Hi, Srikanth
I do it as the following:
1. download the kernel 2.6.33.3 and patch patch-2.6.33.3-lttng-0.213.tar.gz ,
tar xzf them into /usr/src/kernel, move patch-2.6.33.3-lttng-0.213 to patches,
move patches into linux-2.6.33.3
2. quilt push -a
3. enabled the kernel LTTng in make menuconfig, just enable this and every
other is as default (kernel and LTTng)
4. build the kernel and install it
5. rpm -i the following:
libkcompat-devel-0.0-1.1.i386.rpm
liblttctl0-0.71-1.1.i386.rpm
liblttctl-devel-0.71-1.1.i386.rpm
liblttv0-0.12.17-1.1.i386.rpm
liblttv-devel-0.12.17-1.1.i386.rpm
liburcu0-0.2.3-alpha.1.1.i386.rpm
liburcu-devel-0.2.3-alpha.1.1.i386.rpm
ltt-control-0.71-1.1.i386.rpm
ltt-control-debug-0.71-1.1.i386.rpm
lttv-0.12.17-1.1.i386.rpm
lttv-debug-0.12.17-1.1.i386.rpm
6. run your command:
# lttctl -C -w /tmp/trace1 trace1
# lttctl -D trace1
all successful
but
# lttv -m textDump -t /tmp/trace1 > lttng-output.txt
failed, and said that there is no metadata in /tmp/trace1/metadata_0
is there anything wrong with my steps or anything else do i need to install or
config in my FC11 ?
Thanks, Advance
Any help would be much appreciated !

Gavin

主题： Re: [ltt-dev] Hi, everybody. i am a newbie here! who could tell mehow can i
use LTTng ( i just need an example without Linux Trace Toolkit NextGeneration
Manual)
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 trace14. To stop tracing you run:
# lttctl -D trace15. 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 :
