install the lttng tool set in my ubuntu 11.10.</div>
<div>After successful installation, i followed the getting

You may verify if kernel modules are loaded correctly. If not, then
there may be a problem while the installation. <br>
<br>
lsmod | grep lttng<br>
<br>
If not, you may try to load them and see if any error message
occurs:<br>
<br>
sudo modprobe lttng_tracer<br>
