Solaris Dynamic Performance Tuning and Troubleshooting with DTrace

Prerequisites:

To succeed fully in this course, students should be able to administer the Solaris 10 Operating System, have a general understandaing of the Solaris kernel, and have some programming experience such as Perl or C

Course Description:

The Dynamic Performance Tuning and Troubleshooting with DTrace course provides students with the ability to use DTrace to diagnose application and system problems. This course replaces SA-325-S10.

Who Can Benefit:

Students who can benefit from this course are experienced system administrators, service support personnel, kernel developers, and application program developers

Upon completion of this course, students should be able to:

• Use DTrace to find the source of intermittent problems.
• Use DTrace to look at the cause of performance problems.
• Use DTrace to help debug applications.
• Find System problems with DTrace
• Troubleshoot DTrace script problems.

This course includes the following modules:

DTrace Fundamentals

• Describe the features of DTrace
• Describe the DTrace architecture

Using DTrace

• Examining performance problems using DTrace
• Use DTrace to obtain information about system calls
• Create D Scripts that Use Arguments

Debug Applications with DTrace

• Use DTrace to profile an application
• Use DTrace to access application variables
• Use DTrace to find transient system call errors
• Use DTrace to determine the names of files being opened

Finding System Problems with DTrace

• Use DTrace to access kernel variables
• Use DTrace to obtain information about read calls
• Use DTrace to do anonymous tracing
• Use DTrace to do speculative tracing
• Explain the privileges necessary to run DTrace operations

Troubleshooting DTrace Problems

• Describe how to lessen the performance impact of DTrace
• Describe how to use and tune DTrace buffers
• Debug DTrace scripts
