I've only ever gotten an empty reply when trying to extract metrics
and I still do on Tor 4.6.7. I have some vague memory of the metrics
previously only being for hidden services.

All the metrics mentioned in the overload guide[1] seem to be missing.
Having a quick look at the Git repository, it seems that only
0.4.71-alpha and latest master contain the necessary changes for these
metrics.

Is my assumption correct or am I doing something wrong?

Cordially,
Andreas Kempe
