红帽全球峰会第 21 章 使用 BPF Compiler Collection 分析系统性能
BPF Compiler Collection (BCC)通过组合 Berkeley Packet Filter (BPF)的功能来分析系统性能。使用 BPF，您可以安全地运行内核中的自定义程序，以访问系统事件和数据，以性能监控、追踪和调试。BCC 简化了 BPF 程序的开发和部署，用户可使用工具和库从其系统中提取重要见解。
21.1. 安装 bcc-tools 软件包
安装 bcc-tools 软件包以获取 BPF Compiler Collection (BCC)库和相关工具。
流程
安装 bcc-tools。
dnf install bcc-tools
# dnf install bcc-toolsCopy to Clipboard Copied! BCC 工具安装在
/usr/share/bcc/tools/目录中。
验证
检查安装的工具。
ls -l /usr/share/bcc/tools/
# ls -l /usr/share/bcc/tools/Copy to Clipboard Copied! 此时会显示安装的工具列表。列表中的
doc目录为每个工具提供了文档。
