* Use correct copyright years.
Also include the start year.
* Improve copyright notices.
Use the proper start year instead of just 2018.
Add the right owner Draios dba Sysdig.
Add copyright notices to some files that were missing them.
Replace references to GNU Public License to Apache license in:
- COPYING file
- README
- all source code below falco
- rules files
- rules and code below test directory
- code below falco directory
- entrypoint for docker containers (but not the Dockerfiles)
I didn't generally add copyright notices to all the examples files, as
they aren't core falco. If they did refer to the gpl I changed them to
apache.
New argument --metric, which can be cpu|drops, controls whether to graph
cpu usage or event drop percentage. Titles/axis labels/etc. change
appropriately.
Add shell scripts to make it easier to collect performance results from
traces, live tests, and phoronix tests.
With run_performance_tests.sh you specify the following:
- a subject program to run, using --root
- a name to give to this set of results, using --variant
- a test to run, using --test
- a file to write the results to, using --results.
For tests that start with "trace", the script runs falco/sysdig on the
trace file and measures the time taken to read the file. For other
tests, he script handles starting falco/sysdig, starting a cpu
measurement script (a wrapper around top, just to provide identical
values to what you would see using top) to measure the cpu usage of
falco/sysdig, and running a live test.
The measurement interval for cpu usage depends on the test being run--10
seconds for most tests, 2 seconds for shorter tests.
The output is written as json to the file specified in --results.
Also add R scripts to easily display the results from the shell
script. plot-live.r shows a linechart of the cpu usage for the provided
variants over time. plot-traces.r shows grouped barcharts showing
user/system/total time taken for the provided variants and traces.
One bug--you have to make the results file actual json by adding
leading/trailing []s.
