Controls what activity counters a DNS server uses for logging.
The possible flags are:
total log the accumulated counters since reset or server
start.
sample log counters for each sampling interval.
performance log performance-related counters.
query log query-related counters.
errors log error-related counters.
security log security-related counters.
maxcounters log maxcounters-related counters.
ha log HA-related counters.
ipv6 log IPv6-related counters.
activity-summary-interval rangetime(60s-24h) default = 5m
Sets the seconds between DNS activity summary log messages,
if the activity-summary attribute is enabled in the server
log-settings. The default value is 5 minutes.
auth-db-cache-kbytes int default = 10240
Sets the kilobytes of internal (BTREE) cache that the authzone
database uses.
Note: This value is rounded up to the nearest 4KB boundary. For
example, an 81KB value is rounded up to 84KB.
axfr-multirec-default bool default = on
Determines the default multi-record AXFR choice for
foreign (remote) servers not found in remote server list.
Default is true (enable). Only old version Bind 8.x and
Microsoft NT version require this attribute to set false.
blackhole-acl amelist default = none
Blocks requests from clients and requests to servers listed in
this access control list. This list can contain hosts, network
addresses and/or other ACLs. Specifically configuring
communication with certain servers (i.e. forwarders) will not
be overridden by this setting.
cache-db-cache-kbytes int default = 10240
Sets the kilobytes of internal (BTREE) cache that the cache database
uses.
Note: This value is rounded up to the nearest 4KB boundary. For
example, an 81KB value is rounded up to 84KB.
checkpoint-interval rangetime(60m-1w) default = 3h
Sets the seconds that elapse between snapshots of zone information.
DNS records this information in the Zone Checkpoint database.
collect-sample-counters bool default = true
Switches counter sampling on and off.
default-negcache-ttl rangetime(0-24h) default = 0
