linux下构建Smokeping网络监控平台

 linux下构建Smokeping网络监控平台

一. Smokeping 简介

1.1 Smokeping简介：

Smokeping 是rrdtool 的作者Tobi Oetiker 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监控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。

1.2 Smokeping 架构组件

Smokeping 有以下组件组成：RRDtool、Fping、Echoping、Curl、Dig、SSh、Perl 模块，Perl、SpeedyCGI、Apache 等。

master/slave 的工作方式，可以在多个节点收集同一个监测点的数据；

二．Smokeping 安装 

2.1 准备工作

[root@smokeping ~]# uname -a

Linux smokeping.junjie.com 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:54 EDT 2009 i686 i686 i386 GNU/Linux

[root@smokeping ~]# cat /etc/redhat-release

Red Hat Enterprise Linux Server release 5.4 (Tikanga)

[root@smokeping ~]# perl -v

This is perl, v5.8.8 built for i386-linux-thread-multi

….

先暂时关闭iptables以及selinux刨除其他影响

构建本地yum数据库

[root@smokeping ~]# cat /etc/yum.repos.d/server.repo

[rhel-server]

name=Red Hat Enterprise Linux server

baseurl=file:///mnt/cdrom/Server/

enabled=1

gpgcheck=1

gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-redhat-release

[rhel-vt]

name=Red Hat Enterprise Linux vt

baseurl=file:///mnt/cdrom/VT/

enabled=1

gpgcheck=1

gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-redhat-release

[rhel-cluster]

name=Red Hat Enterprise Linux cluster

baseurl=file:///mnt/cdrom/Cluster/

enabled=1

gpgcheck=1

gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-redhat-release

[rhel-clusterstorage]

name=Red Hat Enterprise Linux clusterstorage

baseurl=file:///mnt/cdrom/ClusterStorage/

enabled=1

gpgcheck=1

gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-redhat-release

[root@smokeping ~]#

[root@smokeping ~]# mkdir /mnt/cdrom

[root@smokeping ~]# mount /dev/cdrom /mnt/cdrom/

mount: block device /dev/cdrom is write-protected, mounting read-only

[root@smokeping ~]# yum list all

2.2 安装rrdtool

RRDTool 是由Tobias Oetiker 开发的开源软件，它使用RRD（Round Rebin Databases）作为存储格式，Round robin 是一种处理定量数据以及当前元素指针的技术，RRDTool 主要用来跟踪对象的变化情况，生成改对象变化的趋势图。

[root@smokeping ~]# cd /root/smokeping/

[root@smokeping smokeping]# ls

cgilib-0.5.tar.gz

CGI-SpeedyCGI-2.22.tar.gz

echoping-6.0.2.tar.gz

fping.tar.gz

rrdtool-1.4.4.tar.gz

smokeping-2.4.2.tar.gz

# 安装依赖的软件包:

[root@smokeping smokeping]# yum -y install freetype freetype-devel libpng libpng-devel gd gd-devel libxml2 libxml2-devel libiconv libiconv-devel pango pango-devel qpixman qpixman-devel glib glib-devel cairo cairo-devel libart* gettext gettext-devel libjpeg libjpeg-devel perl-XML-Simple.noarch perl-Crypt-SSLeay perl-Digest-HMAC

使rrdtool支持中文

[root@smokeping smokeping]# cat /etc/sysconfig/i18n

LANG="zh_CN.UTF-8"

[root@smokeping smokeping]# export LANG="zh_CN.UTF-8"

[root@smokeping smokeping]# yum -y install fonts-chinese

安装 rrdtool

[root@smokeping smokeping]# tar -zxvf rrdtool-1.4.4.tar.gz -C /usr/local/src/

[root@smokeping smokeping]# cd /usr/local/src/rrdtool-1.4.4/

[root@smokeping rrdtool-1.4.4]# ls

[root@smokeping rrdtool-1.4.4]# sed -i 's/setlocale(LC_NUMERIC, "C")/setlocale(LC_ALL, "zh_CN.UTF-8")/g' src/rrd_graph.c

[root@smokeping rrdtool-1.4.4]# sed -i 's/setlocale(LC_NUMERIC, old_locale)/setlocale(LC_ALL, old_locale)/g' src/rrd_graph.c

[root@smokeping rrdtool-1.4.4]# ./configure --prefix=/usr/local/rrdtool [root@smokeping rrdtool-1.4.4]# make && make install

执行 rrdtool 命令，如果出现以下输出，表示安装成功，并列出了该命令的使用帮助。

[root@smokeping rrdtool-1.4.4]# cd /usr/local/rrdtool/bin/

[root@smokeping CGI-SpeedyCGI-2.22]# perl Makefile.PL

[root@smokeping CGI-SpeedyCGI-2.22]# make

[root@smokeping CGI-SpeedyCGI-2.22]# make install

2.5 安装Perl模块

以下全是 Smokeping 需要的 perl 模块。

[root@smokeping CGI-SpeedyCGI-2.22]# cd

[root@smokeping ~]# yum install -y perl-libwww-perl perl-IO-Socket-SSL perl-Net-Telnet perl-Socket6 perl-Net-DNS perl-LDAP perl-libwww-perl perl-IO-Socket-SSL

2.6 安装Smokeping

[root@smokeping ~]# cd /root/smokeping/

[root@smokeping smokeping]# tar -zxvf smokeping-2.4.2.tar.gz -C /usr/local/src/

[root@smokeping smokeping]#mv /usr/local/src/smokeping-2.4.2/ /usr/local/smokeping

三． Smokeping 初始化配置

3.1修改smokeping相关文件名

在smokeping的子目录中会发现很多“*.dist”命名的文件，这些文件使用的时候请将其改名为“*”并进行配置

[root@smokeping ~]# cd /usr/local/smokeping/

[root@smokeping smokeping]# ls

[root@smokeping smokeping]# cp -a bin/smokeping.dist bin/smokeping

[root@smokeping smokeping]# cp -a htdocs/smokeping.cgi.dist htdocs/smokeping.cgi

[root@smokeping smokeping]# cp -a etc/config.dist etc/config

3.2建立相关目录

接着建立三个目录用于保存smokeping的数据等，如下所示：

[root@smokeping ~]# mkdir /usr/local/smokeping/data

[root@smokeping ~]# mkdir /usr/local/smokeping/var

[root@smokeping ~]# mkdir /usr/local/smokeping/cache

[root@smokeping ~]# yum install -y httpd

[root@smokeping ~]# chown -R apache.apache /usr/local/smokeping

3.3修改配置文件

（1）/usr/local/smokeping/etc/config （somkeping配置基本都在这个文件上）

*** General ***

 

owner    = xjzhujunjie

contact  = [email protected]

mailhost = my.mail.host

sendmail = /usr/lib/sendmail

…

imgcache = /usr/local/smokeping/cache

imgurl   = cache

datadir  = /usr/local/smokeping/data

piddir  = /usr/local/smokeping/var

cgiurl   = http://192.168.101.81/smokeping/smokeping.cgismokemail = /usr/local/smokeping/etc/smokemail.dist

tmail = /usr/local/smokeping/etc/tmail.dist

 

*** Presentation ***

template = /usr/local/smokeping/etc/basepage.html.dist

 

+ charts

+ FPing

binary = /usr/sbin/fping##修改为实际路径

binary = /usr/local/sbin/fping

把#*** Slaves ***下的所有东西注释掉，这里暂时不采用master/slave模式。

#*** Slaves ***

#secrets=/home/oetiker/checkouts/smokeping/trunk/software/etc/smokeping_secrets.dist

#+boomer

#display_name=boomer

#color=0000ff

 

#+slave2

#display_name=another

#color=00ff00

在Targets下添加监控节点，其中Multi也就是在一张图里画多个监测点的数值：

+ Telecom

menu= TeleCom

title = 21ViaNet(China)Telecom

++ xjzhujunjie

menu = xjzhujunjie

title = xjzhujunjie-server

host = 192.168.101.82

++ JiLin

menu = JiLin

title = JiLin_219.149.194.1

host = 219.149.194.1

++ TeleComMulti

menu = TeleMulti

title = 21ViaNet(China) Telecom Network

host = /Telecom/HeiLJ /Telecom/JiLin

（2）/usr/local/smokeping/htdocs/smokeping.cgi注意修改如下内容即可

[root@smokeping ~]# vim /usr/local/smokeping/htdocs/smokeping.cgi

use lib qw(/usr/local/rrdtool/lib/perl);

use lib qw(/usr/local/smokeping/lib);

…

Smokeping::cgi("/usr/local/smokeping/etc/config");

（3）/usr/local/smokeping/bin/smokeping注意修改如下内容即可：

use lib qw(/usr/local/rrdtool/lib/perl);

use lib qw(/usr/local/smokeping/lib);

…

Smokeping::main("/usr/local/smokeping/etc/config");

3.4启动smokeping

（1）编写smokeping启动脚本: 赋予可执行权限，并放在/etc/init.d目录下

[root@smokeping ~]# vim /etc/init.d/smokeping

#!/bin/bash PIDFILE=/usr/local/smokeping/var/smokeping.pid SMOKEPING=/usr/local/smokeping/bin/smokeping ERROR=0 RUNNING=0 ARGV="$@" if [ "x$ARGV" = "x" ] ; then ARGS=help fi for ARG in $@ $ARGS do if [ -f $PIDFILE ] ; then PID=`cat $PIDFILE` if kill -0 $PID 2&gt;/dev/null ; then # smokeping is running RUNNING=1 else # smokeping not running but PID file exists =&gt; delete PID file rm -f $PIDFILE RUNNING=0 fi else # smokeping (no pid file) not running RUNNING=0 fi case $ARG in start) if [ $RUNNING -eq 0 ] ; then if $SMOKEPING &gt; /dev/null; then echo "$0 $ARG: smokeping started" else echo "$0 $ARG: smokeping could not be started" ERROR=1 fi else echo "$0 $ARG: smokeping is running with PID $PID" ERROR=2 fi ;; stop) if [ $RUNNING -eq 1 ] ; then if kill $PID ; then echo "$0 $ARG: smokeping ($PID) stopped" rm $PIDFILE else echo "$0 $ARG: smokeping could not be stopped" ERROR=3 fi else echo "$0 $ARG: smokeping not running" ERROR=4 fi ;; restart) if [ $RUNNING -eq 1 ] ; then if $SMOKEPING --restart &gt; /dev/null; then echo "$0 $ARG: smokeping restarted" else echo "$0 $ARG: smokeping could not be started" ERROR=5 fi else $0 start fi ;; strace_debug) rm -f /tmp/strace_smokeping if [ $RUNNING -eq 1 ] ; then if strace -o/tmp/strace_smokeping $SMOKEPING --restart &gt;/dev/null; then echo "$0 $ARG: smokeping restarted with strace debug in /tmp/strace_smokeping" else echo "$0 $ARG: smokeping strace debug could not be started" ERROR=6 fi else if strace -o/tmp/strace_smokeping $SMOKEPING &gt;/dev/null; then echo "$0 $ARG: smokeping started with strace debug in /tmp/strace_smokeping" else echo "$0 $ARG: smokeping strace debug could not be started" ERROR=7 fi fi ;; status) if [ $RUNNING -eq 1 ] ; then echo "$0 $ARG: smokeping is running with PID ($PID)" else echo "$0 $ARG: smokeping is not running" fi ;; *) echo "usage: $0 (start|stop|restart|status|strace_debug|help)" cat <&lt;EOF start - start smokeping stop - stop smokeping restart - restart smokeping if running or start if not running status - show status if smokeping is running or not help - this screen EOF ;; esac done exit $ERROR

[root@smokeping ~]# chmod +x /etc/init.d/smokeping

[root@smokeping ~]# ll /etc/init.d/smokeping

-rwxr-xr-x 1 root root 2109 Jun 16 16:52 /etc/init.d/smokeping

（2）检查smokeping配置文件:

[root@smokeping ~]# /usr/local/smokeping/bin/smokeping --check

Configuration file '/usr/local/smokeping/etc/config' syntax OK.

（3）启动smokeping:（无法启动）

[root@smokeping ~]# service smokeping start

ERROR: slave 'boomer' is not defined in the '*** Slaves ***' section!

/etc/init.d/smokeping start: smokeping could not be started

 

出现错误à将在后面解决…

 

（4）配置apache  /conf/httpd.conf

[root@smokeping ~]# vim /etc/httpd/conf/httpd.conf

Alias /smokeping/ "/usr/local/smokeping/htdocs/"

Alias /cache/ "/usr/local/smokeping/cache/"

<Directory "/usr/local/smokeping/htdocs">

Options FollowSymLinks ExecCGI

AllowOverride None

AddHandler cgi-script cgi

Order allow,deny

Allow from all

</Directory>

[root@smokeping ~]# service httpd start

Starting httpd: httpd: apr_sockaddr_info_get() failed for smokeping.junjie.com

httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

                                                           [  OK  ]

[root@smokeping ~]#

（ 5 ）测试。 修改完后重启 apache ，在浏览器输入 http://192.168.101.81/smokeping/smokeping.cgi

 

失败。。。待续。。。

3.5 错误排查与测试：

出现错误à将在后面解决…

[root@smokeping ~]# vim /usr/local/smokeping/etc/config

四． Smokeping 的其它配置

4.1 监控节点的增加

[root@smokeping ~]# vim /usr/local/smokeping/etc/config

+ xjzhujunjie

menu = xjzhujunjie

title = xjzhujunjie-server

################web server###############

++ junjie-web

menu = junjie-web

title = xjzhujunjie 网站 192.168.101.82

host = 192.168.101.82

[root@smokeping ~]# service smokeping stop

/etc/init.d/smokeping: line 14: gt: command not found

/etc/init.d/smokeping: line 14: /dev/null: Permission denied

/etc/init.d/smokeping stop: smokeping not running

[root@smokeping ~]# service smokeping start

WARNING: Hostname 'james.address' does currently not resolve to an IPv6 or IPv4 address

/etc/init.d/smokeping start: smokeping started

4.2 报警设置

smokeping 的alert设置有点复杂，但是却很好用，设置很灵活，考虑得很周全。它可以使用邮件进行alert，也可以直接调用外部程序进行IM的报警。在我们的监控中主要是采用邮件报警。报警参数设置如下,哪个节点需要报警增加alerts = manyloss即可

[root@smokeping ~]# vim /usr/local/smokeping/etc/config

*** Alerts ***

to = [email protected]

from = [email protected]

 

+someloss

type = loss

pattern = >0%,*30*,>0%,*30*,>0% # in percent

comment = loss 1 packages in 30 continuous 3 times.

+manyloss

type = loss

pattern = >15%,*30*,>15%,*30*,>15% # in percent

comment = loss 5 packages in 30 continuous 3 times.

+rttbad

type = rtt

pattern = ==S,>50,>50 # in milliseconds

comment = For more than two consecutive 50-millisecond delay.

 

[root@smokeping ~]# service smokeping stop

/etc/init.d/smokeping: line 14: gt: command not found

/etc/init.d/smokeping: line 14: /dev/null: Permission denied

/etc/init.d/smokeping stop: smokeping not running

[root@smokeping ~]# service smokeping start

WARNING: Hostname 'james.address' does currently not resolve to an IPv6 or IPv4 address

/etc/init.d/smokeping start: smokeping started

（1）to 表示接受所有报警的邮箱，如果需要在特定的节点报警发送到特定的邮箱则在该节点上增加alertee = [email protected] 即可。

（2）manyloss 表示30个包丢15%的情况 连续出现3次就发报警。

（3）someloss 表示30个包丢1个，连续出现3次就发送报警；rttbad表示连续两个包延迟超过50ms就发送报警。

4.3 画图设置

Smokeping 默认设置中是每5分钟画一次图，每5分钟发送20个ping包。网络工程师认为5分钟发送20个ping包太少，建议改为5分钟100个。画图的颜色等也要进行相应的更改： 在Database中，step =300 pings =20 改为 step = 300 pings =100

从图上可以看到，slave主机会自己去检查监测点的情况（loss and rtt），并将数值提交给master主机（通过smokeping.cgi)。值得注意的是，slave并不需要config文件，每次slave提交完数据以后，会询问master它自己的配置文件是否有修改，如果有修改的话slave会进行更新。

其它关于smokeping的使用，待续…….

《完》
