Hello,
I plan to deploy dnsmasq on a medium sized network as primary caching
DNS for both workstations and servers - 1500 workstations / 600 servers.
I'm currently testing it on a test subnet with around 50 workstations
and have been wondering about the cache stats.
dnsmasq[27357]: time 1372247969
dnsmasq[27357]: cache size 2000, 0/65220 cache insertions re-used
unexpired cache entries.
dnsmasq[27357]: queries forwarded 22019, queries answered locally 11238
dnsmasq[27357]: server xx.xx.xx.164#53: queries sent 5812, retried or
failed 0
dnsmasq[27357]: server xx.xx.xx.165#53: queries sent 5812, retried or
failed 0
dnsmasq[27357]: server xx.xx.xx.114#53: queries sent 16201, retried or
failed 30
dnsmasq[27357]: server xx.xx.xx.115#53: queries sent 925, retried or
failed 10
What exactly means "0/65220 cache insertions re-used unexpired cache
entries"??
It means dnsmasq handled 65520 names lookups that needed to be sent to
upstream severes that nothing was thrown out of the cache before
reaching the end of its time-to-live, to make room for a newer name. For
the first number, smaller is better.
Simon.
