tracing 板块是 Rust 程序的工具框架,用于收集结构和事件的诊断信息。在Tokio 这样的异步系统中,解释传统日志信息往往具有相当大的挑战性。由于单个任务在同一线程上多路复用,相关事件和日志行相互混合,因此很难跟踪逻辑流。与日志信息不同,tracing 中的Span有开始和结束时间,可由执行流进入和退出,并可存在于类似 ...

This PR changes the logging system in the Rust codebase to use the tracing and tracing-subscriber crates and configures them the same way as the Ruby extractor. In addition it adds the possibility to collect flame graph data by ssetting CODEQL_EXTRACTOR_RUST_OPTION_FLAME_LOG to a file path...

内核在packet filter和tracing等应用中提供了一系列的钩子来运行BPF代码。目前支持以下类型的BPF代码: static int __init register_kprobe_prog_ops(void){bpf_register_prog_type(&kprobe_tl);bpf_register_prog_type(&tracepoint_tl);bpf_register_prog_type(&perf_event_tl);return 0;}static int __init re...

本文节选自开源书籍<<Rust语言圣经>>,由RustCn荣誉推出 严格来说,tracing 并不是一个日志库,而是一个分布式跟踪的 SDK,用于采集监控数据的。 随着微服务的流行,现在一个产品有多个系统组成是非常常见的,这种情况下,一条用户请求可能会横跨几个甚至几十个服务。此时再用传统的日志方式去跟踪这条用户请求就变得较为...
