Greetings everyone (including LTTng elves), The lttng-tools project provides a session daemon (lttng-sessiond) that acts as a tracing registry, the "lttng" command line for tracing control, a lttng-ctl library for tracing control and a lttng-relayd for network streaming.
Introducing the "Époque Opaque", the E version of the LTTng toolchain. I invite everyone to read the small description of this version by doing "lttng version" :). This is the feature freeze and first 2.4.0 release candidate. This version adds multiple fixes and some new *awesome* features. 1) Live support. It's now possible to stream traces (kernel and UST) while they being extracted meaning a relayd can now receive traces live and a viewer can attach to it to process the trace while running. The "--live" has been added to lttng create command that sets up a live tracing session. See doc/live-reading-howto.txt and doc/live-reading-protocol.txt for more detail on that feature. 2) Java Util Logging support. With a special LTTngAgent located in lttng-ust project (liblttng-ust-jul) to trace JUL events and gather UST traces with them. The -j/--jul domain has been added to lttng command line so you can list the possible JUL Logger object and enable/disable them. It is the same as using the UST or Kernel domain. As of now, filters and loglevel are ignored with the JUL domain. 3) Event exclusion. Thanks to JP Ikaheimonen for that contribution!, a -x/--exclusion option has been added to lttng enable-event that allows the user to exclude events from being enabled. 4) New health check API now integrated in lttng-sessiond, lttng-relayd and the lttng-consumerd. Please see include/lttng/health.h for more details on this new API. Thanks to everyone that worked on this release! Too many people to thank but just a special one to Julien Desfossez that worked like a *beast* for the incredible live feature (and 4000 more lines of code to maintain... :P). Please report ANY issues to bugs.lttng.org or through that mailing list. Using it is testing it!
