AFAIK, Tracecompass have a CTF reader and have multiple extension point to
analyze the data.

Linux kernel trace data are understood based on a model of the kernel state
transition. A ctf trace could be translated based on the model that
Tracecompass uses.

Hi Ravindra,

I'm sending the reply also to the tracecompass mailing list, where it is
more on topic.

From what I understand, you have a CTF trace and would like to implement
a specific trace type from it, for example, to be able to add custom
analyses for this specific type. Right?

You can read the developer documentation on how to add new trace types
[1]. You may want to take a look at the LttngKernelTrace class for an
example of such extension of CTF Trace [2]. There are a few more around
the code, looking at the class hierarchy for CtfTmfTrace will show you
which ones.

Kernel traces need to implement IKernelTrace. This interface provides an
event layout (IKernelAnalysisEventLayout) which will define which events
in the trace correspond to common "concepts" of the kernel, like
sched_switches, syscalls, irqs, etc. That's how any kernel trace format
like ftrace, perf and lttng can use common analyses made for kernel. You
would need to implement this event layout for your own trace types.

Hi,

Thanks to all for suggestions. Let me describe the problem in more detail.

I have a QEMU(it is virtualization software like VMware etc.) instance
which is running some applications. The QEMU application can generate Trace
Data in CTF format which I want to transfer it to Trace Compass for
analyzing it.

I would like to know if there is a way to transfer CTF to Trace Compass in
a real-time manner using TCP/UDP.

and

How can I convert CTF Trace Data to LTTng? Since TraceCompass already
understands LTTng Trace Data.

P.S: I am a student working on Tracing project at my University.

Thanks

Thanks that is much clearer, I think.

So you have a user space application that generates a trace. It is virtualized, and you want to open it in trace compass to analyze it.


> I would like to know if there is a way to transfer CTF to Trace Compass in a real-time manner using TCP/UDP.


Would scp work? Just asking.


>How can I convert CTF Trace Data to LTTng? Since TraceCompass already understands LTTng Trace Data.


The CTF trace should be openable in Trace Compass. You won't have as many pretty graphs and whatnot, but you can get some basic analyses done with searching and filters. If you want some more advanced analyses, you can code an XML analysis, or use any language you want and parse it to make a LAMI report. Finally you can make your own analysis (and even commit it to the incubator! 😉 😉 ).


The important questions to ask in my opinion are :

  *   what are you looking to solve?
  *   what problem are you facing?


Once those questions are solved, we can move on to selecting the form of solution that is ideal for you.


Thanks for the interest,

Matthew.

Trace Compass does not support live traces. It is made for post-mortem analyses, so it works only on complete trace. We briefly supported live traces a few years back, but that made the code much more complicated, so this support was dropped. TraceCompass is not made for trace monitoring!

LTTng does support relaying the data over the network (see https://lttng.org/docs/v2.10/#doc-sending-trace-data-over-the-network). But Trace Compass does not open traces that are not terminated. The 2.11 version (not yet released) and master also support session rotation, so you can have traces in chunks of say 1 minutes and whenever a chunk is closed, it is ready to be opened by Trace Compass. This is as close to live trace analysis as you can get.

With an LTTng kernel trace, you can get all that. Add a UST trace to it and you can correlate both traces together.

Question related to LTTng

Hi Developers,

I am working on a project where I want Trace Compass to analyze and display
some information. I wanna ask a few things:

Q1. Is there any way to extend Trace Compass to work trace data in CTF
format?

Q2. How trace data(CTF) can be converted to Linux kernel trace data(LTTng)
which Trace Compass already understands?

Thanks
