Smokeping搭建优化

1 什么是smokeping

2 smokeping架构组成

3 smokeping分布式介绍

4 如何看懂smokeping图表

5 如何判断一个节点的好坏

Smokeping是rrdtool的作者TobiOetiker 的作品，是用Perl 写的，主要是监视网络性能，包括常规的ping，用echoping 监www 服务器性能，监视dns 查询性能，监视ssh 性能等。底层也是rrdtool做支持，特点是画的图非常漂亮，网络丢包和延迟用颜色和阴影来表示。

Smokeping由以下组件组成：

RRDtool、Fping、Echoping、Curl、Dig、SSh、Perl 模块，

Perl、SpeedyCGI、ApacheORNGINX

使用Smokeping的过程中，很容易就发现，如果从单个节点去探测网络性能，往往是不够的，Smokeping提供了多节点的分布式部署功能，也就是可以从多个节点去探测到某个地区的网络状态，这样才是我们监控网络希望看到的情况。

Smokeping称其为主从模式，主从模式的配置很简单，从服务器的安装和主服务器相同，只是从服务器不用自己的config文件,而是在启动的过程中请求主服务器的config文件，这样你只需要维护主服务器上的配置文件即可。

Smokeping检测分布式的检测方式是被动模式，由从节点启动时获得主节点的config文件，然后进行测试，测试完毕后直接将数据提交给主节点。主从通信验证是通过我们可以设置多个从服务器，主从服务器通过指定--shared-secret=filename来和主进行密码验证。

X轴表示时间轴

Y轴表示ping的时间值

3.6ms表示 Ping质量测试的响应速度平均值

中间红线能看出网络是否有抖动

直线表示稳定,有频繁曲线表示网络抖动；如果是阴影表示有网络小幅度抖动

ls字段表示Ping质量测试的丢包率

根据网络抖动判断，抖动范围超过10ms的都属于网络不稳定我们要每天观察是否都有规律的网络抖动现象

根据丢包状况判断:

刚进入详细报告后,看总曲线的颜色,根据20个测试数据包返回的数据判断

绿色表示0丢包.属于最好.浅蓝色1个丢包,深蓝色2个丢包….以此类推

从这个报告图里可以看出:

1.曲线都是绿色的0丢包

或偶尔一两个丢包算合格

2.曲线无抖动,阴影不明显

或偶尔有抖动的算合格

(包裹阴影部分)

3.Ping值小于30ms

如果小于50ms还算合格

smokeping搭建

可分多种web框架可选nginx apache等接口可选fsgi cgi

1服务端安装

apache安装略

httpd.conf中directory字段加入

</Directory>
<Directory "/usr/local/smokeping/htdocs">
#Options FollowSymLinks ExecCGI
Options Indexes FollowSymLinks
Options ExecCGI
#AllowOverride None
#Order allow,deny
#Allow from all
</Directory>

Alias /smokeping "/usr/local/smokeping/"
<Directory /usr/local/smokeping/>
   AllowOverride None
   AddHandler cgi-script cgi
   Options ExecCGI
   Options Indexes FollowSymLinks
   Order allow,deny
   Allow from all
   DirectoryIndex smokeping.cgi
</Directory>

1 此处定义节点由于较多所以只写了一个郑州

2 此配置文件针对监控优先级报警采用了3层目录形式可针对自己想监控的节点进行报警，极大降低了误报

3 Alerts定义多种规则，针对不通网络质量采用不通阀值

当然smokeping也支持如RTX 飞信等报警需要手工写一些脚本或添加相应程序实现

目录结构

1 smokeping.cgi 放置在 htdocs下

#!/bin/sh
#export PERL5LIB=/usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/
exec /usr/local/smokeping/bin/smokeping_cgi /usr/local/smokeping/etc/config

让smokeping_cgi读取配置文件执行

2 smokeping生成的cache图片按照定义时间来定义 last_ 后面的数值

3 必须刷新url才可生成cache图片，可定期使用脚本刷新

4 secrets文件权限600

5 smokeping服务端启动脚本

killall -9 smokeping
/usr/local/smokeping/bin/smokeping --config=/usr/local/smokeping/etc/config --logfile=/usr/local/smokeping/htdocs/var/smokeping.log

6 smokeping客户端启动脚本

#!/bin/bash
MASTERURL=http://xxx.xx.xx.xx/htdocs/smokeping.cgi
SLAVENAME=
CACHEDIR=/usr/local/smokeping/cache
PIDFILE=$CACHEDIR/smokeping.pid
SECRET=/usr/local/smokeping/etc/secrets
LOGFILE=/usr/local/smokeping/var/smoke.log

RUNNING=0

if [ -f $PIDFILE ] ; then
PID=`cat $PIDFILE`
if kill -0 $PID 2>/dev/null ; then
   echo "smokeping is running with PID $PID"
   exit 0
else
   echo "smokeping not running but PID file exists => delete PID file"
   rm -f $PIDFILE
fi
else
echo "smokeping (no pid file) not running"
fi

if
/usr/local/smokeping/bin/smokeping --master-url=$MASTERURL --slave-name=$SLAVENAME --cache-dir=$CACHEDIR --shared-secret=$SECRET --logfile=$LOGFILE > /dev/null; then
echo "smokeping started"
else
echo "smokeping could not be started"
fi
