[lttng-dev] Enamebling namespace contexts

[Serica]

Hi,


ThI found that lttng is working on container awareness in this slides: https://archive.fosdem.org/2019/schedule/event/containers_lttng/attachments/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 containers. However, it seems like that lttng of current version doesn't support adding context pid_ns(Error: Unknown context type pid_ns). Do you know how to enable these features?


Thanks a lot.
Btw, have a nice holiday!
