Mark Stemm b76423b31d Useful scripts to collect/display perf results.
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.

Sysdig Falco

####Latest release

v0.2.0 Read the change log

Dev Branch: Build Status
Master Branch: Build Status

Overview

Sysdig Falco is a behavioral activity monitor designed to detect anomalous activity in your applications. Powered by sysdigs system call capture infrastructure, falco lets you continuously monitor and detect container, application, host, and network activity... all in one place, from one source of data, with one set of rules.

What kind of behaviors can Falco detect?

Falco can detect and alert on any behavior that involves making Linux system calls. Thanks to Sysdig's core decoding and state tracking functionality, falco alerts can be triggered by the use of specific system calls, their arguments, and by properties of the calling process. For example, you can easily detect things like:

  • A shell is run inside a container
  • A server process spawns a child process of an unexpected type
  • Unexpected read of a sensitive file (like /etc/shadow)
  • A non-device file is written to /dev
  • A standard system binary (like ls) makes an outbound network connection

This is the initial falco release. Note that much of falco's code comes from sysdig, so overall stability is very good for an early release. On the other hand performance is still a work in progress. On busy hosts and/or with large rule sets, you may see the current version of falco using high CPU. Expect big improvements in coming releases.

Contributor License Agreements

###Background As we did for sysdig, we are formalizing the way that we accept contributions of code from the contributing community. We must now ask that contributions to falco be provided subject to the terms and conditions of a Contributor License Agreement (CLA). The CLA comes in two forms, applicable to contributions by individuals, or by legal entities such as corporations and their employees. We recognize that entering into a CLA with us involves real consideration on your part, and weve tried to make this process as clear and simple as possible.

Weve modeled our CLA off of industry standards, such as the CLA used by Kubernetes. Note that this agreement is not a transfer of copyright ownership, this simply is a license agreement for contributions, intended to clarify the intellectual property license granted with contributions from any person or entity. It is for your protection as a contributor as well as the protection of falco; it does not change your rights to use your own contributions for any other purpose.

For some background on why contributor license agreements are necessary, you can read FAQs from many other open source projects:

As always, we are grateful for your past and present contributions to falco.
