Hello! I want to find out the response time from clients request up to dnsmasq's response (including the external answer!) to the client. But a look into the logfile - thought, easy to make a wrapper, because I am missing dnstap support - wonders me. For example, here a short excerpt, omitting the date, I cut out of a contueing block:
dnsmasq[315]: 86114 192.120.33.206/55020 query[PTR] 155.33.120.192.in-addr.arpa from 192.120.33.206 dnsmasq[315]: 86114 192.120.33.206/55020 /etc/dnsmasq.d/hosts 192.120.33.155 is proxy.lan.local dnsmasq[315]: 86115 192.120.33.206/55020 query[A] stackoverflow.com from 192.120.33206 dnsmasq[315]: 86115 192.120.33.206/55020 forwarded stackoverflow.com to 208.67.222.222 dnsmasq[315]: 86115 192.120.33.206/55020 reply stackoverflow.com is 151.101.193.69 dnsmasq[315]: 86115 192.120.33.206/55020 reply stackoverflow.com is 151.101.65.69 dnsmasq[315]: 86115 192.120.33.206/55020 reply stackoverflow.com is 151.101.129.69 dnsmasq[315]: 86115 192.120.33.206/55020 reply stackoverflow.com is 151.101.1.69 dnsmasq[315]: 86116 192.120.33.206/55020 query[A] alive.github.com from 192.120.33.206 dnsmasq[315]: 86116 192.120.33.206/55020 forwarded alive.github.com to 77.88.8.8 dnsmasq[315]: 86116 192.120.33.206/55020 reply alive.github.com is <CNAME> dnsmasq[315]: 86116 192.120.33.206/55020 reply live.github.com is 140.82.113.25 Am I right, that in the second column, is just a sequence number? Then, the first block would be easy to understand and I could use the timedifference (the time, were the loglines arrive in my warapper). The second block looks like dnsmasq is sending four responses, because of stackoverflow has four ip-addresses? Or does this mean, the query (of this second block) started at it's first line and was complete(!) at the sixt line and the answer to the client was one response packet? At least, the following "sequence" number then is logically different. The same pattern then is visible in the third block. Some comments would help me! Thanks so far, Manfred
