1LTTNG LIVE
2----------
3
4This is a brief howto for using the Babeltrace with LTTng live protocol.
5LTTng live allows the user to read a trace while it is running.
6
7In order to create a live LTTng session, please refer to the LTTng
8documentation (version >= 2.4).
9
10Once the session is created and Babeltrace is installed, you can list the
11sessions with :
12$ babeltrace -i lttng-live net://<your-relayd-hostname>
13
14The output should look like this :
15net://localhost/host/myhostname/mysessionname (timer = 1000000, 5 stream(s), 0 client(s) connected)
16
17It means that the session mysessionname on the host myhostname is currently
18streaming its data to the relayd on localhost.
19
20To attach to this session and start receiving the trace :
21$ babeltrace -i lttng-live net://localhost/host/myhostname/mysessionname
22
23You should now see trace data flowing in your console when events are produced.
24
25To report bugs, please use the same procedure as reporting bugs to Babeltrace,
26but don't forget to add the -v to the commands above to provide enough debug
27information.
