性能工具之所以使用扩展的BPF,部分原因在于它的可编程性。BPF程序可以执行自定义等待时间计算和统计摘要。仅这些功能就可以构成一个有趣的工具,并且还有许多其他具有这些功能的跟踪工具。使BPF与众不同的是,它还高效且生产安全,并且内置于Linux内核中。使用BPF,您可以在生产环境中运行这些工具,而无需添加任何新的内核组...
该工具通过检测 sched:sched_process_exit 跟踪点及其参数来工作,并且还使用bpf_get_current_task(),以便可以从任务结构中读取开始时间(不稳定的接口详细信息)。由于此跟踪点很少触发,因此该工具的开销可以忽略不计。 本人的实战截图: runqlat runqlat是一个BCC和bpftrace工具,用于测量CPU调度程序延迟,通常称为运行...
