Hi Remi,
Below the info required. It seems strange that all counters are zero
because from the dnsdist web interface I can clearly see 6487 queries for
pool private. Unfortunately the mail doesn't allow me to send you the
screenshot. Also, my dnsdist is up and running well so, dnsdist must
receive queries
