Re: [linuxtools-dev] How does Eclipse parse LTTng2 / CTF traces ?

[Francois Chouinard <fchouinard@xxxxxxxxx>]

Hi, 

If your traces were generated on the same CPU, the events are de-facto correlated on their timestamp and they can be visualized in TMF.

The steps are pretty straightforward:

- Create a tracing project

- Import all your traces in the Traces folder (assign the correct trace type)

- Create an experiment (in the Experiment folder)

- For that experiment, select the traces you want to visualize (from the Traces folder)

- Open the experiment (double-click)

You can find more details in the User Guide (in the Help section) or in the wiki (

http://wiki.eclipse.org/index.php/Linux_Tools_Project/LTTng/User_Guide)

Hi,

I've another question related to this topic:
I've generated several traces in the same time
- a LTTng one, at kernel level,
- several CTF traces, at user-land level (with UST)

Is there a way to display more than one trace (eg both kernel and user-land) in eclipse ?

And you will have additional features by using the Eclipse tracing and monitoring framework (it doesn't only support LTTng)

  - Searching, Filtering, Highlighting
  - GDB tracepoint integration
  - Sequence diagram framework

Hi Martin

The LTTng integration of Eclipse as part of the Linux Tools project comes with a CTF parser. The CTF parser is written in Java and hence doesn't require any native libraries. I haven't heard of any other CTF parsers than the Eclipse version or babeltrace.


You can use the Eclipse CTF parser standalone [1] or as part of the Tracing and Monitoring Framework (TMF) [2]. Both features you can get from the Linux Tools update site [3]. The source code you can get from the Linux Tools repository [4]. Note, if you're interested what is coming up for the Kepler release, then check the lttng-kepler branch.

[1] CTF parser standalone
For that, install the "CTF - Common Trace Format" feature.

[2] TMF integration of CTF parser
For that install the "LTTng - Linux Tracing Toolkit" feature. This also includes the Eclipse feature TMF and CTF feature from [1]. Note that this feature also comes with a remote tracer control for LTTng 2 (Kernel and UST).

[3] Linux Tools Update site
http://download.eclipse.org/linuxtools/update

[4] Source code
git://git.eclipse.org/gitroot/linuxtools/org.eclipse.linuxtools.git

If you have any questions please let us know.

Best Regards
Bernd

Hi,



We're looking at integrating some LTTng2 / CTF support into our
product, in order to visualize lttng-ust traces.

Since we've got an existing visualization framework, parsing the CTF
traces is one key concern.



We've come across babeltrace, but we were wondering whether there's
other solutions available.



How does Linuxtools parse CTF ... is it implemented in Java or does it
use native libs ?

Are you guys aware of any alternative solutions ?



Thanks,
Martin
