Ceph messages are transmitted using tcp, so the system isn't directly aware
of packet loss at any level. I suppose we could try and export messenger
reconnect counts via the admin socket, but that'd be a very noisy measure
-- it seems simplest to just query the OS or hardware directly?

Hi,
I've stumpled upon this a couple of times, where Ceph just stops
responding, but still works.
The cause has been package loss on the network layer, but Ceph doesn't
say anything.
Is there a debug flag for showing retransmission of package, or someway
to see that packages are lost?
Regards,
Josef
