在日志中添加了 MDC,以便能够在 Stackdriver 仪表板和日志控制台中跟踪特定错误日志。当前的实现在本地机器上运行良好,但在云上却不是——只是不要将我的 MDC 包括在日志条目中。问题是我根本无法弄清楚可能是什么问题。

本地日志输出(包含“contextKey”:“someValue”):

{"traceId":"615b35dc7f639027","spanId":"615b35dc7f639027","spanExportable":"false","contextKey":"someValue","timestampSeconds":1552311117,"timestampNanos":665000000,"severity":"ERROR","thread":"reactor-http-nio-3","logger":"com.example.someservice.controller.MyController", ...}

同一服务的 Kubernetes 容器日志(此日志条目中没有“contextKey”:“someValue”):

{"traceId":"8d7287fa0ebdacfce9b88097e290ecbf","spanId":"96967afbe05dbf0e","spanExportable":"false","X-B3-ParentSpanId":"224dcb9869488858","parentId":"224dcb9869488858","timestampSeconds":1552312549,"timestampNanos":752000000,"severity":"ERROR","thread":"reactor-http-epoll-2","logger":"com.example.someservice.controller.MyController","message":"Something went wrong","context":"default","logging.googleapis.com/trace":"projects/my-project/traces/8d7287fa0ebdacfce9b88097e290ecbf","logging.googleapis.com/spanId":"96967afbe05dbf0e"}

我的 logback.xml:

<configuration>

    <appender name="CONSOLE_JSON" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
            <layout class="org.springframework.cloud.gcp.autoconfigure.logging.StackdriverJsonLayout">
                <projectId>${projectId}</projectId>
            </layout>
        </encoder>
    </appender>

    <springProfile name="local,dev,test">
        <root level="INFO">
            <appender-ref ref="CONSOLE_JSON"/>
        </root>
    </springProfile>
</configuration>

使用定义的 MDC 触发日志创建的控制器:

@RestController
@RequestMapping("v1/my-way")
@Slf4j
public class MyController {

    @GetMapping
    public void read() {
        MDC.put("contextKey", "someValue");
        log.error("Something went wrong");
        MDC.remove("contextKey")
    }

}

您的 MDC 字段应该在日志实体的“标签”节点上可用。你在那里查过吗?

同样在 Google Console 中的 Logs Viewer 中,可以将 MDC 字段设置为显示在日志记录中。对于该设置“labels.YouCustomMDCField:在查看选项 - >修改自定义字段(在屏幕的右上角)

更新:但是,您使用与我不同的方法登录到 Stackdriver。我在用着

<appender name="STACKDRIVER" class="com.google.cloud.logging.logback.LoggingAppender">
    <log>
        ${log_file_name}
    </log>
</appender>

这就是诀窍(我也有春天)。
