I am currently working on a new project called "libside" (see https://git.efficios.com/?p=libside.git;a=summary) which features support for compound types. However, we still need to do the heavy-lifting implementation work of integrating this with LTTng-UST. This is the plan towards supporting compound types in LTTng-UST. > I'd love to have confirmation that I did not just miss something :) > If LTTng UST is out for me I will probably try to use the ctf-writer > module of babeltrace 2 instead For now the ctf-writer modules of bt2 would be an alternative to consider, but remember that it is not designed for low-impact tracing such as lttng-ust. So it depends on how much tracer overhead/runtime impact you can afford in your use-case.
