USE Practice Playground
by Adam Leskis
Practice Linux USE-method investigations against randomized host-level scenarios. Run `use-practice` to see what the options are, and put some load on the system to practice your USE methodology investigation skills. It already has the use-tool (https://github.com/lpmi-13/use-tool) installed, so you can begin with that, or just run a free-form investigation.

This playground features a ready-made random load generator that you can use to run through the various stages of Brendan Gregg's USE Methodolgy.
It analyzes the load across 4 different resources:
- cpu
- memory
- disk
- network
It's a bottom-up approach, exploring whether any of those resources are experiencing the following
- high Utilization
- Saturation
- Errors
and it can be done very quickly with existing linux tooling like:
- uptime
- free
- vmstat
- mpstat
- sar
- cat /proc/*
- iostat
...etc
