Subject: [lttng-dev] lttng enable-channel option for blocking
Date: Thu, 26 Apr 2012 12:23:15 +0200 [thread overview]
Message-ID: <4F992213.2090103@mentor.com> (raw)
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
