I am not CI/networking expert, but I will be more than happy to assist.

what I'm looking for if you ask "statistics on the network". Also, I have no experience with s390x except for deploying the Debian
software on the server setup by Phil. All the quirks of s390x are beyond me. I can provide logging from the host, but I'll need detailed instructions
of what people find useful to look at. Recently Antonio taught me a
trick to provide temporary access to a lxc container on any of our
hosts, so if it helps to be on the host (but inside lxc) we can provide
for that. Paul [1] |
