[ltt-dev] Flight Recorder Testing on Linux-2.6.32

[skrishnakar@gmail.com (srikanth krishnakar)]

Hi Mathieu,

I am trying to run through the LTTng Flight Recorder test on kernel
Linux-2.6.32.13.  Here are the steps I have followed :


1. Compiled the kernel Linux-2.6.32 + Lttng support

2. Booted the Lttng kernel

3. Loaded all the necessary modules, followed by :

4. Ran "ltt-armall"

5. Then started the tracing in flight recorder mode as:

#  lttctl -C -w /tmp/trace3 -o channel.all.overwrite=1 trace3

6. Then destroyed the channels, for write process to take place:

# lttctl -D trace3


Correct me If i am going wrong in any of the above steps, that are necessary
for flight recorder testing.

What is the difference do I find in normal LTTng tracing and the Flight
Recorder mode ? What difference does the LTTV-GUI shows for LTTng Flight
recorder mode ?
(Is LKCD any way related to core dump tracing in Flight Recorder mode ?)

Are there any additional steps required for carrying out the tracing in
Flight recorder mode for CORE DUMP tracing.

All the steps i have followed are from :
http://lttng.org/cgi-bin/gitweb.cgi?p=lttv.git;a=blob_plain;f=LTTngManual.html#flight

Any pointers would be appreciated !!

Thanks in Advance !
