Linux Tracing Scripts
Author: [email protected]
This repository contains example scripts and tools for troubleshooting and performance analysis on Linux systems. It includes dynamic tracing scripts with FTrace, Perf, SystemTap, BPF/bcc.
| Directory | Short description |
|---|---|
| Ftrace | I/O latency histograms at microsecond resolution using ftrace |
| Perf | Linux Perf and uprobes for Oracle tracing and profiling |
| SystemTap_Linux_IO | SystemTap scripts for Linux I/O tracing and I/O latency measurements |
| SystemTap_Userspace_Oracle | SystemTap scripts for Oracle RDBMS troubleshooting and internals investigations using userspace dynamic tracing |
| BPF-bcc_Userspace_Oracle | BPF/bcc scripts for Oracle userspace tracing, mostly ports from previous SystemTap and Perf work |
Disclaimer: Many of the scripts provided here are experimental, may cause unwanted effect especially on busy production systems and overall may be incompatible with your current set-up and/or need some tweaking before running.
