[unbutun]

Hi,

just as the title, i have install lttng on FC11. and don't know how to use it to trace the kernel, 

is there anyone who is very kind to tell me about that without care about my junior question ?


Thanks Advance

[ltt-dev] Hi, everybody. i am a newbie here! who could tell me how can i use LTTng ( i just need an example without Linux Trace Toolkit Next Generation Manual)

[srikanth krishnakar]

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 :

http://lttng.org/cgi-bin/gitweb.cgi?p=lttv.git;a=blob_plain;f=LTTngManual.html

[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)

[unbutun]

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 !

Regards,

Gavin

I think you have missed the following command here, before starting the
trace;

*# ltt-armall*

Then you follow with the below commands !!!

I think you have missed the following command here, before starting the
trace;

*# ltt-armall*

Then you follow with the below commands !!!

[ltt-dev] Hi, everybody. i am a newbie here! who could tellmehow can i use LTTng ( i just need an example without Linux Trace ToolkitNextGeneration Manual)

[srikanth krishnakar]

Gavin,

Please make sure you have run the following command's in sequence :

Before proceeding, run the following script:

--------------------------------------------------------------
#!/bin/bash
mkdir /mnt/debugfs
echo "debugfs  /mnt/debugfs debugfs  defaults   0  0" >> /etc/fstab
echo "debugfs Mounted"
echo ltt-filter >> /etc/modules
echo ltt-statedump  >> /etc/modules
echo ltt-kprobes  >> /etc/modules
echo ltt-marker-control >> /etc/modules
echo ltt-serialize >> /etc/modules
echo ltt-trace-control >> /etc/modules
echo ltt-userspace-event >> /etc/modules

#probes
echo block-trace >> /etc/modules
echo fs-trace >> /etc/modules
echo ipc-trace >> /etc/modules
echo kernel-trace >> /etc/modules
echo lockdep-trace >> /etc/modules
echo mm-trace >> /etc/modules
echo net-extended-trace >> /etc/modules
echo net-trace >> /etc/modules
echo pm-trace >> /etc/modules
echo rcu-trace >> /etc/modules
echo syscall-trace >> /etc/modules
echo trap-trace >> /etc/modules
--------------------------------------------------------------

*Now Reboot the target, and proceed with the below steps !! You should be
now able to get the trace output. *

1.* ltt-armall*

(The above is required to connect all the marker's, else you'll end up with
Zero sized trace file, as you have shown here)

2. *lttctl -C -w /tmp/trace1 trace1*

(Now carry on with you normal process on the system, till then your trace
data will be collected, then after some time run the below command to assure
that all events are logged into the trace files)

3.* ** lttctl -D trace1*

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

*If you are following the same steps, then show me the output of command ->
"*ltt-armall*" .

-Srikanth*

[ltt-dev] Hi, everybody. i am a newbie here! who could tellmehow can i use LTTng ( i just need an example without Linux Trace ToolkitNextGeneration Manual)

[srikanth krishnakar]

Gavin,

Please make sure you have run the following command's in sequence :

Before proceeding, run the following script:

--------------------------------------------------------------
#!/bin/bash
mkdir /mnt/debugfs
echo "debugfs  /mnt/debugfs debugfs  defaults   0  0" >> /etc/fstab
echo "debugfs Mounted"
echo ltt-filter >> /etc/modules
echo ltt-statedump  >> /etc/modules
echo ltt-kprobes  >> /etc/modules
echo ltt-marker-control >> /etc/modules
echo ltt-serialize >> /etc/modules
echo ltt-trace-control >> /etc/modules
echo ltt-userspace-event >> /etc/modules

#probes
echo block-trace >> /etc/modules
echo fs-trace >> /etc/modules
echo ipc-trace >> /etc/modules
echo kernel-trace >> /etc/modules
echo lockdep-trace >> /etc/modules
echo mm-trace >> /etc/modules
echo net-extended-trace >> /etc/modules
echo net-trace >> /etc/modules
echo pm-trace >> /etc/modules
echo rcu-trace >> /etc/modules
echo syscall-trace >> /etc/modules
echo trap-trace >> /etc/modules
--------------------------------------------------------------

*Now Reboot the target, and proceed with the below steps !! You should be
now able to get the trace output. *

1.* ltt-armall*

(The above is required to connect all the marker's, else you'll end up with
Zero sized trace file, as you have shown here)

2. *lttctl -C -w /tmp/trace1 trace1*

(Now carry on with you normal process on the system, till then your trace
data will be collected, then after some time run the below command to assure
that all events are logged into the trace files)

3.* ** lttctl -D trace1*

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

*If you are following the same steps, then show me the output of command ->
"*ltt-armall*" .

-Srikanth*

[ltt-dev] Hi, everybody. i am a newbie here! who couldtellmehow can i use LTTng ( i just need an example without Linux TraceToolkitNextGeneration Manual)

[unbutun]

Hi, srikanth

I know my fault is the version of Lttng lttctl lttv

Now, it's work, and have output of lttv -m textDump -t /tmp/trace1

in my enviorment,   there is only  ltt-control- 0.68-19062009.tar.gz  linux-2.6.29.tar.gz lttv-0.12.12-05032009.tar.gz   patch-2.6.29-lttng-0.1222.tar.gz
without ltt-usertrace-0.6.tar.gz

But,  use lttv-gui,  show there unknow_process in process tag, and show MODULE_UNKNOW in mode_types

 what's wrong of that ? 

is there any option which needed to choose in menuconfig ?

or  anyother  i need to do ?

Thanks, Advance

And thank you for your kind

Regards,

Gavin

2010/5/25 unbutun <unbutun at sohu.com>

No, Srikanth, i do everything in the Linux Trace ToolkitNextGeneration Manual 

and 
# lttctl -C -w /tmp/trace1 trace1


# lttctl -D trace1
all successful

but there is nothing in /tmp/trace1/ files (these files' size is 0 )

# lttv -m textDump -t /tmp/trace1  

got the error:

Do you know what's wrong of that?

I do it as the following:

    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

I think you have missed the following command here, before starting the trace;

# ltt-armall 

Then you follow with the below commands !!!


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,

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 : http://lttng.org/cgi-bin/gitweb.cgi?p=lttv.git;a=blob_plain;f=LTTngManual.html

No, Srikanth, i do everything in the Linux Trace ToolkitNextGeneration Manual 

and 
# lttctl -C -w /tmp/trace1 trace1


# lttctl -D trace1
all successful

but there is nothing in /tmp/trace1/ files (these files' size is 0 )

# lttv -m textDump -t /tmp/trace1  

got the error:

Do you know what's wrong of that?

I think you have missed the following command here, before starting the trace;

# ltt-armall 

Then you follow with the below commands !!!


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 ?

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 : http://lttng.org/cgi-bin/gitweb.cgi?p=lttv.git;a=blob_plain;f=LTTngManual.html

[ltt-dev] Hi, everybody. i am a newbie here! who couldtellmehow can i use LTTng ( i just need an example without Linux TraceToolkitNextGeneration Manual)

[unbutun]

Hi, srikanth

I know my fault is the version of Lttng lttctl lttv

Now, it's work, and have output of lttv -m textDump -t /tmp/trace1

in my enviorment,   there is only  ltt-control- 0.68-19062009.tar.gz  linux-2.6.29.tar.gz lttv-0.12.12-05032009.tar.gz   patch-2.6.29-lttng-0.1222.tar.gz
without ltt-usertrace-0.6.tar.gz

But,  use lttv-gui,  show there unknow_process in process tag, and show MODULE_UNKNOW in mode_types

 what's wrong of that ? 

is there any option which needed to choose in menuconfig ?

or  anyother  i need to do ?

Thanks, Advance

And thank you for your kind

Gavin,

Please make sure you have run the following command's in sequence :

Before proceeding, run the following script:

--------------------------------------------------------------
#!/bin/bash
mkdir /mnt/debugfs
echo "debugfs  /mnt/debugfs debugfs  defaults   0  0" >> /etc/fstab
echo "debugfs Mounted"
echo ltt-filter >> /etc/modules
echo ltt-statedump  >> /etc/modules
echo ltt-kprobes  >> /etc/modules
echo ltt-marker-control >> /etc/modules
echo ltt-serialize >> /etc/modules
echo ltt-trace-control >> /etc/modules
echo ltt-userspace-event >> /etc/modules

#probes
echo block-trace >> /etc/modules
echo fs-trace >> /etc/modules
echo ipc-trace >> /etc/modules
echo kernel-trace >> /etc/modules
echo lockdep-trace >> /etc/modules
echo mm-trace >> /etc/modules
echo net-extended-trace >> /etc/modules
echo net-trace >> /etc/modules
echo pm-trace >> /etc/modules
echo rcu-trace >> /etc/modules
echo syscall-trace >> /etc/modules
echo trap-trace >> /etc/modules
--------------------------------------------------------------

Now Reboot the target, and proceed with the below steps !! You should be now able to get the trace output. 

1. ltt-armall

(The above is required to connect all the marker's, else you'll end up with Zero sized trace file, as you have shown here)

2. lttctl -C -w /tmp/trace1 trace1

(Now carry on with you normal process on the system, till then your trace data will be collected, then after some time run the below command to assure that all events are logged into the trace files)

3. lttctl -D trace1

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

If you are following the same steps, then show me the output of command -> "ltt-armall" .

[srikanth krishnakar]

Copy your /tmp/trace1 to /root/trace1

then from LTTV-GUI add the trace directory /root/trace1

Now you  should be able to see the data.

Copy your /tmp/trace1 to /root/trace1

Hi, srikanth

I know my fault is the version of Lttng lttctl lttv

Now, it's work, and have output of lttv -m textDump -t /tmp/trace1

in my enviorment,   there is only  ltt-control- 0.68-19062009.tar.gz  linux-2.6.29.tar.gz lttv-0.12.12-05032009.tar.gz   patch-2.6.29-lttng-0.1222.tar.gz
without ltt-usertrace-0.6.tar.gz

But,  use lttv-gui,  show there unknow_process in process tag, and show MODULE_UNKNOW in mode_types

 what's wrong of that ? 

is there any option which needed to choose in menuconfig ?

or  anyother  i need to do ?

Thanks, Advance

And thank you for your kind

Gavin,

Please make sure you have run the following command's in sequence :

Before proceeding, run the following script:

--------------------------------------------------------------
#!/bin/bash
mkdir /mnt/debugfs
echo "debugfs  /mnt/debugfs debugfs  defaults   0  0" >> /etc/fstab
echo "debugfs Mounted"
echo ltt-filter >> /etc/modules
echo ltt-statedump  >> /etc/modules
echo ltt-kprobes  >> /etc/modules
echo ltt-marker-control >> /etc/modules
echo ltt-serialize >> /etc/modules
echo ltt-trace-control >> /etc/modules
echo ltt-userspace-event >> /etc/modules

#probes
echo block-trace >> /etc/modules
echo fs-trace >> /etc/modules
echo ipc-trace >> /etc/modules
echo kernel-trace >> /etc/modules
echo lockdep-trace >> /etc/modules
echo mm-trace >> /etc/modules
echo net-extended-trace >> /etc/modules
echo net-trace >> /etc/modules
echo pm-trace >> /etc/modules
echo rcu-trace >> /etc/modules
echo syscall-trace >> /etc/modules
echo trap-trace >> /etc/modules
--------------------------------------------------------------

Now Reboot the target, and proceed with the below steps !! You should be now able to get the trace output. 

1. ltt-armall

(The above is required to connect all the marker's, else you'll end up with Zero sized trace file, as you have shown here)

2. lttctl -C -w /tmp/trace1 trace1

(Now carry on with you normal process on the system, till then your trace data will be collected, then after some time run the below command to assure that all events are logged into the trace files)

3. lttctl -D trace1

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

If you are following the same steps, then show me the output of command -> "ltt-armall" .

No, Srikanth, i do everything in the Linux Trace ToolkitNextGeneration Manual 

and 
# lttctl -C -w /tmp/trace1 trace1


# lttctl -D trace1
all successful

but there is nothing in /tmp/trace1/ files (these files' size is 0 )

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 : http://lttng.org/cgi-bin/gitweb.cgi?p=lttv.git;a=blob_plain;f=LTTngManual.html

Copy your /tmp/trace1 to /root/trace1 

then from LTTV-GUI add the trace directory /root/trace1

Now you  should be able to see the data.

# ltt-armall 

Then you follow with the below commands !!!


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 !

Regards,

Gavin

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 : http://lttng.org/cgi-bin/gitweb.cgi?p=lttv.git;a=blob_plain;f=LTTngManual.html
