The DTraceschedprovider allows the tracing of events related to CPU scheduling in the 4BSD and ULE schedulers. Thesched:::change-pri() probe fires when a thread's active scheduling priority is about to be updated. The first two arguments are the thread whose priority is about to be change...
The dtrace command converts probe descriptions defined in file.d into a probe header file via the -h option or a probe description file via the -G option. OPTIONS -h generate a systemtap header file. -G generate a systemtap probe

The fasttrap provider provides a DTrace probe that fires each time a user process executes an instruction. The pid provider allows for the dynamic creation of DTrace probes corresponding to instruction locations inside any user process specified using a process ID and an instruction address or symb...
