通过Golang + eBPF实现无侵入应用可观测 张海彬 阿里云 应用可观测技术专家 目 录 eBPF简介 01 eBPF在云原生场景下的应用 02 微服务可观测的挑战 03 Golang + eBPF实现数据采集 04 构建完整的应用可观测系统 05 eBPF简介 第一部分 eBPF简介 01. eBPF简介 eBPF = extended Berkeley Packet 夯机宕机，资源异 常… 应用组件异常：线程池满，数据库连接无法获取， OOM，文件读取错误… 无法自顶向下端到端 串联导致棘手问题频 发。 Kubernetes下的可观测 Golang + eBPF实现数据采 集 第四部分 eBPF在可观测领域的优势 无侵入 多语言/多协议/多框架 全栈覆盖 无侵入性 • 无需修改代码 • 无需重启应用 • Verifier保证运行安全 程序跟其他的用户空间的程序没有太大区别  编译成二进制文件，可以适应不同运行环境  libbpf 扮演bpf程序装载机角色  开发人员只需要关注bpf程序的正确性和性能，不 需要关注其他依赖关系 通过Golang加载eBPF程序 01. 副标题 func loadSync() error { // Allow the current process to lock memory for eBPF

更多Golang资料包：扫码进入Github 1. 算术运算符 算数运算符就是对数值类型的变量进行运算的，比如，加减乘除。在Go中运用非常的多 算数运算符 除法演示 //说明，如果运算的数都是整数，那么除后，将会去除小数位 fmt.Println(10 / 4) //2 var n1 float32 = 10 / 4 fmt.Println(n1) //2 //如果我们希望保留小数，那么就需要有浮点数参与运算 这样我们可以看到取模的一个本质运算 3. Golang 的自增只能当做一个独立的语言使用时，不能这样使用 b := a++ 或者 b := a-- 错误用法 4. Golang 的 ++ 和 -- 只能写在变量的后面，不能写在变量的前面，即，只有 a++, a-- 没有 ++a, --A 错误演示 5. Golang 的设计者去掉了 c/java 中自增和自减的容易混淆的写法，让golang 更加简介，统一（强制性） 变量 字符串 符号 分隔符 Go 语言一行代表一个语句的结束，不像 C 家族语言一样以分号结束 如果一个语句写多行就需要加一个分号，不推荐 字符串连接 Go 语言字符串连接通过 `+` 实现 案例 ： fmt.Println("Google " + "Runoob") 关键字 关键字或保留字 预定义标识符 Go 语言的空格 1. 变量声明必须用空格隔开。例如: var age
