<p>The output may vary depending on the command line parameters given.
Possible output with a brief explanation of each element is listed below.
</p>
<dl>
<dt>Server Software</dt>
<dd>The value, if any, returned in the <var>server</var> HTTP header
of the first successful response. This includes all characters in the
header from beginning to the point a character with decimal value of 32
(most notably: a space or CR/LF) is detected.</dd>
<dt>Server Hostname</dt>
<dd>The DNS or IP address given on the command line</dd>
<dt>Server Port</dt>
<dd>The port to which ab is connecting. If no port is given on the
command line, this will default to 80 for http and 443 for
https.</dd>
<dt>SSL/TLS Protocol</dt>
<dd>The protocol parameters negotiated between the client and server.
This will only be printed if SSL is used.</dd>
<dt>Document Path</dt>
<dd>The request URI parsed from the command line string.</dd>
<dt>Document Length</dt>
<dd>This is size in bytes of the first succesfully returning document.
If the document length changes during testing, the response is
considered an error.</dd>
<dt>Concurrency Level</dt>
<dd>The number of concurrent clients used during the test</dd>
<dt>Time taken for tests</dt>
<dd>This is the time taken from the moment the first socket connection
is created to the moment the last response is recieved</dd>
<dt>Complete requests</dt>
<dd>The number of successful responses recieved</dd>
<dt>Failed requests</dt>
<dd>The number of requests that were considered a failure. If the
number is greater than zero, another line will be printed showing the
numer of requests that failed due to connecting, reading, incorrect
content length, or exceptions.</dd>
<dt>Write errors</dt>
<dd>The number of errors that failed during write (broken pipe).</dd>
<dt>Non-2xx responses</dt>
<dd>The number of responses that were not in the 200 series of response
codes. If all responses were 200, this field is not printed.</dd>
<dt>Keep-Alive requests</dt>
<dd>The number of connections that resulted in Keep-Alive requests</dd>
<dt>Total body sent</dt>
<dd>If configured to send data as part of the test, this is the total
number of bytes sent during the tests. This field is omitted if the test
did not include a body to send.</dd>
<dt>Total transferred</dt>
<dd>The total number of bytes received from the server. This number
is essentially the number of bytes sent over the wire.</dd>
<dt>HTML transferred</dt>
<dd>The total number of document bytes received from the server. This
number excludes bytes received in HTTP headers</dd>
<dt>Requests per second</dt>
<dd>This is the number of requests per second. This value is the result
of dividing the number of requests by the total time taken</dd>
<dt>Time per request</dt>
<dd>The average time spent per request. The first value is calculated
with the formula <code>concurrency * timetaken * 1000 / done</code>
while the second value is calculated with the formula
<code>timetaken * 1000 / done</code></dd>
<dt>Transfer rate</dt>
<dd>The rate of transfer as calculated by the formula
<code>totalread / 1024 / timetaken</code></dd>
