binary packages and use it. If there are no packages ready for your system, you
will have to install from sources (section 2) instead.
-These operations are made for installing the LTTng 0.4.3 tracer on a
-linux 2.6.12-rc4-mm2 kernel. You will also find instructions for installtion of
-LTTV 0.6.x : the Linux Trace Toolkit Viewer.
-
-At this point, the -mm tree of the kernel is used because it has RelayFS support
-in it. In a nearby future, a vanilla kernel 2.6.14 will be used, as RelayFS has
-been integrated in the linux 2.6.14-rc series.
+These operations are made for installing the LTTng 0.5.0 tracer on a
+linux 2.6.14 kernel. You will also find instructions for installtion of
+LTTV 0.8.x : the Linux Trace Toolkit Viewer.
The following lttng patch is necessary to have the tracing hooks in the kernel.
The following ltt-control module controls the tracing.

[ ] Activate Linux Trace Toolkit Heartbeat Timer
- IMPORTANT : This is enabled by default : you must disable it!
