It looks like this code need to acquire a write lock.
| WriteLock wl(&g_qcount.queryLock); | ||
| QueryCountRecords::iterator it; | ||
| std::string qname; | ||
| for(it=g_qcount.records.begin(); it!=g_qcount.records.end(); ++it) { |

maybe use for(auto qname: g_qcount.records) here?

LGTM once travis is happy. Thank you! |

I like the
carbonServerfunctionality, but want to know more about the queries (or in my specific case: domains) that are served by dnsdist. So I implemented query counting, a per-record counter of the amount of requests for a specific record. This then is included in the data sent to carbon and can be adjusted/filtered by setting a Lua function withsetQueryCountFilter()
