tcprstat 是一個很不錯的網絡通信檢測，可以支持多種應用協議的處理
安裝
- 安裝
使用了一個fork版本 https://github.com/y123456yz/tcprstat
git clone https://github.com/y123456yz/tcprstat.git
yum -y install bison yacc flex glibc-static libcap-devel
./configure
make && make install
- 支持的命令
./tcprstat --help
tcprstat 0.3.1, libpcap version 1.1.1.
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.
--time <ms>, -T time delay > -T(time) count stastic.
--log <file>, -o if time dealy > -T(time), timestamp record to log file.
--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
%T - counts that package delay time(default 40ms)
%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%C\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.
試用
測試一個redis 服務的
- 安裝redis
yum install -y redis
- 運行命令
./tcprstat -p 6379 -t 1 -n 0
- 運行壓測
redis-benchmark
說明
tcprstat 是一個很不錯的工具，但是目前基本沒看到維護了，實際上bcc是一個更好的性能分析套件，可以放到我們日常的開發以及性能
分析的工具包中
