Fix METADATA for perf_data_converter Test: NA Change-Id: I3b83c71c04826ea48263d9884e19e91289eb009a
The perf_to_profile
binary can be used to turn a perf.data file, which is generated by the linux profiler, perf, into a profile.proto file which can be visualized using the tool pprof.
For details on pprof, see https://github.com/google/pprof
THIS IS NOT AN OFFICIAL GOOGLE PRODUCT
To install all dependences and build the binary, run the following commands. These were tested on Debian GNU/Linux 8 (jessie):
sudo apt-get -y install autoconf automake g++ git libelf-dev libssl-dev libtool make pkg-config git clone --recursive https://github.com/google/perf_data_converter.git cd perf_data_converter/src make perf_to_profile
If you already have protocol buffers and googletest installed on your system, you can compile using your local packages with the following commands:
sudo apt-get -y install autoconf automake g++ git libelf-dev libssl-dev libtool make pkg-config git clone https://github.com/google/perf_data_converter.git cd perf_data_converter/src make perf_to_profile
Place the perf_to_profile
binary in a place accessible from your path (eg /usr/local/bin
).
There are a small number of tests that verify the basic functionality. To run these, after successful compilation, run:
make check clean make check clean -C quipper/ -f Makefile.external
Profile a command using perf, for example:
perf record /bin/ls
The example command will generate a profile named perf.data, you should convert this into a profile.proto then visualize it using pprof:
perf_to_profile perf.data profile.pb pprof -web profile.pb
Recent versions of pprof will automatically invoke perf_to_profile
:
pprof -web perf.data
We appreciate your help!
Note that perf data converter and quipper projects do not use GitHub pull requests, and that we use the issue tracker for bug reports.
