Gavin,

1. Make sure you are running the FC11 kernel 2.6.30 (any FC11 kernel) with
LTTng support. That is you need to patch the kernel of FC11 with LTTng
patches and should be loaded with all necessary LTTng kernel modules.

2. Once you make sure that CONFIG_LTT and other LTT options are enabled in
kernel, then you need to run "ltt-armall" for markers.

3. Now you should be ready to start the trace process with the command :

# lttctl -C -w /tmp/trace1 trace1

4. To stop tracing you run:

# lttctl -D trace1

5. Dump the output to a text file

# lttv -m textDump -t /tmp/trace1  > lttng-output.txt


For more information, you can follow the instructions  at :
