Usage: eu-stackprof [OPTION...] [--] [CMD]...
Collect systemwide stack-trace profiles.
Output options:
-f, --force Unlink output files to force writing as new.
-g, --gmon Generate gmon.BUILDID.out files for each binary.
-G, --hist-split=none/even/flex
Split gmon histogram output into even or flexible
chunks, default 'even'.
-n, --maxframes=MAXFRAMES Maximum number of frames to unwind, default 1 with
--gmon, 256 otherwise.
-o, --output=DIR Output directory for gmon.BUILDID.out files.
-p, --pid=PID Profile given PID, and its future children.
-v, --verbose Increase verbosity of logging messages
(modules/samples/frames/more).
-?, --help Give this help list
--usage Give a short usage message
-V, --version Print program version
Mandatory or optional arguments to long options are also mandatory or optional
for any corresponding short options.

Options (12)
| Option | Description | Source |
|---|
-f, --force | If the output directory for --gmon already contains files identified by the encountered build-ids, overwrite them with the newly collected data. | help + man |
-g, --gmon | Output program counter histograms and callgraphs for each executable binary encountered during profiling in gprof(1)'s gmon.out format. | help + man |
-G, --hist-split none/even/flex | Specify the method used to divide the address space into histograms for --gmon output. | help + man |
-n, --maxframes MAXFRAMES | Upper bound on the number of frames to unwind for each stack sample. | help + man |
-o, --output DIR | Directory where to write results when --gmon output is enabled. | help + man |
-p, --pid PID | Restrict the profile to process PID and its future children. | help + man |
-v, --verbose | Increase verbosity of logging messages (modules/samples/frames/more). | help + man |
-?, --help | Print a short list of options. | help + man |
--usage | Give a short usage message | help |
-V, --version | Print program version. | help + man |
-e, --event EVENT | Configure perf_events sampling according to the provided libpfm event specification (e.g. perf::CPU-CLOCK:freq=1000). (in the manual page but not in --help) | man |
--event-list | List available libpfm events and exit. (in the manual page but not in --help) | man |
Examples (4) from the manual page, untested
sudo eu-stackprof --gmon
Profile system-wide;sudo eu-stackprof -vv --gmon -o results/ -p 1211 --force
Profile PID 1211 and children forked from it;sudo eu-stackprof --gmon -o results/ --force -- vim test.txt
Likewise, launch vim and profile it:sudo eu-stackprof -vvv
Profile system-wide;
