Tcprstat测试mysql响应时间
一、tcprstat工具安装与使用
tcprstat 是一个基于 pcap 提取 TCP 应答时间信息的工具，通过监控网络传输来统计分析请求的响应时间。
- 使用方法：
tcprstat是安装在server端，统计分析本地网卡地址请求的响应时间，可以用于临时分析，也可定时任务做信息收集
1、 下载安装tcprstat
- x86_64位操作系统可以直接下载二进制文件使用。
步骤如下：
1、下载文件 http://github.com/downloads/Lowercases/tcprstat/tcprstat-static.v0.3.1.x86_64
2、把下载的文件移动到 /usr/bin
3、把文件名修改为 tcprstat
4、修改文件权限，增加执行权限 chmod +x /usr/bin/tcprstat- i686操作系统只能自己编译。
2、tcprestat 使用
[root@sql ~]# 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.
- 参数说明
命令行参数 简短形式 类型 描述 默认值
--format -f 字符串 输出格式化字符串 ”%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”
--help 显示帮助信息
--interval -t 数字 监控多少秒输出一次统计 10
--iterations -n 数字 迭代执行的次数 0 意味着无限循环
--local -l 字符串 本级ip地址列表
--port -p 数字 端口
--read -r 字符串 pcap文件路径
--no-header 字符串 输出不显示头信息
--header 字符串 指定输出的头信息
--version 显示版本信息3、执行tcprtat
- 运行 tcpstat 需要 root 权限。
