DTrace tools for debugging performance issues on SmartOS/SmartDataCenter cloud environments.
brendangregg/dtrace-cloud-tools is a collection of DTrace scripts written for debugging performance issues on SmartOS-based SmartDataCenter (SDC) clouds. It provides tools for operators and developers to analyze system behavior in these specific cloud environments. The scripts are unsupported but offer practical insights for troubleshooting.
Cloud operators and developers working with SmartOS/SmartDataCenter environments who need to diagnose performance problems using DTrace.
It offers specialized, version-specific DTrace tools tailored for SmartOS/SDC clouds, filling a niche gap in performance debugging for these platforms where mainstream tools may not apply.
Some DTrace tools written for the SmartOS/SmartDataCenter cloud (illumos-based)
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Specifically designed for SmartOS-based SmartDataCenter clouds, offering scripts that address unique performance issues in these environments, as highlighted by the focus on SDC versions and SmartMachines.
Includes tools tagged with suffixes like '_sdc5' and '_sdc6' for compatibility with different SDC versions, ensuring accurate debugging across kernel updates from OpenSolaris to illumos.
Developed from actual performance troubleshooting scenarios, providing practical, hands-on insights for cloud operators without unnecessary polish, as noted in the philosophy.
Separates scripts into smartmachine directories for containers and compute node tools for global zone execution, simplifying usage for different operator roles.
Explicitly marked as unsupported, meaning no official updates, bug fixes, or documentation, relying solely on community contributions or user effort.
Only functional on SmartOS/SDC environments based on illumos kernels, with no applicability to other operating systems like Linux or Windows, limiting its utility.
Requires deep knowledge of DTrace scripting and SmartOS architecture to effectively run and interpret scripts, making it inaccessible for novices or those new to these technologies.
