> 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!
