systemtap (Linux trace/probe tool)
|
|
|
|
SystemTap provides free software (GPL) infrastructure to simplify the
|
|
gathering of information about the running Linux system. This assists
|
|
diagnosis of a performance or functional problem. SystemTap eliminates
|
|
the need for the developer to go through the tedious and disruptive
|
|
instrument, recompile, install, and reboot sequence that may be
|
|
otherwise required to collect data.
|
|
|
|
SystemTap provides a simple command line interface and scripting
|
|
language for writing instrumentation for a live running kernel plus
|
|
user-space applications. We are publishing samples, as well as
|
|
enlarging the internal "tapset" script library to aid reuse and
|
|
abstraction.
|
|
|
|
Among other tracing/probing tools, SystemTap is the tool of choice for
|
|
complex tasks that may require live analysis, programmable on-line
|
|
response, and whole-system symbolic access. SystemTap can also handle
|
|
simple tracing jobs.
