default sub-buf size and count

default sub-buf size and count

Hello,

I was just wondering what the default values for the sub-buffer size and
the number of sub-buffers are. I attempted to print them out after setting
the channel with default attr, however both values appear 0.

Thanks for any insight,
Mosleh

This information is normally found in the man pages.

man lttng enable-channel, search for --subbuf-size=SIZE

Could you outline the session configuration used so we can see if the fact that
both value are zero is a bug?
