Performance tools for tracing and profiling the userspace stack in the platform
The pmtrace library provides the methods of tracing and profiling in other software components.
The pmtrace-daemon can manage a Lttng session and export the result in json format that can be loaded in Catapult tool. Catapult tool can then convert the json file to html and visualize it graphically on Chrome Browser.
The pmtrace-daemon-control manage the pmtrace-daemon.
Below are the tools and libraries (and their minimum versions) required to build
- cmake (version required by build environment)
- gcc 4.8.0
- make (any version)
- pkg-config 0.26
- libpbnjson
Once you have downloaded the source, enter the following to build it (after following commands):
$ mkdir BUILD
$ cd BUILD
$ cmake ..
$ make
$ sudo make install
To see a list of the make targets that cmake has generated, enter:
$ make help
From the directory where you originally ran make install, enter:
