[lttng-dev] Listing live sessions after a session is destroyed

[Marc-André Laperle]

Hi Jérémie,

Thank you for your response. I am seeing this problem with a different viewer than babeltrace that we are implementing in Trace Compass. I filled a bug here:
http://bugs.lttng.org/issues/853

> What do you mean by "creating a new viewer"?

I meant opening a new connection to relayd which will create a new "viewer" from relayd's perspective.

Thank you,
Marc-André

Hi Marc-André,

That does look like a bug. Would you mind opening a bug on
bugs.lttng.org describing the steps you take along with the babeltrace
(assuming this is the viewer you are using) and relayd verbose logs?
(launch both with -vvv)

What do you mean by "creating a new viewer"?

Regards,
Jérémie
