[lttng-dev] Question about zero metadata

[changz]

Hi all,

I tried to generate one event and view the trace at run-time. It didn't 
work because metadata was zero.
And then I found metadata couldn't be dumped to disk when sub-buffer 
were not filled(i.e. consumer daemon didn't read data from ring-buffer).
And seems no timer to flush it because I waited for very long time. Once 
I stopped lttng or the application, metadata got ready at once.

My lttng version is 2.01. Is this a known issue?

Thanks
Zheng
