11.4 sdt provider

The Statically Defined Tracing (SDT) provider creates probes at sites that a software programmer has formally designated. The SDT mechanism allows programmers to consciously choose locations of interest to users of DTrace and to convey some semantic knowledge about each location through the probe name.

As the sdt probes that are defined for the Oracle Linux kernel are likely to change over time, they are not listed here. Both the name stability and data stability of the probes are Private, which reflects the kernel's implementation and should not be interpreted as a commitment to preserve these interfaces. For more information about the DTrace stability mechanism, see Chapter 16, Stability.
