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.
