网络性能监控系统-smokeping

2019独角兽企业重金招聘Python工程师标准>>>

smokeping是一款用来监控网络性能状况的监控软件，我们可以看一下官网关于smokeping的介绍：

SmokePing keeps track of your network latency:

• Best of breed latency visualisation.
• Interactive graph explorer.
• Wide range of latency measurement plugins.
• Master/Slave System for distributed measurement.
• Highly configurable alerting system.
• Live Latency Charts with the most 'interesting' graphs.
• Free and OpenSource Software written in Perl written by Tobi Oetiker, the creator of MRTG and RRDtool

下面介绍smokeping的基本搭建：

0x01 安装其他源

rpm -Uvh  http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm

0x02 安装rrdtool与相关依赖库

yum -y install perl perl-Net-Telnet perl-Net-DNS perl-LDAP perl-libwww-perl perl-RadiusPerl perl-IO-Socket-SSL perl-Socket6 perl-CGI-SpeedyCGI perl-FCGI perl-CGI-SpeedCGI perl-Time-HiRes perl-ExtUtils-MakeMaker perl-RRD-Simple rrdtool rrdtool-perl curl fping echoping httpd httpd-devel gcc make wget libxml2-devel libpng-devel glib pango pango-devel freetype freetype-devel fontconfig cairo cairo-devel libart_lgpl libart_lgpl-devel mod_fastcgi

0x03 下载与安装smokeping

wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.6.10.tar.gz
tar zxvf smokeping-2.6.10.tar.gz
cd smokeping-2.6.10
./configure --prefix=/usr/local/smokeping
./setup/build-perl-modules.sh /usr/local/smokeping/thirdparty (安装Perl module)
./configure --prefix=/usr/local/smokeping
/usr/bin/gmake install

0x04 smokeping相关配置

1)  创建cache、data、var目录、log

cd /usr/local/smokeping
mkdir cache data var
touch /var/log/smokeping.log

2) 授权

chown apache:apache cache data var
chown apache:apache /var/log/smokeping.log

3) 配置文件修改

cd /usr/local/smokeping/htdocs/
mv smokeping.fcgi.dist smokeping.fcgi
cd /usr/local/smokeping/etc
mv config.dist config
vim config
修改ip或域名：cgiurl = http://some.url/smokeping.cgi
修改检测时间：*** Database ***
step = 300
300改为60
修改中文显示：*** Presentation ***
charset = utf-8

4）修改密码文件权限

chmod 600 /usr/local/smokeping/etc/smokeping_secrets.dist

5）修改apache配置，增加权限控制

vim /etc/httpd/conf/httpd.conf
添加如下
Alias /cache "/usr/local/smokeping/cache/"
Alias /cropper "/usr/local/smokeping/htdocs/cropper/"
Alias /smokeping "/usr/local/smokeping/htdocs/smokeping.fcgi"
<Directory "/usr/local/smokeping">
AllowOverride None
Options All
AddHandler cgi-script .fcgi .cgi
AllowOverride AuthConfig
Order allow,deny
Allow from all
AuthName "Smokeping"
AuthType Basic
AuthUserFile /usr/local/smokeping/htdocs/htpasswd
Require valid-user
DirectoryIndex smokeping.fcgi
</Directory>

然后进入cd /usr/local/smokeping/htdocs目录

设置登录账户与密码

htpasswd -c /usr/local/smokeping/htdocs/htpasswd admin

设置登录账户为admin，密码在后面输入，然后重启httpd就可以实现密码验证登录

6）设置开机启动

echo "/usr/local/smokeping/bin/smokeping --logfile=/var/log/smokeping.log 2>&1 &" >> /etc/rc.local

7) 同步系统时间

cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

8) 启动服务

/etc/init.d/httpd start /usr/local/smokeping/bin/smokeping --logfile=/var/log/smokeping.log 2>&1 & 或 /usr/local/smokeping/bin/smokeping &

9) 修改监控内容

+是第一层，++是第二层，后者继承前者，举例如下

+ jiance
menu= xx机房
++ xx-1
menu = ip
title = somename
alerts = someloss
slaves = boomer slave2
host = ip

0x5 smokeping的主从分布式部署方案

替代单一监测点的不足，master/slave的主从模式，一个master可以管理多个slave，多个slave可针对不同的监测点进行网络性能监测。而且slave配置较为简单，slave从master上获取自己的配置信息，检测数据以及web呈现都汇总在master上，slave只负责从master获取的配置信息进行数据检测。smokeping的数据采集是被动式采集，主从之间的通信验证采用类似rsync的密码验证方式，启动服务的用户不必具备root权限，安全性较好。且smokeping占用内存很小，对系统要求不高。

配置要点：

在master的config里修改

*** Slaves ***
secrets=/usr/local/smokeping/etc/smokeping_secrets.dist  #密码文件
+slave1  #"slave1"需要设置为slave主机的hostname，并且写在"slavesecrets.con"文件里面
display_name=slave1

另外，master上面启动"smokeping"进程和apache进程的用户必须要一致。因为rrd文件是由"smokeping"进 程创建的，而数据的update却是由"smokeping.cgi"进行的，也就是apache用户。如果不一致的话会出现rrd文件无法被更新的情况。
