Subject: [lttng-dev] lttng enable-channel option for blocking
Message-ID: <4F992213.2090103@mentor.com>

There are use-cases where loosing an event is not acceptable.

Is there some way to make a userspace application block if the buffer is 
full (instead of discarding the event or overwriting an old event) ?

I'm thinking about something like:

lttng enable-channel myblockingchannel --block

I know I can increase the subbuf-size but sometimes this is not an 
option (embedded targets with less RAM).

A new channel option like --block would be a fine complement for the 
already existing options --discard and --overwrite.

What do you think ?
Thanks,
Paul
