## Question
now, i use shardingsphere-agent in sharding-proxy to record trace, the trace
plugin is zipkin, i want record traceid into log, but don not know how to bury
the code ， please see the steps：
* step 1 : add log support dependency
```java
@Override
public void start(final PluginConfiguration pluginConfig) {
if (!checkConfig(pluginConfig)) {
throw new PluginConfigurationException("zipkin config error,
host is null or port is %s", pluginConfig.getPort());
}
Properties props = pluginConfig.getProps();
String urlVersion =
Optional.ofNullable(props.getProperty("URL_VERSION")).orElse("/api/v2/spans");
String serviceName =
Optional.ofNullable(props.getProperty("SERVICE_NAME")).orElse("shardingsphere-agent");
String token =
Optional.ofNullable(props.getProperty("TOKEN")).orElse("");
sender = OkHttpSender.create(String.format("http://%s:%s%s%s";,
pluginConfig.getHost(), pluginConfig.getPort(), token != null && token.length()
> 0 ? "/" + token : token, urlVersion));
Sampler sampler = createSampler(pluginConfig);
zipkinSpanHandler = AsyncZipkinSpanHandler.create(sender);
tracing =
Tracing.newBuilder().localServiceName(serviceName).sampler(sampler).addSpanHandler(zipkinSpanHandler)
//add MDCScopeDecorator for add trace to MDC
.currentTraceContext(
ThreadLocalCurrentTraceContext.newBuilder()
.addScopeDecorator(MDCScopeDecorator.get())
.build()
)
.build();
}
```
* step 2：how to bury the code in agent plugin of zipkin ,have any suggest
????
if we want record trace , we must get the currentTraceContext from Tracing,
then execute code like this
```java
Scope scope = currentTraceContext.newScope(span.context());
try{
// ..... business code
}finally{
scope.close();
}
```
