前言

上次說到要配合Grafana使用的話，必須要先安裝Somkeping，因為擔心把篇幅拉得太長也沒必要，所以拆開來 (´・ω・`)

如果你是之前沒看到，可以從這邊過去 將Somkeping整合進Grafana呈現

如果覺得麻煩，這邊也有自動安裝的腳本可以使用 こっち

進入正題

以下由Centos 7為範例

1
yum install epel-release

. 接著安裝smokeping 所需的套件：

1
yum -y install perl httpd httpd-devel mod_fcgid rrdtool perl-CGI-SpeedyCGI fping rrdtool-perl perl-Sys-Syslog gcc gcc-c++ libxml* pango*  freetype-devel zlib-devel libpng-devel libart_lgpl-devel apr-util-devel apr-devel

. 安裝rrdtool

1
yum -y install libart_lgpl-devel zlib-devel libpng-devel freetype-devel  cairo-devel libxml2-devel pango-devel dejavu-lgc-fonts* pango* freetype* rrdtool-perl

※中文顯示有問題，則安裝wqy套件

1
yum -y install wqy*

. 安裝CPAN模組：

1
yum -y install perl-CPAN perl-local-lib perl-Time-HiRes

. 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:

1
wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.6.11.tar.gz

. 解壓縮原始碼:

1
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/
./configure --prefix=/usr/local/smokeping
./setup/build-perl-modules.sh /usr/local/smokeping/thirdparty

wget http://fping.org/dist/fping-3.10.tar.gz
tar -zxvf fping-3.10.tar.gz
cd fping-3.10
./configure
make && make install

. 確認Fping的位置

可能出現的例外錯誤

  1. 如果出現Apache 403 Forbidden

在conf中加入

Require All granted

TCP Ping 的BUG修改

經過大排長龍的設定後，自此Smokeping就安裝完成啦~但你會發現Tcpping的時候資料很奇怪，是因為tcptraceroute呈現改變了，因此要以下調整：

vim /usr/bin/tcpping

1
2
3
4
5
6
7
8
ttr=`tcptraceroute -f ${ttl} -m ${ttl} -q ${q} -w ${w} $*  2>&1` 
改成
ttr=`tcptraceroute -f ${ttl} -m ${ttl} -q ${q} -w ${w} $* |grep -v traceroute 2>&1`
 
  
ttr=`tcptraceroute -f ${ttl} -m ${ttl} -q ${q} -w ${w} $*  2>/dev/null`
改成
ttr=`tcptraceroute -f ${ttl} -m ${ttl} -q ${q} -w ${w} $* |grep -v traceroute 2>/dev/null`

第二個 bug

為甚麼延遲都是255，上網查了之後這是smokeping的BUG。

你用tcpping -C -x 1 www.google.com 80 永遠都是255。

照着如下修改：

vi /usr/bin/tcpping

1
2
3
rtt=`echo "${ttr}" | sed 's/.*] //' | awk '{print $1}'`
改成
rtt=`echo "${ttr}" | sed 's/.*] //' | awk '{print $5}'`

修改完後再重啟smokeping就完成了。
