Hi,

The namespace statedump and contexts feature has not been merged in
master yet. You can get it from my github in the "ns" feature branches.

https://github.com/mjeanson/lttng-modules/tree/ns
https://github.com/mjeanson/lttng-ust/tree/ns
https://github.com/mjeanson/lttng-tools/tree/ns

It's a bit out of date but should work as-is, or it can be easily
rebased on current master branches.


Cheers,

Michael

Hi,

I can't give you an exact time line, but within the next 3-4 weeks.

Test pid_ns in local build

[Polzer, Franz]

[-- Attachment #1.1: Type: text/plain, Size: 547 bytes --]

Hello,

I wanted to give the pid_ns context tracing a try and built LTTng from master, but I get the following error when applying this command:

lttng add-context -k -t procname -t pid -t vpid -t tid -t vtid -t pid_ns

Error: Unknown context type pid_ns

Maybe I need another branch to build from to get that feature in or forgot to enable the feature during building?

Where can I find documentation about the pid_ns tracing and how to test the current version of that implementation?

Thanks for your help and best regards,
Franz
