The Solaris[tm] System Performance Management course introduces students to performance tuning principles, monitoring utilities and tuning tools for the Solaris Operating System (Solaris OS). The presentation includes a review of Solaris subsystems and the utilities provided to monitor system efficiency including vmstat, iostat, netstat, mpstat, nfsstat and sar. This revision also presents tools new to Solaris 10, including DTrace, alongside these well known utilities. The course format isolates each major system component that affects the system performance data. Case studies are used to illustrate how performance bottlenecks can be isolated, confirmed through analysis,and resolved through making adjustments to the system configuration. The Central Processing Units (CPUs), memory, and input/output (I/O) systems are reviewed to clarify standard techniques for monitoring each one. Monitoring and tuning virtual memory operations, UFS and ZFS file systems, and network efficiency are discussed as well. The course concludes with a more general examination of the full cycle of identifying and resolving performance impediments. The Solaris[tm] System Performance Management course includes lab exercises to reinforce skills development.
