Description

I'm using lttng-tools 2.1.1.
The information in the trace path is incorrect when executing "lttng list" or "lttng list <session name>" after executing the following command sequence:

lttng create my

Session my created.
Traces will be written in /home/bernd/lttng-traces/my-20130220-103009

lttng list my

Tracing session my: [inactive]
Trace path: /home/bernd/lttng-traces/my-20130220-103009

lttng enable-event -a -k -s my --tracepoint

All kernel tracepoints are enabled in channel channel0

lttng enable-event -a -u -s my --tracepoint

All UST tracepoints are enabled in channel channel0

lttng enable-consumer -s my -u -U net://192.168.56.1 -e

URL net://192.168.56.1 set for UST session my.
Consumer enabled successfully

lttng list

1) my ([K]: net://[]:27951/y-27951/y-20130220-103009 [data: 0] -- [U]: net://192.168.56.1:5342/ [data: 5343]) [inactive]

The last command out put should show the correct path (/home/bernd/lttng-traces/my-20130220-103009) for the kernel since it uses the local consumer. This display error makes it hard to parse the trace path within the Eclipse LTTng Control (for LTTng 2.1 support).

Best Regards
Bernd

Late to the party! :(

But since 2.2, enable-consumer is now obsolete meaning you can only have a network destination for a session and not domain specific like previously.

Here are two use cases that basically show that this bug is fixed:

$ lttng create test -C tcp://1.1.1.2:8900 -D tcp://1.1.1.2
Control URL tcp://1.1.1.2:8900 set for session test
Data URL tcp://1.1.1.2 set for session test
Session test created.
$ lttng list test
Tracing session test: [inactive]
    Trace path: net4://1.1.1.2:8900/ [data: 5343]

and two custom ports:

lttng create test2 -C tcp://1.1.1.2:8900 -D tcp://1.1.1.2:111
Control URL tcp://1.1.1.2:8900 set for session test2
Data URL tcp://1.1.1.2:111 set for session test2
Session test2 created.
lttng list test2
Tracing session test2: [inactive]
    Trace path: net4://1.1.1.2:8900/ [data: 111]
