DNSCrypt overview
Shows dnscrypt-proxy's query_log in a nice graphical way by parsing its content with mtail.
How to use
- Download and install mtail
- Configure DNSCrypt-proxy daemon running to generate the
query_loginltsvformat - Save the content of the following mtail “program” to a text file
# mail "program" for DNSCrypt's query log (in ltsv format)
#
# Sample line:
# time:1608044190 host:127.0.0.1 message:www.ripe.net type:A return:PASS cached:0 duration:1 server:faelix-ch-ipv4
counter queries_total
counter queries by host, type, return, cached, server
# Binning should be adapted to the latency (in ms) you have with your DNSCrypt s ervers
