System Monitoring & Performance |
|
|
| Course Length - 4 Days | | | | Course Description Linux System Monitoring and Performance Tuning is an advanced 4-day hands-on lab course covering system architecture, performance characteristics, monitoring, benchmarking, and network performance tuning. | | | | | | Goal Linux System Monitoring and Performance Tuning is designed to teach the methodology of performance tuning and capacity planning for Linux. This class will cover: a discussion of system architecture with an emphasis on understanding the implications of system architecture on system performance, methods for testing the effects of performance adjustments (benchmarking), open source benchmarking utilities, methods for analyzing system performance and networking performance tuning configurations for specific application loads. |
