+title: "[视频] 云原生学院 - 后分布式追踪时代的性能问题定位——方法级性能剖析"
+date: 2020-08-13
+author: 吴晟
+description: "由云原生社区主办的线上直播分享。"
+---
+
+## 吴晟
+
+吴晟,Apache 基金会会员,Apache SkyWalking 创始人、项目 VP 和 PMC 成员,Apache 孵化器 PMC 成员,Apache ShardingSphere PMC成员,Apache APISIX PMC 成员,Apache ECharts (incubating) 和Apache DolphinScheduler (incubating) 孵化器导师,Zipkin 成员和贡献者。
+
+## 分享大纲
+
+1. 分布式追踪兴起的背景
+2. SkyWalking和其他分布式追踪的异同
+3. 定位问题的流程和方法
+4. 性能剖析的由来、用途和优势
+
+## 听众收获
+
+听众能够全面的了解分布式追踪的技术背景,和技术原理。以及为什么这些年,分布式追踪和基于分布式追踪的APM系统,Apache SkyWalking,得到了广泛的使用、集成,甚至云厂商的支持。同时,除了针对追踪数据,我们应该关注更多的是,如何利用其产生的监控数据,定位系统的性能问题。以及它有哪些短板,应该如何弥补。

+### 活动现场
+
+2020年11月14日Apache SkyWalking 2020 DevCon由贝壳找房和tetrate赞助,Apache SkyWalking、云原生、Apache APISIX、Apache Pulsar 和 ALC Beijing 五大社区合作,在贝壳找房一年级会议室盛大举行,本次活动主要面对Apache SkyWalking的使用者、开发者和潜在用户。线上线下共有230多人报名。经统计,实际参加活动人数超过130人,近60%的人愿意抽出自己的休息时间,来交流学习Apache SkyWalking和开源文化。不难看见,在可预见的未来,中国的开源项目很快将进入下一个维度,那必定是更广的社区人员参与,更高技术知识体现,更强的线上稳定性和及时修复能力。
