Still, LTTng 2.6 adds some interesting +features. + +LTTng 2.5 already supported the instrumentation and tracing of +[Java applications](#doc-java-application) through `java.util.logging` +(JUL). LTTng 2.6 goes one step further by supporting +Apache log4j 1.2. +The new log4j domain is selected using the `--log4j` option in various +commands of the `lttng` tool. + +LTTng-modules has supported system call tracing for a long time, +but until now, it was only possible to record either all of them, +or none of them. LTTng 2.6 allows the user to record only a specific +subset of system call events, e.g.: + +
+lttng enable-event --kernel --syscall open,fork,chdir,pipe
+
+ +Finally, the `lttng` command line tool cannot only communicate with +humans as it used to do, but also with machines thanks to its new +[machine interface](#doc-mi) feature. diff --git a/toc/docs.yml b/toc/docs.yml index b7c505c..fe9e3f4 100644 --- a/toc/docs.yml +++ b/toc/docs.yml @@ -1,5 +1,7 @@ title: The LTTng Documentation cats: + - id: whats-new + title: What's new in LTTng 2.6? - id: nuts-and-bolts title: Nuts and bolts - id: installing-lttng -- 2.34.1
