The Linux Trace Toolkit (LTT) is a set of tools that is designed to log program execution details from a patched Linux kernel and then perform various analyses on them, using console-based and graphical tools. LTT has been mostly superseded by its successor LTTng ( Linux Trace Toolkit Next Generation). If opte is set, then a list is output by the debug() function.
