Calculate clients per relay and bridge
To calculate clients per router it is possible to extrapolate the data from victoria metrics.
I think the correct queries should be the following.
For relays:
sum(max(desc_relay_dirreq_v3_responses{fingerprint="<fingerprint>"}) by (day) / 10
For bridges:
sum(sum_over_time(max(desc_bridge_dirreq_v3_responses{fingerprint="<fingerprint>"}))[24h]) by (day) / 10
Please do let me know if these do match up with current data displayed on relay-search.
