LTTng » LTTng-tools

After adding a context to an event there is no way to retrieve the context information, i.e. lttng list <session name> doesn't show the context information.
I think, a general rule should be, that things that can be configured should be able to be retrieved.

I used commit aeb968923d1245f4cb2be1eed2ab7b8b5eb45cf8

Here is an example sequence. As you can see "lttng list my"-comand doesn't show the context information:

lttng create my

Session my created.

Traces will be written in /home/eedbhu/lttng-traces/my-20120224-130527

lttng enable-event sched_switch -k

kernel event sched_switch created in channel channel0

lttng add-context -k -e sched_switch -t pid

kernel context pid added to event sched_switch

lttng list my

Tracing session my: [inactive]
