During an incident investigation involving LVS it was pointed out that the "load balancers" dashboard shows connections/bytes/packets and icmp, though it isn't immediately obvious the former refer to LVS only whereas the latter (icmp) is for the host interface.
The task is mostly as a followup and FYI with the dashboard "owners" i.e. Traffic
I've put a text panel explaining this fact on top of the dashboard and changed the graph titles to differentiate host/lvs. https://grafana.wikimedia.org/dashboard/db/load-balancers
