The Internal Statistics Window is used to view the internal state of the server and
the network adapters. It shows information that may be useful for debugging
and troubleshooting purposes.
Under normal conditions the Internal Statistics window does not need to be viewed.
If a problem with the product arises, support staff may ask you to open the window
and record some of the values that are displayed.
The window shows per-adapter information as well as server statistics. It contains the following
Network Adapter - Select a network adapter from the list.
The queue statistics relate to the selected adapter only (each adapter
has its own independent queues).
Internal ID - The ID used internally by the server to
represent the selected network adapter.
Send Queue Usage - The number of packets waiting to
be sent from the adapter.
Receive Queue Usage - The number of packets waiting to
be received by the adapter.
Domain Name Cache Usage - The number of domain names
that are currently stored on the server. Each connection that
flows through the server has its domain name recorded for
display purposes. The domain names are stored in a local cache
for fast lookups and to prevent strain on the operating systems
domain name lookup facility.
Subdomain Cache Usage - The number of subdomains
that are cached on the server. The subdomain cache is only
used for subdomains that are a subset of the domains in rules.
It is not used for general connection endpoints.
