Course Description

The Solaris System Performance Management course provides an introduction to performance tuning principles and monitoring tools for the Solaris Operating Environment (Solaris OE). This course covers the principles of performance tuning and usage of performance measurement tools such as sar, vmstat, iostat, netstat, and nfsstat. Central processing unit (CPU), memory, and input/output (I/O) bottlenecks are described and solutions are recommended. Determining virtual file system performance is also covered. The Solaris System Performance Management course includes lab exercises that allow students to analyze Solaris OS-related performance issues.

Who Can Benefit

Senior system administrators and system maintainers.
