使用ktrace可以跟踪一个进程的行为。要跟踪一个进程,需要使用-p选项指定要跟踪的进程ID,使用-w选项将跟踪结果写入文件中。例如,要跟踪进程ID为1234的进程并将其结果写入文件trace.out,可以使用以下命令: ktrace-p1234-wtrace.out 3.停止ktrace 当您完成跟踪并得到所需结果时,可以使用Ctrl+C停止ktrace。它会将结果写...
引言 Linux 内核的调试是一项复杂的任务,涉及深入理解内核源码、使用专门的调试工具,以及掌握动态探测与跟踪技术(如 Kprobe 和 Ktrace)。此外,内核崩溃的分析与处理对于内核开发人员和运维工程师来说至关重要。本文将介绍常见的内核调试工具、Kprobe 和 Ktrace 的应用,以及内核崩溃的分析方法,并通过代码实验来加深理解。
ktrace— process tracing LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <sys/param.h> #include <sys/time.h> #include <sys/uio.h> #include <sys/ktrace.h> int ktrace(const char *tracefile,int ops,int trpoints,int pid); ...
ktrace [options] command Trace kernel operations for process command and log data to file ktrace.out in the current working directory. The tracing will continue until you either exit command or clear the trace points (with the -c or -C options). Use kdump to view the trace log. ...
NetBSD-1.0的ktrace 运行ktrace命令的时候报错了: google搜索后说是要在增加“options KTRACE”选项到内核中。嗯,试试看: 增加“options KTRACE”选项到TOR_NetBSD文件中: 重新编译内核: 编译结果: 用新编译的内核替换旧内核,并重启系统: OK,ktrace命令正常执行了。
kern.ktrace.request_pool bounds the number of trace events being logged at a time. Sysctl tunables that control process debuggability (as determined by p_candebug(9)) also affect the operation of ktrace(). RETURN VALUES The ktrace() function returns the value 0 if successful; otherwise ...
