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 LTT has been mostly superseded by its successor [[LTTng]] (Linux Trace Toolkit Next Generation).

LTT allows the user to see in-depth information about the processes that were running during the trace period, including when context switches occurred, how long the processes were blocked for, and how much time the processes spent executing vs. how much time the processes were blocked. The data is logged to a text file and various console-based and graphical ([[GTK+]]) tools are provided for interpreting that data.
