[lttng-dev] tracing user event from multiple dockers

[lttng-dev] tracing user event from multiple dockers

Hello,

I have an application working with multiple dockers.
Each docker is a fedora O.S running an application.
The host is centos 8.5. This host will be upgraded to RHEL 9.2 in the near
future.
Is it possible that all traces from multiple dockers will all be written to
one metadata ?

versions:
lttng-tools-latest-2.13.tar.bz2
lttng-ust-latest-2.13.tar.bz2
userspace-rcu-latest-0.14.tar.bz2

Thank you,
Zvika

Hi Zvika,

To share a sessiond the LTTng home and run directories, and the shared 
memory should be shared between the containers.

Eg. https://github.com/mjeanson/gcloud-lttng/blob/master/pods/demo1.yaml.in

In a scenario with multiple sessionds (eg. one per container), the 
traces could be combined in post using babeltrace.

thanks,
kienan
