Yes good point.
The only thing we have available is the heartbeat that should read like so:
log_notice(LD_HEARTBEAT,
"Our onion service%s received %u v2 and %u v3 INTRODUCE2 cells "
"and attempted to launch %d rendezvous circuits.",
num_services == 1 ? "" : "s",
hs_stats_get_n_introduce2_v2_cells(),
hs_stats_get_n_introduce2_v3_cells(),
hs_stats_get_n_rendezvous_launches());
Those counters don't get reset so to get the rate one need to compare between
two heartbeats (default is every 6h).
Thus, if any big popular service out there (no need to give the .onion) can
tell us the rate they see, it would be grand!
Thanks!
David
