网络、操作系统、硬件 基础设施层复杂度日益增加 如何关联? 挑战3：数据散落，工具多， 缺少上下文，排查效率低下 业务应用 应用框架 容器虚拟化 系统调用 内核 应用性能监控（APM） Kubernetes监控 Kubernetes组件异常： Scheduler, KCM， etcd，api-server, coredns… 系统调用异常：网络请 求，内存申请，文件操 作，CGroup… 智能告警 eBPF + Golang 在阿里云应用可观测的实践 更标准 更稳定 无侵入 异常监控 持续剖析 what’s new： 应用监控eBPF版 • eBPF Agent性能提升20% • Otel Collector 性能提升80% • 无需要修改任何业务代码，一键接入eBPF监控 • 语言无关、框架无关、协议无关 无侵入的应用可观测 eBPF是一种在Linux内核运行的沙盒程序，无需修改 系统调用等Otel无法获取的数据指标。 新版控制台体验升级 • 提供多语言的无侵入的应用CPU热点查看 • 监控网络异常，如TCP Drop、TCP 重传 • 监控应用异常事件，如OOM 黄金三指标 调用链查询与分析 拓扑/上下游 网络大盘 容器监控 智能告警 持续剖析 接口监控 数据来源 Thank You, Every Gopher
