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!


Serica

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

Thanks, 

Mathieu

Hi,

> The version of my lttng is: lttng (LTTng Trace Control) 2.10.7 - KeKriek.

Please upgrade to lttng 2.12.x. Container awareness was added in the 2.12 release
cycle.

Cheers
