Tcprstat測試mysql響應時間

一、tcprstat工具安裝與使用

tcprstat 是一個基於 pcap 提取 TCP 應答時間資訊的工具，通過監控網路傳輸來統計分析請求的響應時間。

• 使用方法：
  tcprstat是安裝在server端，統計分析本地網絡卡地址請求的響應時間，可以用於臨時分析，也可定時任務做資訊收集

1、 下載安裝tcprstat

• x86_64位作業系統可以直接下載二進位制檔案使用。

步驟如下：
1、下載檔案 http://github.com/downloads/Lowercases/tcprstat/tcprstat-static.v0.3.1.x86_64
2、把下載的檔案移動到 /usr/bin
3、把檔名修改為 tcprstat
4、修改檔案許可權，增加執行許可權 chmod +x /usr/bin/tcprstat
 

• i686作業系統只能自己編譯。

2、tcprestat 使用

[[email protected] ~]#  tcprstat -p 3306 -t 1 -n 5 -I em1
tcprstat: invalid option -- 'I'
Usage: tcprstat [--port <port>] [--format=<format>] [--interval=<sec>]
             [--header[=<header>] | --no-header] [--iterations=<it>]
             [--read=<file>]
       tcprstat --version | --help

    --read <file>, -r    Capture from pcap file <file>, not live.
    --local <addresses>, -l
                         <addresses> is a comma-separated list of ip
                         addresses, which are used as the local list of
                         addresses instead of pcap getting the list.
                         This is useful when working with a pcap file got
                         from another host with different addresses.
    --port <port>, -p    Capture traffic only for tcp/<port>.
    --format <format>, -f
                         Output format. Argument is a string detailing
                         how the information is presented. Accepted codes:
                             %n - Response time count
                             %a - Response time media in microseconds
                             %s - Response time sum
                             %x - Response time squares sum
                             %m - Minimum value
                             %M - Maximum value
                             %h - Median value
                             %S - Standard deviation
                             %v - Variance (square stddev)
                             %I - Iteration number
                             %t - Timestamp since iteration zero
                             %T - Unix timestamp
                             %% - A literal %
                         Default is:
    "%T\t%n\t%M\t%m\t%a\t%h\t%S\t%95M\t%95a\t%95S\t%99M\t%99a\t%99S\n".
                         Statistics may contain a percentile between
                         the percentage sign and the code: %99n, %95a.
    --header[=<header>], --no-header
                         Whether to output a header. If not supplied, a
                         header is created out of the format. By default,
                         the header is shown.
    --interval <seconds>, -t
                         Output interval. Default is 10.
    --iterations <n>, -n
                         Output iterations. Default is 1, 0 is infinity

    --help               Shows program information and usage.
    --version            Shows version information.
