Linux
- https://0x.tools/ 0x.tools (GitHub) is a set of open-source utilities for analyzing application performance on Linux. It has a goal of deployment simplicity and minimal dependencies, to reduce friction of systematic troubleshooting. No need to install kernel modules or heavy monitoring frameworks. 0x.tools allow you to measure individual thread level activity, like executed code, sleep states, system calls and wait locations - by tracking (not tracing) and then sampling the right events at the right time.
