- tristate "LTTng kernel tracer"
- depends on TRACEPOINTS
- help
- The LTTng 2.0 Tracer Toolchain allows integrated kernel and
- user-space tracing from a single user interface: the "lttng"
- command. See http://lttng.org website for the "lttng-tools"
- user-space tracer control tools package and the "babeltrace"
- package for conversion of trace data to a human-readable
- format.
-
- LTTng features:
- - System-wide tracing across kernel, libraries and
- applications,
- - Tracepoints, detailed syscall tracing (fast strace replacement),
- Function tracer, CPU Performance Monitoring Unit (PMU) counters
- and kprobes 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).
- - Precise and fast clock sources with near cycle-level
- timestamps,
- - Efficient trace data transport:
- - Compact Binary format with CTF,
- - Per-core buffers ensures scalability,
- - Fast-paths in caller context, amortized synchronization,
- - Zero-copy using splice and mmap system calls, over disk,
- network or consumed in-place,
- - Multiple concurrent tracing sessions are supported,
- - Designed to meet hard real-time constraints,
- - Supports live streaming of the trace data,
- - Produces CTF (Common Trace Format) natively (see
- http://www.efficios.com/ctf).

-LTTng 2.0 modules
-
-Mathieu Desnoyers
-November 1st, 2011
-
-LTTng 2.0 kernel modules is currently part of the Linux kernel staging
-tree. It features (new features since LTTng 0.x):
-
-- Produces CTF (Common Trace Format) natively,
- (http://www.efficios.com/ctf)
-- Tracepoints, Function tracer, CPU Performance Monitoring Unit (PMU)
- counters, kprobes, and kretprobes support,
-- Integrated interface for both kernel and userspace tracing,
-- 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).
-
-To build and install, you need to select "Staging" modules, and the
-LTTng kernel tracer.
-
-Use lttng-tools to control the tracer. LTTng tools should automatically
-load the kernel modules when needed. Use Babeltrace to print traces as a
-human-readable text log. These tools are available at the following URL:
-http://lttng.org/lttng2.0
-
-Please note that the LTTng-UST 2.0 (user-space tracing counterpart of
-LTTng 2.0) is now ready to be used, but still only available from the
-git repository.
-
-So far, it has been tested on vanilla Linux kernels 2.6.38, 2.6.39 and
-3.0 (on x86 32/64-bit, and powerpc 32-bit at the moment, build tested on
-ARM). It should work fine with newer kernels and other architectures,
-but expect build issues with kernels older than 2.6.36. The clock source
-currently used is the standard gettimeofday (slower, less scalable and
-less precise than the LTTng 0.x clocks). Support for LTTng 0.x clocks
-will be added back soon into LTTng 2.0. Please note that lttng-modules
-2.0 can build on a Linux kernel patched with the LTTng 0.x patchset, but
-the lttng-modules 2.0 replace the lttng-modules 0.x, so both tracers
-cannot be installed at the same time for a given kernel version.
-
-* Note about Perf PMU counters support
-
-Each PMU counter has its zero value set when it is attached to a context with
-add-context. Therefore, it is normal that the same counters attached to both the
-stream context and event context show different values for a given event; what
-matters is that they increment at the same rate.
+++ /dev/null
-Please contact Mathieu Desnoyers <mathieu.desnoyers@efficios.com> for
-questions about this TODO list. The "Cleanup/Testing" section would be
-good to go through before integration into mainline. The "Features"
-section is a wish list of features to complete before releasing the
-"LTTng 2.0" final version, but are not required to have LTTng working.
-These features are mostly performance enhancements and instrumentation
-enhancements.
-
-TODO:
-
-A) Cleanup/Testing
-
- 1) Remove debugfs "lttng" file (keep only procfs "lttng" file).
- The rationale for this is that this file is needed for
- user-level tracing support (LTTng-UST 2.0) intended to be
- used on production system, and therefore should be present as
- part of a "usually mounted" filesystem rather than a debug
- filesystem.
-
- 2) Cleanup wrappers. The drivers/staging/lttng/wrapper directory
- contains various wrapper headers that use kallsyms lookups to
- work around some missing EXPORT_SYMBOL_GPL() in the mainline
- kernel. Ideally, those few symbols should become exported to
- modules by the kernel.
-
- 3) Test lib ring buffer snapshot feature.
- When working on the lttngtop project, Julien Desfossez
- reported that he needed to push the consumer position
- forward explicitely with lib_ring_buffer_put_next_subbuf.
- This means that although the usual case of pairs of
- lib_ring_buffer_get_next_subbuf/lib_ring_buffer_put_next_subbuf
- work fine, there is probably a problem that needs to be
- investigated in
- lib_ring_buffer_get_subbuf/lib_ring_buffer_put_subbuf, which
- depend on the producer to push the reader position.
- Contact: Julien Desfossez <julien.desfossez@polymtl.ca>
-
-
-B) Features
-
- 1) Integration of the LTTng 0.x trace clocks into
- LTTng 2.0.
- Currently using mainline kernel monotonic clock. NMIs can
- therefore not be traced, and this causes a significant
- performance degradation compared to the LTTng 0.x trace
- clocks. Imply the creation of drivers/staging/lttng/arch to
- contain the arch-specific clock support files.
- * Dependency: addition of clock descriptions to CTF.
- See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
- for the LTTng 0.x git tree.
-
- 2) Port OMAP3 LTTng trace clocks to x86 to support systems
- without constant TSC.
- * Dependency: (B.1)
- See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
- for the LTTng 0.x git tree.
-
- 3) Implement mmap operation on an anonymous file created by a
- LTTNG_KERNEL_CLOCK ioctl to export data to export
- synchronized kernel and user-level LTTng trace clocks:
- with:
- - shared per-cpu data,
- - read seqlock.
- The content exported by this shared memory area will be
- arch-specific.
- * Dependency: (B.1) && (B.2)
- See: http://git.lttng.org/?p=linux-2.6-lttng.git;a=summary
- for the LTTng 0.x git tree, which has vDSO support for
- LTTng trace clock on the x86 architecture.
-
- 3) Integrate the "statedump" module from LTTng 0.x into LTTng
- 2.0.
- * Dependency: addition of "dynamic enumerations" type to CTF.
- See: http://git.lttng.org/?p=lttng-modules.git;a=shortlog;h=refs/heads/v0.19-stable
- ltt-statedump.c
-
- 4) Generate system call TRACE_EVENT headers for all
- architectures (currently done: x86 32/64).
-
- 5) Define "unknown" system calls into instrumentation/syscalls
- override files / or do SYSCALL_DEFINE improvements to
- mainline kernel to allow automatic generation of these
- missing system call descriptions.
-
- 6) Create missing tracepoint event headers files into
- instrumentation/events from headers located in
- include/trace/events/. Choice: either do as currently done,
- and copy those headers locally into the lttng driver and
- perform the modifications locally, or push TRACE_EVENT API
- modification into mainline headers, which would require
- collaboration from Ftrace/Perf maintainers.
-
- 7) Poll: implement a poll and/or epoll exclusive wakeup scheme,
- which contradicts POSIX, but protect multiple consumer
- threads from thundering herd effect.
-
- 8) Re-integrate sample modules from libringbuffer into
- lttng driver. Those modules can be used as example of how to
- use libringbuffer in other contexts than LTTng, and are
- useful to perform benchmarks of the ringbuffer library.
- See: http://www.efficios.com/ringbuffer
-
- 9) NOHZ support for lib ring buffer. NOHZ infrastructure in the
- Linux kernel does not support notifiers chains, which does
- not let LTTng play nicely with low power consumption setups
- for flight recorder (overwrite mode) live traces. One way to
- allow integration between NOHZ and LTTng would be to add
- support for such notifiers into NOHZ kernel infrastructure.
-
- 10) Turn drivers/staging/lttng/ltt-probes.c probe_list into a
- hash table. Turns O(n^2) trace systems registration (cost
- for n systems) into O(n). (O(1) per system)
-
- 11) drivers/staging/lttng/probes/lttng-ftrace.c:
- LTTng currently uses kretprobes for per-function tracing,
- not the function tracer. So lttng-ftrace.c should be used
- for "all" function tracing.
-
- 12) drivers/staging/lttng/probes/lttng-types.c:
- This is a currently unused placeholder to export entire C
- type declarations into the trace metadata, e.g. for support
- of describing the layout of structures/enumeration mapping
- along with syscall entry events. The design of this support
- will likely change though, and become integrated with the
- TRACE_EVENT support within lttng, by adding new macros, and
- support for generation of metadata from these macros, to
- allow description of those compound types/enumerations.

-LTTng system call tracing
-
-1) lttng-syscall-extractor
-
-You need to build a kernel with CONFIG_FTRACE_SYSCALLS=y and
-CONFIG_KALLSYMS_ALL=y for extraction. Apply the linker patch to get your
-kernel to keep the system call metadata after boot. Then build and load
-the LTTng syscall extractor module. The module will fail to load (this
-is expected). See the dmesg output for system call metadata.
-
-2) Generate system call TRACE_EVENT().
-
-Take the dmesg metadata and feed it to lttng-syscalls-generate-headers.sh, e.g.,
-from the instrumentation/syscalls directory. See the script header for
-usage example.
-
-After these are created, we just need to follow the new system call additions,
-no need to regenerate the whole thing, since system calls are only appended to.
