描述 SUMMARY
ab 是一個測試你Apache http服務器的工具，你可以通過這個工具指定一個單位時間內向apache發出的請求數量來看看你的Apache和機器配合的性能如何
選項 OPTIONS
- -A auth-username: password
-
支持基本的驗證證書,用戶名和密碼之間使用"冒號" : 分隔開,ab將以明文方式傳送過去.不管服務器是不是需要 ,也就是說你的服務器需要支持401認證. - -c concurrency
-
同時向服務器端發送的請求數目，默認狀態下是一次只執行一個http請求. - -C cookie-name= value
- Add a Cookie: line to the request. The argument is typically in the form of a name= value pair. This field is repeatable.
- -d
- Do not display the "percentage served within XX [ms] table". (legacy support).
- -e csv-file
- Write a Comma separated value (CSV) file which contains for each percentage (from 1% to 100%) the time (in milli seconds) it took to serve that percentage of the requests. This is usually more useful than the 'gnuplot' file; as the results are already 'binned'.
- -g gnuplot-file
- Write all measured values out as a 'gnuplot' or TSV (Tab separate values) file. This file can easily be imported into packages like Gnuplot, IDL, Mathematica, Igor or even Excell. The labels are on the first line of the file.
- -h
- 顯示使用說明
- -H custom-header
- 向請求包追加附加的標題字串.此參數應該是有效的標題行(header line)形式,通常使用冒號":"來分隔有效配對 (valid pair)例如 'Accept-Encoding: zip/zop;8 bit';
- -i
- 使用一個 http 頭(HEAD) 來替換 GET方法.不可以摻入POST 方法
- -k
- 允許http KeepAlive ；也就是說執行多個請求在一個 http 會話當中，默認是不允許的也就是no KeepAlive啦;)
- -n requests
- 執行一次測試會話的時候所發出的請求數目,默認是執行一個單一的請求當然了這樣的測試結果也就沒什么意義了
- -p POST-file
- 測試程序也就是ab,將向Apache server發送帶有HTTP POST 的請求.
- -P proxy-auth-username: password
- 當需要通過代理測試一台HTTP 服務器的時候而你的代理又需要用戶名密碼驗證,這時你可以使用這個選項,同樣用戶名與密碼之間使用冒號":"分隔開,ab將之以明文的方式發送出去,當然,前提是你的代理是處於407認證狀態的
- -q
- When processing more than 150 requests, ab outputs a progress count on stderr every 10% or 100 requests or so. The -q flag will suppress these messages.
- -s
- When compiled in (ab -h will show you) use the SSL protected https rather than the http protocol. This feature is experimental and very rudimentary. You probably do not want to use it.
- -S
- Do not display the median and standard deviation values, nor display the warning/error messages when the average and median are more than one or two times the standard deviation apart. And default to the min/avg/max values. (legacy support).
- -t timelimit
-
設置測試的時間的長短，使用這個選項ab將自動設置測試請求會話數目為50000，然后以你設置的時間為固定周期.默認狀態下是沒有時限的，也就是直到完成你所設置的請求數目為止. - -T content-type
- 內容類型標頭,使用在POST數據的時候.
- -v verbosity
- 設置冗余級別,4級打印出每個請求標頭的詳細信息, 3級打印出回應代碼(例如,404,200),2級打印出警告信息和指示消息
- -V
- 顯示版本號並且退出
- -w
- 打印輸出結果到HTML表中. 默認的表是兩列n行白底黑框
- -x <table>-attributes
- 使用字串來描述表的屬性,該屬性字串應該插入到<table 這里 >
- -X proxy[: port]
- Use a proxy server for the requests.
- -y <tr>-attributes
- 用於生成html表格每行的屬性名 (<tr>)
- -z <td>-attributes
- 用於生成html表格每列的屬性名 (<td>)
