Dtrace course description
An advanced hands on course covering Dtrace. The DTrace utility, originally provided in the Solaris 10 Operating System but now being ported to more operating environments, allows a system administrator to monitor the operations of a system at both kernel and application levels. It is the fine detail and accurate timings that DTrace produces that can help to determine the root-cause of a software problem within minutes rather than days. This, 3 day course will teach administrators and developers how to apply the DTrace utility appropriately and correctly and also teach them how to program in the 'D' language, thereby allowing them to write their own DTrace scripts.
Who will benefit?
Advanced technical staff working with Solaris
Dtrace training course prerequisites
Tuning and troubleshooting UNIX.
Dtrace training course objectives
By the end of the course delegates will be able to:
- Monitor systems performance.
- Issue Dtrace commands.
- Create and execute Dtrace sripts.
- Monitor systems using Dtrace.
