Re: Re: Re: [ltt-dev] Hi, everybody. i am a newbie here! whocouldtellmehow can i use LTTng ( i just need an example without LinuxTraceToolkitNextGeneration Manual) 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. -Srikant 2010/5/26 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 ?

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 2010/5/25 unbutun 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: The input data file /tmp/trace1/irq_state_0 does not contain a trace The input data file /tmp/trace1/module_state_0 does not contain a trace The input data file /tmp/trace1/syscall_state_0 does not contain a trace The input data file /tmp/trace1/softirq_state_0 does not contain a trace The input data file /tmp/trace1/metadata_0 does not contain a trace The input data file /tmp/trace1/swap_state_0 does not contain a trace (process: 2272): WARNING: Trace /tmp/trace1/ has no metadata tracefile (process: 2272): CRITICAL: cannot open trace /tmp/trace1 /usr/bin/lttv: line 15: 2270 Segmentation fault $0.real $* Do you know what's wrong of that?

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 : http://lttng.org/cgi-bin/gitweb.cgi?p=lttv.git;a=blob_plain;f=LTTngManual.html -Srikanth On Mon, May 24, 2010 at 5:44 PM, unbutun wrote: 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 ?
