|What's New in the Oracle Solaris Studio 12.3 Release Oracle Solaris Studio 12.3 Information Library|
DLight is an interactive graphical observability tool that uses Oracle Solaris Dynamic Tracing (DTrace) technology. DLight runs multiple DTrace scripts in a synchronized fashion, while showing you the output graphically, to help you trace a runtime problem in an application to the root cause.
The following features were added or changed in Oracle Solaris Studio 12.3 DLight.
A new Process Tree target enables you to profile a process and all the processes that it creates, graphically showing the following:
An aggregation of the microstates of all the threads of all the processes that DLight profiled with the Process Tree Target.
The microstate transitions in the form of a timeline for each thread of the target process and its child processes.
Locking statistics for the process and its children.
Aggregated CPU usage of all threads in all the targeted processes profiled across all the CPUs they are running on.
CPU-intensive areas in your program's process tree by displaying the functions in your program along with the CPU time used by the function and any functions it calls.
The Attach target, which is used to profile a single running process, was renamed to Process target.
The AMP target was removed.
