Podrobnosti:
The Solaris 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 kstat,sar, vmstat, iostat, netstat, mpstat, nfsstat, ps, prstat, pmap, the proc tools, truss, dtrace, the dtrace toolkit, cpustat, cputrack, busstat, swap, lockstat, and mdb. This revision also includes a section on resource management using zones and pools.The course format is divided into three major sections tools, OS theory, and strategy and actions. Solaris System Performance Management course includes lab exercises to reinforce skills development. The Labs will be of two types: 1. Learning and practice using the monitoring and configuration tools2. Problem solving labs where the student will have to determine the cause of a performance problem, or figure out a way to measure or load a subsystem. These labs will not have answers provided to the students.Students who can benefit from this course:Senior System Administrators and others concerned with monitoring effective performance of Solaris systems
