System Capabilities Reporter

Sysreport is a system capability reporting tool that gives application developers a quick summary of how the system is configured and what performance features are available, on the Linux system the tool is running on.

This tool is aimed at anyone trying to profile performance on Arm-based systems; this includes cloud instances, bare metal servers, and small devices such as developer boards and Raspberry Pi devices.

The tool is invoked on the command-line and takes about a second to run. It displays a single page of output in text format.

Sysreport is not a benchmarking tool and does not modify the system in any way. It is also not intended to report current system status, only system configuration.

This tool aims to:

  • Report system configuration in a way that is focused on performance analysis, list which performance tools and features are available
  • Give useful advice on what you might do to improve your configuration for performance analysis
  • Run on any system (bare metal vs VM vs container, different operating systems and kernels, root vs non-root access, etc.)
  • Save the user from having to read multiple pages of documentation to understand what individual commands to run to gather everything they need

Example use cases:

  • As a developer, I want to know if my cloud instance supports a particular performance feature I require, so that I am able to debug a performance problem
  • As a developer, I want a quick single page summary of my system's performance configuration, so that I don't have to run lots of different commands manually
  • As a developer, I would like to know suggested configuration changes I can make to my system, so that I can improve my ability to collect performance information

Usage

Clone this git repository (or copy the repository contents) onto the target system for evaluation:

git clone https://github.com/ArmDeveloperEcosystem/sysreport.git

Now change into the src directory:

cd sysreport/src

To print usage help:

python sysreport.py --help

Example usage:

  • System overview with increased verbosity: 
    python sysreport.py --verbose
  • Check which kernel configuration options were set at build time: 
    python sysreport.py --config
  • System overview with additional information about which security vulnerabilities the system is exposed to: 
    python sysreport.py --vulnerabilities
