<div dir="ltr"><div>Oyé Oyé, dear LTTng fellows!</div><div><br></div><div>I am proud to announce the availability of the first LTTng-Tools 2.7 -</div><div>"Herbe à Détourne" release candidate. As per usual, this release bears the</div><div>codename of a Québec-brewed beer.</div><div><br></div><div>Brewed with unrestrained amounts of Citra hop, the Herbe à Détourne is a</div><div>fantastic New World Tripel brewed by "Dieu du Ciel!". Aromas of mango,</div><div>cantaloupe melon and passion fruit, combined with a controlled bitter finish,</div><div>unite in making this smooth golden-orange beer stand apart.</div><div><br></div><div>We are still hard at work fixing a handful of last-minute issues (see our bug</div><div>tracker), integrating more tests for the latest features, and updating the</div><div>documentation before we make a final release available.</div><div><br></div><div>However, that doesn't mean you can't try out the latest features today!</div><div><br></div><div>--- Process (PID) Tracker ---</div><div>The new "track" and "untrack" commands allows the tracking of events associated</div><div>with specific PIDs, both in user space and kernel space.</div><div><br></div><div>For example, the following commands may be used to track all user space events</div><div>of PID "1234":</div><div>$ lttng create my_session</div><div>$ lttng track --userspace --pid 1234</div><div>$ lttng enable-event --userspace --all</div><div>$ lttng start</div><div><br></div><div>--- Python Logging Support ---</div><div>Following in the footsteps of the Java Util Logging and Log4J logging backend<br></div><div>support, which were introduced as part of LTTng 2.4 and LTTng 2.6 respectively,</div><div>this new version adds support for the Python logging backend. This means that</div><div>logging statements emitted by the Python logging module can now be collected as</div><div>part of user space traces by enabling events from the "python" domain.</div><div><br></div><div>$ lttng create my_session</div><div>$ lttng enable-event --python --all</div><div>$ lttng start</div><div><br></div><div>The lttngust Python module is provided as part of LTTng-UST 2.7.</div><div><a href="https://github.com/lttng/lttng-ust/tree/master/liblttng-ust-python-agent">https://github.com/lttng/lttng-ust/tree/master/liblttng-ust-python-agent</a></div><div><br></div><div>--- Kernel tracer filtering support ---</div><div>While LTTng-UST has provided support for event filtering for a long time,</div><div>it was not possible to perform kernel-side event filtering until now. As of this version,</div><div>Kernel space filters can be used in the same way as user space filters.</div><div><br></div><div>For instance, to trace only read() syscalls requesting more than 100 bytes:</div><div>$ lttng create my_session</div><div>$ lttng enable-event --kernel --syscall read --filter "count > 100"</div><div>$ lttng start</div><div><br></div><div>--- Kernel tracer wildcard support ---</div><div>Support for wildcards in event names is another feature that has been brought</div><div>from the user space tracer to the kernel tracer. This means that groups of</div><div>kernel space events can be enabled at once using the wildcard notation.</div><div><br></div><div>The tracing of all block device or scheduling events can be enabled using a</div><div>single command:</div><div><br></div><div>$ lttng enable-event --kernel block*</div><div>or</div><div>$ lttng enable-event --kernel sched*</div><div><br></div><div>--- File-backed user space buffers ---</div><div><span style="font-size:12.8000001907349px">This new LTTng-UST feature allows the mapping of ring buffers onto filesystems.</span></div><div><span style="font-size:12.8000001907349px">This proves useful</span><span style="font-size:12.8000001907349px"> in combination with pramfs or DAX+pmem (Linux kernels 4.1+</span></div><div><span style="font-size:12.8000001907349px">for DAX and </span><span style="font-size:12.8000001907349px">4.2+ for pmem) to store tracer ring buffers in persistent </span><span style="font-size:12.8000001907349px">memory upon</span></div><div><span style="font-size:12.8000001907349px">an unexpected system reboot.</span></div><div><span style="font-size:12.8000001907349px"><br></span></div><div><span style="font-size:12.8000001907349px">These buffers can be salvaged and converted to regular CTF traces using the</span></div><div><span style="font-size:12.8000001907349px">newly introduced lttng-crash utility to see the events that led to a crash.</span></div><div><br></div><div>--- Support for clock and getcpu plugins ---</div><div>In the interest of keeping LTTng as unintrusive as possible, LTTng 2.7</div><div>introduces support for platform-specific plug-ins providing custom</div><div>implementations of getcpu() (user space) and clock sources for both kernel and</div><div>user space tracers.</div><div><br></div><div>getcpu override plugins can prove useful in cases where direct hardware access</div><div>is available for architecture-specific registers storing the CPU number, and</div><div>where those should be used instead of the Linux kernel sched_getcpu()</div><div>vDSO/syscall.</div><div><br></div><div>clock override plugins, which may be implemented as shared objects (user space)</div><div>or kernel modules (kernel space) may prove userful in cases where direct</div><div>hardware access to architecture-specific clocks is available, and when it should</div><div>be used in place of the Linux kernel Monotonic clock.</div><div><br></div><div>--- tracelog() support ---</div><div>LTTng-UST 2.7 provides a number of facilities to smoothen the transition of</div><div>applications from logging to tracing in the form of tracelog() tracepoints.</div><div>LTTng-UST 2.7's announcement covers this feature in more detail:</div><div><br></div><div><a

these new features in depth in an upcoming post</div><div>on the official LTTng blog at <a href="http://lttng.org/blog">lttng.org/blog</a> in time for the final
