTTP：

input {
  http {
    host => "127.0.0.1"
    port => 31311
  }
}

但是在Jenkins构建日志中，我可以看到错误：

> [logstash-plugin]: Failed to send log data to
> ELASTICSEARCH:http://host_name:31311. [logstash-plugin]: No Further
> logs will be sent to http://host_name:31311.
> org.apache.http.conn.HttpHostConnectException: Connect to
> host_name:31311 [/host_name] failed: Connection refused (Connection
> refused)  at
> org.apache.http.impl.conn.DefaultHttpClientConnectionOperator.connect(DefaultHttpClientConnectionOperator.java:151)
>   at
> org.apache.http.impl.conn.PoolingHttpClientConnectionManager.connect(PoolingHttpClientConnectionManager.java:353)
> ... 
> Caused by: java.net.ConnectException: Connection refused
> (Connection refused)  at java.net.PlainSocketImpl.socketConnect(Native
> Method)   at
> java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350)

当我将Jenkins配置中的端口号更改为Elasticsearch端口9200而不是31311时，错误就消失了。但在这种情况下，数据直接写入Elasticsearch。

如何让Jenkins将构建日志发送到Logstash？

更新：我现在能够在Logstash中发送和获取日志，一切正常。但是在Jenkins控制台中，我可以看到向Logstash发送日志时的错误，这可以接受吗？

Answer 1

正如OP提到的，第一个问题是凭据问题(用户名、密码、密钥)。

第二个错误消息("No Further logs will be sent to... ")是在这里看到的，它意味着：

• url必须在JENKINS Logstash插件中定义，
• 您可以自己尝试编译(并手动安装.hpi文件)插件，因为有关该异常的错误在两天前刚刚修复：PR 22；参见提交5078。
