[lttng-dev] 回复： Enamebling namespace contexts

[Jonathan Rajotte-Julien]

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

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?
