Trace compass with GDB trace format. [message #1801591]

I'm a new user of Trace compass. As I read, Trace compass built form CTF (Common Trace Format) data. So I have some question about GDB trace. Can Trace compass work with raw GDB Trace? Does Trace compass convert GDB trace to CTF trace to use? How about other Trace formats (does thet converted to CTF format or they have other parsers?). Thank you.

Hi Vien,

Trace Compass supports GDB traces but it's a separate feature that needs to be installed manually, unless you are using Eclipse IDE for C/C++ Developers.

You can install the feature from the main eclipse update site under Performance, Profiling and Tracing Tools > GDB Tracepoint Analysis.

Trace Compass will use the GDB debugger installed on the local host to parse the raw GDB trace events.

See the GDB Tracepoint Analysis User Guide for details:

Hi Vien,

The forum ate my reply. Patrick answered masterfully though.

I would like to add, trace compass supports many trace types. Here is a short list

GDB
BTF
Generic CTF
LTTng Kernel CTF
LTTng User Space CTF
Perf CTF*
FTrace*
FTrace Textual report*
ATrace (Android)*
UFTrace*
PCap
PCapNg (soon)
Maven*
Trace Compass*
Trace Event (chromium)*
Jaeger traces*
ROS LTTng User space CTF traces*
User defined text log support
User defined XML log support

* in the trace compass incubator

Also, please note you can make an 'experiment' with a set of these traces to merge them in time.

So if you have additional logs, you can annotate your GDB trace with them.

Cheers,

Matthew
