Average Queue Length
The Average Queue Length shows the average number of connections in the queue over the last
one-minute, ve-minute, and 15–minute intervals.
This setting is not tunable.
Average Queuing Delay
The Average Queueing Delay is the average amount of time a connection spends in the
connection queue. This represents the delay between when a request connection is accepted by
the server and when a request processing thread begins servicing the request. It is the Ticks
Spent divided by the Total Connections Queued, and converted to milliseconds.
This setting is not tunable.
Ticks Spent
A tick is a system-dependent value and provided by the tickPerSecond attribute of the server
element in stats.xml. The ticks spent value is the total amount of time that connections spent
in the connection queue and is used to calculate the average queueing delay.
This setting is not tunable.
Total Number of Connections Added
The new connections added to the connection queue. This setting is not tunable.
HTTP Listener (Listen Socket) Information
The following HTTP listener information includes the IP address, port number, number of
acceptor threads, and the default virtual server. For tuning purposes, the most important eld in
the HTTP listener information is the number of acceptor threads.
You can have many HTTP listeners enabled for virtual servers, but at least one is enabled for
your default server instance (usually http://0.0.0.0:80). The monitoring information
available through the Admin Console does not show the HTTP listener information, because
that information is available in the Admin Console on the conguration's HTTP Listeners tab.
The following is an example of how the HTTP listeners information appears in perfdump:
