CentOS 5.3 Smokeping 2.4.2 Install (quick)

Install the latest smokeping (without distributed polling) on a virgin Centos 5.3 minimal box… It’s probably the best (free) tool for monitoring network latency at a glance.

Examples: Pipe Ten Derby and Pipe Ten Sheffield.

Install all of the smokeping prerequisites:

wget http://dag.wieers.com/rpm/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm
rpm -Uv rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm
rm rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm
yum update
yum install rrdtool perl-CGI-SpeedyCGI fping httpd perl-libwww-perl.noarch fontconfig freetype dejavu-lgc-fonts.noarch

Install and configure smokeping 2.4.2:

wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.4.2.tar.gz
tar xvzf smokeping-2.4.2.tar.gz
mv smokeping-2.4.2 /usr/local/smokeping
chown -R root:root /usr/local/smokeping
cd /usr/local/smokeping/bin
for foo in *.dist; do cp $foo `basename $foo .dist`; done

• comment out or remove everything below “*** Targets ***” > remark (don’t remove probe, menu, title)
• You’ll need to add your targets before you can do anything useful with smokeping.
