Jenkins Logstash插件不会向Logstash发送数据

Question

I want to use Jenkins-Logstash plugin to send Jenkins logs to Logstash.

This is how I configured Logstash plugin in Jenkins:

[jenkins-logstash-plugin configuration][1] [1]: https://i.stack.imgur.com/EsIgY.png

I assume in logstash.conf I have to use HTTP plugin in input section:

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

But in Jenkins build logs I can see the error:

> [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)

And the error is gone when I change port number in Jenkins config to Elasticsearch port 9200 instead of 31311 . But in this case data is written directly to Elasticsearch.

How can I set Jenkins to send build logs to Logstash?

Update : I am able to send and get logs in Logstash now, everything works good. But in Jenkins console I can see the error when sending logs to Logstash, is it acceptable?

Answer 1

As mentioned by the OP, the first issue was a credential one (username, password, key)

The second error message (" No Further logs will be sent to... ") is seen here , and means that:

• the url has to be defined in the JENKINS Logstash Plugin ,
• you can try and compile (and manually installed the .hpi file) the plugin yourself, since a bug regarding that exception has just been fixed two days ago: PR 22 ; see commit 5078fcc .
