I'm actually going to use vpp_get_stats (run remotely using ssh) for now. I'm using vpp_papi on a single testing server (so it connects to each of the VPP /run/vpp/api.sock over ssh forwarded sockets), so it doesn't have access to their shared memory segments. > > I am also exploring putting much more information into the stat segment, > essentially making it into an operational data store (RFC8342).
