Logging in DNS
There are two main phrases in logging:
•
Channels specify where the data is logged.
•
Categories specify what kind of data (queries, updates, statistics, and so on) has to
be logged in specified channels.
Standard channels are:
•
file
•
syslog
•
stderr
•
null
Standard categories are:
•
default
•
general
•
database
•
security
•
config
•
resolver
•
xfer-in
•
xfer-out
•
notify
•
client
•
unmatched
•
network
•
update
•
queries
•
dispatch
•
lame-servers
Each category of data can be sent to one or more channels. In Figure 5-1
, queries are
logged to a file, and statistics data is logged both to a file and to syslog.
