Hi,

ThI found that lttng is working on container awareness in this slides:= https://archive.fosdem.org/2019/schedule/event/containers_lttng/attachment= s/slides/3419/export/events/attachments/containers_lttng/slides/3419/lttng_= containers_fosdem19.pdf

On page #13, there is a command: = ; lttng add-context -k -t procname -t pid -t vpid -t tid -t vtid -t pid_ns,= where pid_ns and other namespace identifiers are very useful for tracing c= ontainers.

What version of= LTTng do you use (output of "lttng --version"), and what is the output of = "lttng add-context --list" ?
