Any counter in the "*_dns_error_total" realm indicates a potential DNS related problem.
Any counter in the "*_dns_error_total" realm (apart from the one for successful queries) indicates a potential DNS related problem.
However, we realized during the 0.4.7 release cycle that DNS errors are way too noisy and contain too many false positives to be useful for overload reporting purposes.
We therefore don't use them anymore for that purpose starting with 0.4.6.9 and 0.4.7.4-alpha. However, we still keep DNS metrics around to give the relay operator insight into what is going on with their relay.

### tor_relay_load_socket_total
These lines indicate the relay is running out of sockets.
If the number of opened sockets is close to or the same as total sockets available then this indicates the relay is running out of sockets.
The solution is to increase ``ulimit -n`` for the tor process.
