Is it possible to load the LTTng tools with a Red Hat or CentOS version 7 Real Time kernel? If yes, can it be done using the EfficiOS LTTng packages or only by building the packages from source code?
The LTTng kernel tracer works with a range of Preempt-RT kernel versions.
It is tested in CI on the Preempt-RT kernel branches currently maintained
by preempt-rt developers. However, it does not currently cover the
3.8.13-rt27.34 kernel listed on the RHEL page, and the EfficiOS
packages for RHEL do not currently target their Preempt-RT kernel.
