我在Centos 8下的Wildfly 23.0.1.Final(openjdk 11(上运行。
我在应用程序中根本没有使用opentrace，也没有添加任何jaeger依赖项。每当我查看日志时，我经常会得到一个excpetion(级别：Warn(，看起来如下：

这些消息填充了日志文件，我不知道如何禁用不需要的opentrace功能。我在谷歌上找不到关于这个奇怪的例外的东西。有人知道吗？
向致以最良好的问候
shane
如果不使用它，可以在CLI中执行以下操作：
/subsystem=microprofile-opentracing-smallrye/jaeger-tracer=jaeger:write-attribute(name=sampler-param, value=0)
另一个解决方案是删除opentraceing子系统，安装jaeger或等待WildFly的发布并修复https://issues.redhat.com/browse/WFLY-14625
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
与wildfly并行，执行jaeger应用程序-一个具有适当端口配置的日志跟踪器。您可能会找到要运行的docker映像。
