LTTng, the Linux Trace Toolkit Next Generation, is a highly efficient full system tracing solution toolchain. It is composed of several components to allow tracing of the kernel, of userspace, trace viewing and analysis and trace streaming. LTTng is open source software.
New Features: - LTTng 2.0 kernel modules build against a vanilla or distribution kernel, without need for additional patches, - Tracepoints, detailed syscall tracing (fast strace replacement), CPU Performance Monitoring Unit (PMU) counters, dynamic address/symbol probing (kprobes) and function call/return tracing (kretprobes support), - Have the ability to attach "context" information to events in the trace (e.g. any PMU counter, pid, ppid, tid, comm name, etc). All the extra information fields to be collected with events are optional, specified on a per-tracing-session basis (except for timestamp and event id, which are mandatory). - Allows non-root users part of the "tracing" group to perform kernel and userspace tracing. - Allows multiple tracing sessions to be active concurrently, each with its own instrumentation set. - Integrated interface for both kernel and userspace tracing, - Produces CTF (Common Trace Format) natively, (http://www.efficios.com/ctf) You can get a the current release "bundle" (recommanded set of packages) at the following URL: http://lttng.org/bundles/ Project website: http://lttng.org Download link: http://lttng.org/lttng2.0 (please refer to the README files for installation instructions and lttng-tools doc/quickstart.txt for usage information) Main changes since the last bundle: - Fixed lttng-sessiond file/directory creation rights handling. - Fixed 32-bit clock source overflow in lttng-ust.
