Re: [linuxtools-dev] Lttng2 issue
|
Hi Jessica,
There was a known bug in 1.0 where it would fail to validate a trace if
it contained a stream with only 1 packet . This is often the case with
small UST traces, since those do not have a lot of events.
As a workaround, you can use the "Common Trace Format -> Kernel Trace"
type. Some views will be empty, but the histogram, events table and
statistics should work.
Alternatively, you could update to Linux Tools 1.1. Instructions at
http://wiki.eclipse.org/Linux_Tools_Project/PluginInstallHelp
If either method does not fix your problem, please let us know, you
might be hitting something else.
Cheers,
Alexandre

When I tried to select trace type as "Common Trace Format->Generic CTF Trace", I'm getting "Type could not be set for one or more traces". If I import each individual files, e.g. channel0_0 and assign trace type for it, I'm also getting the same error.
