USE-Report

Linux & OS X Build Status MIT licensed

usereport gathers system performance statistics on the local host that may be used as the base information for a performance analysis following the USE methodology created by Brendan Gregg. Please see this blog post by Brendan for an introduction to USE and the statistics gathered by this tool. The usereport tool is part of my base server installation. I use it everywhere. It allows me to quickly assess several system characteristics in case of performance issues.

usereport comes with bundled configuration files for Linux and macOS, respectively, that are built into the corresponding binary. The configuration files contain a pre-defined selection of performance measurement and analysis tools. Please see the contrib directory for these configuration tools. In case of Linux, several profiles allow for statistics gathering depending on the context of your analysis, i.e., mem for virtual memory and net for network issues. With usereport you do not need to remember the exact tools and their parameters to conduct a performance analysis. Furthermore, each tool configuration contains descriptions of the output to ease interpretation of results, e.g., meaning and metrics of the gathered values, as well as links to further information.

The output format of usereport is usually Markdown or HTML for convenient reading. JSON output is also available for automatic processing, or you can define your own output format using Handlebars templates. The following screenshots present parts of the HTML output created by usereport running the net profile performance analysis on Linux -- see the full report here.

The main functionality is exposed as a Rust library to be used in your own projects at your convenience.
