使用启动脚本通过命令行界面将Zipkin跟踪添加到WildFly

Question

我正尝试在Wildfly服务器上添加跟踪功能(特别是Keycloak Docker镜像)

遵循本文档https://docs.wildfly.org/19/Admin

我走了这么远

/extension=org.wildfly.extension.microprofile.opentracing-smallrye:add
/subsystem=microprofile-opentracing-smallrye:add

但我无法让下一部分工作来将其设置为指向zipkin:9411

指令中的下一个命令失败

[standalone@localhost:9990 /]  /subsystem=microprofile-opentracing-smallrye/jaeger-tracer=my-tracer:add()
{
    "outcome" => "failed",
    "failure-description" => "WFLYCTL0030: No resource definition is registered for address [
    (\"subsystem\" => \"microprofile-opentracing-smallrye\"),
    (\"jaeger-tracer\" => \"my-tracer\")
]",
    "rolled-back" => true
}

但是，使用/opt/jboss/startup-scripts/也会失败

Executing cli script: /opt/jboss/startup-scripts/enable-tracing.cli
No connection to the controller.

使用@ehsavoie回答，我得到了更多

embed-server --admin-only=true
/extension=org.wildfly.extension.microprofile.opentracing-smallrye:add()
/subsystem=microprofile-opentracing-smallrye:add()
/subsystem=microprofile-opentracing-smallrye/jaeger-tracer=my-tracer:add()
/subsystem=microprofile-opentracing-smallrye/jaeger-tracer=my-tracer:write-attribute(name=sender-endpoint,value=http://tracing:9411)
/subsystem=microprofile-opentracing-smallrye/jaeger-tracer=my-tracer:write-attribute(name=propagation,value=[B3])
/subsystem=microprofile-opentracing-smallrye/jaeger-tracer=my-tracer:write-attribute(name=reporter-log-spans,value=true)
/subsystem=microprofile-opentracing-smallrye:write-attribute(name=default-tracer,value=my-tracer)
stop-embedded-server

但是仍然没有登录到使用B3的zipkin。

我也试过

/subsystem=microprofile-opentracing-smallrye/jaeger-tracer=my-tracer:write-attribute(name=sender-endpoint,value=http://tracing:9411/api/v1/spans)

Answer 1

embed-server --admin-only=true
/extension=org.wildfly.extension.microprofile.opentracing-smallrye:add()
/subsystem=microprofile-opentracing-smallrye:add()
/subsystem=microprofile-opentracing-smallrye/jaeger-tracer=my-tracer:add()
stop-embedded-server

这个jboss-cli脚本应该在正确启动服务器之前启用opentracing。我不确定如何/何时可以使用keycloack图像执行该操作

添加子系统后需要重新加载：

[standalone@localhost:9990 /] /extension=org.wildfly.extension.microprofile.opentracing-smallrye:add
{"outcome" => "success"}

[standalone@localhost:9990 /] /subsystem=microprofile-opentracing-smallrye:add
{
    "outcome" => "success",
    "response-headers" => {
        "operation-requires-reload" => true,
        "process-state" => "reload-required"
    }
}

[standalone@localhost:9990 /] reload
[standalone@localhost:9990 /] /subsystem=microprofile-opentracing-smallrye/jaeger-tracer=my-tracer:add()
{"outcome" => "success"}

Answer 3

我推荐使用https://github.com/open-telemetry/opentelemetry-java-instrumentation进行跟踪。需要以javaagent启动，这样JAVA_OPTS_APPEND才能与Keycloak Docker官方镜像配合使用，例如：

JAVA_OPTS_APPEND: "-javaagent:/opentelemetry-javaagent-all.jar"

然后是agent can be configured via env variables，例如：

OTEL_SERVICE_NAME: keycloak
OTEL_TRACES_EXPORTER: jaeger
OTEL_EXPORTER_JAEGER_ENDPOINT: <jaeger endpoint>

它也适用于未来的Keycloak X版本，没有复杂的启动脚本。
