ktap is a script-based dynamic tracing tool for Linux
|
|
|
|
|
|
|
|
|
|
It uses a scripting language and lets users trace the Linux kernel
|
|
|
|
|
dynamically. ktap is designed to give operational insights with
|
|
|
|
|
interoperability that allows users to tune, troubleshoot and extend
|
|
|
|
|
kernel and application. It's similar to Linux Systemtap and
|
|
|
|
|
Solaris Dtrace.
|
|
|
|
|
|
|
|
|
|
ktap doesn't support kernels older than 3.1.

To be able to resolve symbols in DSO and for sdt, you need to enable
|
|
|
|
|
elfutils.

Your kernel must have CONFIG_EVENT_TRACING,
|
|
|
|
|
CONFIG_PERF_EVENTS, and CONFIG_DEBUG_FS enabled to compile.

Buildroot automatically enables these in the kernel configuration.
