> I found the statistics of HostDB and DNS are not precise, see the following:
> {code}
> proxy.process.hostdb.total_lookups 286951594
> proxy.process.hostdb.total_hits 277568738
> proxy.process.dns.total_dns_lookups 23238887
> proxy.process.dns.lookup_successes 8952696
> proxy.process.dns.lookup_failures 332447
> {code}
> calculation:
> {code}
> 286951594 - 277568738 = 9382856
> 8952696 + 332447 = 9285143
> 9382856 - 9285143 = 97713
> {code}
> I have two question:
> 1.why ?
> proxy.process.hostdb.total_lookups - proxy.process.hostdb.total_hits !=
> proxy.process.dns.lookup_successes + proxy.process.dns.lookup_failures
> 2.why?
> proxy.process.dns.lookup_successes + proxy.process.dns.lookup_failures !=
> proxy.process.dns.total_dns_lookups
> anyone can show me the reason? thanks in advance!
