Yes, LTTng supersedes LTT. It provides the ability to extract traces across execution layers (hypervisor, kernel, userspace) to perform performance analysis and debugging of applications at the system level. LTTng's approach differs from LTT in that it allows completely customizable instrumentation. We chose to provide that based on the previous LTT experience, where we have seen that adding instrumentation is very often required when digging deeply into a problem.
