[jira] [Created] (TS-4262) Some imprecise statistics of stats_over_http plugin

taoyunxing created TS-4262:
------------------------------

             Summary: Some imprecise statistics of stats_over_http plugin
                 Key: TS-4262
                 URL: https://issues.apache.org/jira/browse/TS-4262
             Project: Traffic Server
          Issue Type: Bug
          Components: Plugins
            Reporter: taoyunxing


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:
286951594 - 277568738 = 9382856
8952696 +332447 = 9285143
9382856 - 9285143 = 97713

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? thinks in advance!
