Hi Alexandre, I got the metadata_0 and ust_0, which are in different directories, from a single invocation of usttrace. After copying metadata_0 and ust_0 into same directory, I used LTTV to open that directory and got the following error:
lttv -m textDump -t 9341_5652200832964231168 ** ERROR **: Undescribed event 1 in channel ust aborting... /home/jizhai/MyLocal/LTTng/bin/lttv: line 15: 14715 Aborted $0.real $* As you mentioned, if there is endian problem, how to solve it? Thanks!

You have to give it the one containing the metadata_* and ust_* files directly. However from your tarball, your metadata_0 and ust_0 files are in different subdirectories. Is this what you obtained from a single invocation of usttrace? If so then it means your different channels end up in separate traces, and this is definitely not normal behavior. If you put both ust_0 and metadata_0 files in the same directory, and open that directory with LTTv, what do you get? I couldn't open it from here, but I think it has to do with different endianness.
