wildfly 23.0.1 wildfly with jaegertracing exception

Question

我在Centos 8下的Wildfly 23.0.1 Centos (openjdk 11)上运行。

我根本没有在我的应用程序中使用opentrace，我也没有添加任何jaeger依赖。每当我查看日志时，我经常得到如下所示的异常(级别: Warn)：

这些消息填满了日志文件，我不知道如何禁用不想要的opentrace功能。我在谷歌上找不到关于这个奇怪的例外的东西。有没有人知道些什么？

诚挚的问候

Answer 1

如果您不使用它，您可以在CLI中执行类似以下操作：

/subsystem=microprofile-opentracing-smallrye/jaeger-tracer=jaeger:write-attribute(name=sampler-param, value=0)

另一种解决方案是删除开放竞赛子系统，安装ajeger，或者等待修复了https://issues.redhat.com/browse/WFLY-14625的WildFly发布

Answer 2

您可以通过删除来禁用此功能

<subsystem xmlns="urn:wildfly:microprofile-opentracing-smallrye:3.0" default-tracer="jaeger">
    <jaeger-tracer name="jaeger">
        <sampler-configuration sampler-type="const" sampler-param="1.0"/>
    </jaeger-tracer>
</subsystem>

在standalone.xml中

Answer 3

在执行wildfly的同时，执行jaeger应用程序-一个日志跟踪器，使用适当的端口配置。您可能会找到要运行的docker映像。
