3 monit machines probe 2 recursive DNS, 2 sec timeout, 2 times, 2 cycles,
120 minute cycle, with the standard
"
if failed port 53 use type udp protocol dns
...
"
an Orion machine probes the DNSs, also
a couple days ago, the orion machine reported DNS failure on one DNS
server for 1+ hours, while 3 monit machines didn't send any DNS alert,
and did not log even 1 DNS timeout.
what does monit do to monit port 53? still just query for
"." zone?
