Brief History Almost 20 years of Linux tracing! We are all getting older. Tracing in Linux was non existant until the mid 2000’s. Took a while to be acknowledged as a real user need Developers worried about overhead, slowdown… Developers feared of being locked into an ABI Eventually pieces started being added, fragmented approach LTT (Linux Trace Toolkit) (1998)
Linux Trace Toolkit - Wikipedia
https://en.wikipedia.org/wiki/Linux_Trace_Toolkit
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 LTT has been mostly superseded by its successor LTTng (Linux Trace Toolkit Next Generation).
