The workload of the worker queries was 175784 respectively.įinally, measured in the last half hour, an average of 1 qps was performed. ![]() The packets cache had 4536 entries and 82% of queries were served from it. This ratio can be greater than 100% since additional queries could be needed to actually recurse the DNS and figure out the addresses of nameservers.Ġ% of queries were not performed because identical queries had gone out previously and failed, saving load on servers worldwide.Ģ17 outgoing tcp connections were done, there were 0 queries running at the moment and 9155 queries to authoritative servers saw timeouts. The outpacket/query ratio means that on average, 0.54 packets were needed to answer a question. Next a line with the sizes of maps that can be consulted by rec_control is printed. The record cache was consulted or modified 56041728 times, and 1583 of those accesses caused lock contention. There are 1773 items in the negative cache, items of which it is known that don’t exist and won’t do so for the near future.ġ8% of incoming questions not handled by the packets cache could be answered without any additional queries going out to the net.
