The DNSSRV_RECORD_STATS structure has DNS server statistics related to record usage. This structure MUST be formatted as follows:

0	1	2	3	4	5	6	7	8	9	1 0	1	2	3	4	5	6	7	8	9	2 0	1	2	3	4	5	6	7	8	9	3 0	1

Header (8 bytes): A structure of type DNSSRV_STAT_HEADER (section 2.2.10.2.1).

InUse (4 bytes): The number of resource records currently allocated by the server.

Used (4 bytes): The cumulative number of resource records allocated by the server.

Return (4 bytes): The cumulative number of resource records freed by the server.

Memory (4 bytes): The amount of memory, in bytes, currently allocated for resource records by the server.

CacheTotal (4 bytes): The cumulative number resource records cached by the server.

CacheCurrent (4 bytes): The number of resource records currently cached by the server.

CacheTimeouts (4 bytes): The cumulative number of resource records that have been freed from the DNS server's cache.

SlowFreeQueued (4 bytes): Some cached record types, such as NS and SOA, are not immediately freed to the pool of allocated records, instead they are placed in a timeout queue and returned after this timeout expires. This is the cumulative count of such slow-free records that have been entered into the timeout queue.

SlowFreeFinished (4 bytes): The number of slow frees (see SlowFreeQueued above) that have been completed.
