SmokePing 是一套相當實用的網路監督工具, 畫出的圖片也很漂亮。雖然要安裝 SmokePing 比較麻煩, 但只要透過 yum 安裝 SmokePing 所需的套件就方便很多了, 以下是 RHEL 及 CentOS 安裝及配置 SmokePing 的方法。

首先啟用 EPEL Repo:

# yum install epel-release

接著安裝 SmokePing 所需的套件:

# yum install perl httpd httpd-devel mod_fcgid rrdtool perl-CGI-SpeedyCGI fping rrdtool-perl perl-Sys-Syslog

然後安裝以下 CPAN 模組:

# yum install perl-CPAN perl-local-lib perl-Time-HiRes

安裝編譯器, 用作編譯 SmokePing 原始碼:

# yum groupinstall “Development tools”

安裝好所需的套件後, 現在到官網下載 SmokePing 原始碼安裝, 目前最新的版本是 2.6.11:

# wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.6.11.tar.gz

解壓縮原始碼:

# tar -zxvf smokeping-2.6.11.tar.gz

安裝 SmokePing 所需的 Perl 模組, 以及編譯 SmokePing:

# cd smokeping-2.6.11/
# ./setup/build-perl-modules.sh
# mkdir /opt/smokeping
# cp -R thirdparty /opt/smokeping/
# ./configure –prefix=/opt/smokeping
# make install

安裝好 SmokePing 後, 現在是配置 SmokePing 的設定檔, 輸入以下指令:

# cd /opt/smokeping/etc<br /><br /> # for foo in *.dist; do cp $foo 'basename $foo .dist'; done

然後開啟 Apache 的設定檔 httpd.conf:

# vi /etc/httpd/conf/httpd.conf

找到設定 DirectoryIndex 的一行, 加入 smokeping.fcgi 及AddHandler 部份, 例如:

DirectoryIndex index.html index.html.var smokeping.fcgi
AddHandler cgi-script .cgi

開啟 /etc/httpd/conf.d/smokeping.conf 檔案, 改成這樣:

<Directory "/var/www/html/smokeping"><br /><br /> Options +ExecCGI<br /><br /> </Directory>

執行以下指令, 建立 SmokePing 儲存資料目錄及設定權限:

# mkdir /opt/smokeping/img
# mkdir /opt/smokeping/data
# mkdir /opt/smokeping/var
# mkdir /opt/smokeping/cache
# chown -R apache:apache /opt/smokeping/img
# chown -R apache:apache /opt/smokeping/cache
# ln -s /opt/smokeping/htdocs /var/www/html/smokeping
# ln -s /opt/smokeping/img /var/www/html/smokeping
# ln -s /opt/smokeping/cache /var/www/html/smokeping
# chmod 600 /opt/smokeping/etc/smokeping_secrets
# chmod 600 /opt/smokeping/etc/smokeping_secrets.dist
# chown -R apache:apache /var/www/html/smokeping

現在建立 SmokePing 的設定檔, 要根據自己的需要修改某些設定:

# vi /opt/smokeping/etc/config

範例檔案:

owner = Sam Tang<br /><br /> contact = you@youremail.com<br /><br /> mailhost = SMTP Server (Ignore if you do not have smtp server)<br /><br /> sendmail = /usr/sbin/sendmail<br /><br /> # NOTE: do not put the Image Cache below cgi-bin<br /><br /> # since all files under cgi-bin will be executed … this is not<br /><br /> # good for images.<br /><br /> imgcache = /opt/smokeping/cache<br /><br /> imgurl = cache<br /><br /> datadir = /opt/smokeping/data<br /><br /> piddir = /opt/smokeping/var<br /><br /> cgiurl = http://some.url/smokeping.cgi<br /><br /> smokemail = /opt/smokeping/etc/smokemail.dist<br /><br /> tmail = /opt/smokeping/etc/tmail.dist<br /><br /> # specify this to get syslog logging<br /><br /> syslogfacility = local0<br /><br /> # each probe is now run in its own process<br /><br /> # disable this to revert to the old behaviour<br /><br /> # concurrentprobes = no</p><br /> <p>*** Alerts ***<br /><br /> to = you@youremail.com<br /><br /> from = from@youremail.com</p><br /> <p>+someloss<br /><br /> type = loss<br /><br /> # in percent<br /><br /> pattern = >0%,*12*,>0%,*12*,>0%<br /><br /> comment = loss 3 times in a row</p><br /> <p>*** Database ***</p><br /> <p>step = 300<br /><br /> pings = 20</p><br /> <p># consfn mrhb steps total</p><br /> <p>AVERAGE 0.5 1 1008<br /><br /> AVERAGE 0.5 12 4320<br /><br /> MIN 0.5 12 4320<br /><br /> MAX 0.5 12 4320<br /><br /> AVERAGE 0.5 144 720<br /><br /> MAX 0.5 144 720<br /><br /> MIN 0.5 144 720</p><br /> <p>*** Presentation ***</p><br /> <p>template = /opt/smokeping/etc/basepage.html.dist</p><br /> <p>+ charts</p><br /> <p>menu = Charts<br /><br /> title = The most interesting destinations</p><br /> <p>++ stddev<br /><br /> sorter = StdDev(entries=>4)<br /><br /> title = Top Standard Deviation<br /><br /> menu = Std Deviation<br /><br /> format = Standard Deviation %f</p><br /> <p>++ max<br /><br /> sorter = Max(entries=>5)<br /><br /> title = Top Max Roundtrip Time<br /><br /> menu = by Max<br /><br /> format = Max Roundtrip Time %f seconds</p><br /> <p>++ loss<br /><br /> sorter = Loss(entries=>5)<br /><br /> title = Top Packet Loss<br /><br /> menu = Loss<br /><br /> format = Packets Lost %f</p><br /> <p>++ median<br /><br /> sorter = Median(entries=>5)<br /><br /> title = Top Median Roundtrip Time<br /><br /> menu = by Median<br /><br /> format = Median RTT %f seconds</p><br /> <p>+ overview</p><br /> <p>width = 600<br /><br /> height = 50<br /><br /> range = 10h</p><br /> <p>+ detail</p><br /> <p>width = 600<br /><br /> height = 200<br /><br /> unison_tolerance = 2</p><br /> <p>"Last 3 Hours" 3h<br /><br /> "Last 30 Hours" 30h<br /><br /> "Last 10 Days" 10d<br /><br /> "Last 400 Days" 400d</p><br /> <p>#+ hierarchies<br /><br /> #++ owner<br /><br /> #title = Host Owner<br /><br /> #++ location<br /><br /> #title = Location</p><br /> <p>*** Probes ***</p><br /> <p>+ FPing</p><br /> <p>binary = /usr/sbin/fping</p><br /> <p>*** Slaves ***<br /><br /> secrets=/opt/smokeping/etc/smokeping_secrets.dist<br /><br /> +boomer<br /><br /> display_name=boomer<br /><br /> color=0000ff</p><br /> <p>+slave2<br /><br /> display_name=another<br /><br /> color=00ff00</p><br /> <p>*** Targets ***</p><br /> <p>probe = FPing</p><br /> <p>menu = Top<br /><br /> title = Network Latency Grapher<br /><br /> remark = Welcome to the SmokePing website of xxx Company. \<br /><br /> Here you will learn all about the latency of our network.</p><br /> <p>+ Server<br /><br /> menu= Localhost</p><br /> <p>++ Google</p><br /> <p>menu = google.com<br /><br /> title = google.com<br /><br /> alerts = someloss<br /><br /> host = www.google.com

然後啟動 httpd:

# systemctl start httpd

設定 SmokePing 開機自動啟動, 需要下載 SmokePing 的開機 script 到 /etc/init.d/ 目錄, 及設定可執行權限:

# cd /etc/init.d/
# wget http://oss.oetiker.ch/smokeping/pub/contrib/smokeping-start-script
# chmod 755 smokeping-start-script

將 smokeping-start-script 第 10 行的 SMOKEPING binary 檔位置, 改成這樣:

SMOKEPING=/usr/local/smokeping/bin/smokeping

最後啟動 SmokePing 便完成了:

# /etc/init.d/smokeping start
