Wusage 8.0 Manual
dns Option
To reach this option in the configuration file editor,
follow these steps:
1. Edit Configuration
2. DNS Resolution (IPs->Names)
If you prefer to manually edit your configuration files,
use the following syntax for this option:
Example
dns on
dns off
Description
If set to on, the DNS Resolution (IPs->Names) (dns) option indicates
that wusage should attempt to look up the host names
of sites for which the access log contains
only IP addresses.
This is important: if your log
already contains full host names for most
sites, the DNS Resolution (IPs->Names) (dns) option is
not needed. It is not
likely that wusage will succeed in looking
up the names of sites that your web server
could not determine for itself, and a great
deal of time could be wasted in the attempt.
If your log does not contain host names,
then you may wish to turn on the dns
option. Be aware that DNS (Domain Name Service)
resolution takes time. However, Wusage 8.0 and above
can resolve several hundred IP addresses per second,
provided that your connection speed is adequate.
The old fast option, which was rarely understood
and could not be used to generate the top domains report,
has been removed. If encountered in an existing configuration
file, this setting will be treated as dns on.
See also the Cache DNS Results for This Many Days (dnscachedays) option,
which controls the reuse of DNS information from one run
of Wusage to another, and the Fake DNS (fakedns) option, useful
within company Intranets. Users should also examine the
Maximum time in seconds for each DNS lookup (dnslookupseconds) option.
