spring-boot - LogBack - LogStash - 在 logback 中添加属性并将它们发送到 Logstash

Question

我在 SpringBoot 应用程序中使用 Logback 和 Logstash。

在 logback.xml 我有一个带有服务名称的属性，就像:

<configuration>

<include resource="org/springframework/boot/logging/logback/defaults.xml" />

<include resource="org/springframework/boot/logging/logback/console-appender.xml" />

<property name="spring.application.name" calue="service"/>

<appender name="stash" class="net.logstash.logback.appender.LogstashTcpSocketAppender">
    <destination>localhost:9600</destination>
    <encoder class="net.logstash.logback.encoder.LogstashEncoder"/>
</appender>

<root level="INFO">
    <appender-ref ref="CONSOLE" />
    <appender-ref ref="stash" />
</root>

</configuration>

Logstash conf 文件是这样的:

input{ tcp{
        port=> 9600
        host=>logstash
    }
}

filter {
grok {
match => {
  "message" =>
  "^%{TIMESTAMP_ISO8601:timestamp}\s+%{LOGLEVEL:level}\s+%{NUMBER:pid}\s+---\s+\[\s*%{USERNAME:thread}\s*\]\s+%{JAVAFILE:class}\s*:\s*%{DATA:themessage}(?:\n+(?<stacktrace>(?:.|\r|\n)+))?$"
}
}
date {
match => [ "timestamp" , "yyyy-MM-dd HH:mm:ss.SSS" ]
}
 mutate {
remove_field => ["@version"]
add_field => {
  "appid" => "%{[path]}"
}
add_field => {
  "levell" => "level"
}
add_field => {
  "mensage" => "message"
}
 }
   }
output{

 elasticsearch {
hosts => ["elasticsearch"]
index => "indice"
 }
   stdout{}
 } 

如何将 logback 文件中的应用程序名称属性添加为字段？

Answer 1

您可以为 LogstashEncoder 配置自定义字段，如下所示

<appender name="stash" class="net.logstash.logback.appender.LogstashTcpSocketAppender">
    <destination>192.168.99.100:4560</destination>

    <!-- encoder is required -->
    <encoder class="net.logstash.logback.encoder.LogstashEncoder">
      <customFields>{"appname":"${appName}"}</customFields>
    </encoder>
</appender>

例如，对于 spring boot 应用程序，您可以使用获取 spring 范围属性如下

<springProperty name="appName" source="spring.application.name"/>

或者从 .properties 文件中导入属性

<property  resource="application.properties" />
