The output may vary depending on the command line parameters given. + Possible output with a brief explanation of each element is listed below. +

+ +
+
Server Software
+
The value, if any, returned in the server 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.
+ +
Server Hostname
+
The DNS or IP address given on the command line
+ +
Server Port
+
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.
+ +
SSL/TLS Protocol
+
The protocol parameters negotiated between the client and server. + This will only be printed if SSL is used.
+ +
Document Path
+
The request URI parsed from the command line string.
+ +
Document Length
+
This is size in bytes of the first succesfully returning document. + If the document length changes during testing, the response is + considered an error.
+ +
Concurrency Level
+
The number of concurrent clients used during the test
+ +
Time taken for tests
+
This is the time taken from the moment the first socket connection + is created to the moment the last response is recieved
+ +
Complete requests
+
The number of successful responses recieved
+ +
Failed requests
+
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.
+ +
Write errors
+
The number of errors that failed during write (broken pipe).
+ +
Non-2xx responses
+
The number of responses that were not in the 200 series of response + codes. If all responses were 200, this field is not printed.
+ +
Keep-Alive requests
+
The number of connections that resulted in Keep-Alive requests
+ +
Total body sent
+
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.
+ +
Total transferred
+
The total number of bytes received from the server. This number + is essentially the number of bytes sent over the wire.
+ +
HTML transferred
+
The total number of document bytes received from the server. This + number excludes bytes received in HTTP headers
+ +
Requests per second
+
This is the number of requests per second. This value is the result + of dividing the number of requests by the total time taken
+ +
Time per request
+
The average time spent per request. The first value is calculated + with the formula concurrency * timetaken * 1000 / done + while the second value is calculated with the formula + timetaken * 1000 / done
+ +
Transfer rate
+
The rate of transfer as calculated by the formula + totalread / 1024 / timetaken
