Introduction to DTrace (half day Tutorial)
Submitted by Tod McQuillin (@distalzou) on Monday, 4 April 2016
The tutorial’s objective is to provide an overview of DTrace and show the student how to become proficient with using DTrace to formulate queries about system behaviour and get the desired answers.
DTrace is a powerful tool developed by Sun Microsystems for analyzing system behaviour and troubleshooting problems on production systems in real time. The first release of DTrace was on Solaris, but DTrace has since been ported to other Unix-like systems including MacOS X and FreeBSD. DTrace is also available on Oracle Linux, and for other Linux systems using the freely available dtrace4linux project.
Students should be proficient with using the Unix operating system and should be familiar with Unix shells, text editors, and at least one programming language. To run exercises during the class, students should have their own laptop available running Solaris, FreeBSD, Mac OS X, or Linux with DTrace installed and enabled. A VM running on another system can also be used to run a DTrace enabled OS.
