USE Method: Linux Performance Checklist
The USE Method provides a strategy for performing a complete check of system health, identifying common bottlenecks and errors. For each system resource, metrics for utilization, saturation and errors are identified and checked. Any issues discovered are then investigated using further strategies. This is an example USE-based metric list for Linux operating systems (eg, Ubuntu, CentOS, Fedora). Th
