How is DProbes different from KDB?
KDB is an interactive debugger that pauses the kernel and waits for input from the user. DProbes takes a pre-defined set of commands to execute at a probepoint. When the probe is triggered, these commands are interpreted and then control is returned to the probed program without a noticable interruption in the program. This is particularly useful for debugging in a production environment. DProbes is also commonly used to debug applications in user mode. It’s worth noting that DProbes can be used to trigger KDB when some pre-defined conditions are met.
