> All the SSL metrics registered in {{SSLUtils.cc}} are specified as {{RECD_INT}}, but they are all actually counters and should be specified as {{RECD_COUNTER}}.
> The sync function is sometimes given as {{RecRawStatSyncSum}} and sometimes {{RecRawStatSyncCount}}. Although these functions are identical, we should choose just one.
> Note that the SSL session cache metrics are a little quirky. They *are* actually counters, but they use {{SSL_SET_COUNT_DYN_STAT}} rather than {{SSL_INCREMENT_DYN_STAT}}. AFAICT the right way to do this would be to use {{SSL_INCREMENT_DYN_STAT}} but clear the {{SSL_CTX}} counters on every pass. The way it is done now seems like it would lead to incorrect values when the session cache is cleared or SSL state is reloaded. Unfortunately I don't see an OpenSSL API to clear the counters, so more research is needed there.
