Hi Mathieu,
Arch: PowerPC
Just to re-write the steps for running the LTTng-0.65 for kernel
linux-2.6.29, please comments on the steps performed for tracing, or if any
modification required:
1. Create debugfs directory
$ mkdir /mnt/debugfs
2. Get the backup of fstab
$ cp /etc/fstab /etc/fstab.lttng.bkp
3. Write to /etc/fstab for automounting of debugfs
$ echo "debugfs /mnt/debugfs debugfs rw 0 0" >> /etc/fstab
4.You can automate at boot time loading the ltt-control module by :
a.> Get the bakup of /etc/modules
$ cp /etc/modules /etc/modules.bkp
b.> Now execute the following :
echo ltt-trace-control >> /etc/modules
echo ltt-marker-control >> /etc/modules
echo ltt-tracer >> /etc/modules
echo ltt-serialize >> /etc/modules
echo ltt-relay >> /etc/modules
echo ipc-trace >> /etc/modules
echo kernel-trace >> /etc/modules
echo mm-trace >> /etc/modules
echo net-trace >> /etc/modules
echo fs-trace >> /etc/modules
echo jbd2-trace >> /etc/modules
echo ext4-trace >> /etc/modules
echo syscall-trace >> /etc/modules
echo trap-trace >> /etc/modules

6. Dump output trace in text format:

7. Dump output to a .lttng file for viewing in GUI environment :
$ lttv -m textDump -t /tmp/trace1 >* Lttng-out.lttng *
Please correct my steps, How can I create LTTng file that can be viewed
graphically (unlike earlier method of tracedump > $
lttv -m textDump -t tracedump > Lttng-out.lttng
)
How Can I get the tracedump for particular trace ?
Thanks in Advance !!

Hm ? The gui environment works directly on the binary trace, not on a
text output.

Just run:
lttv-gui /tmp/trace1
If you cannot run the GUI on your target machine, simply copy the
/tmp/trace1 directly to a different machine (can be powerpc, x86...) and
run lttv-gui from there.
