Visage is a web interface for viewing collectd statistics.
It also provides a JSON interface onto collectd's RRDs, giving you an easy way to mash up the data.
First, some dependencies…
apt-get install -y build-essential librrd-ruby ruby ruby-dev rubygems collectd
yum install -y ruby-RRDtool ruby rubygems collectd
Hey wait a sec! I use CentOS/RHEL!
Then install Visage:
gem install visage-app
Now, to start Visage:
That didn't work? Try this.
$(dirname $(dirname $(gem which visage-app)))/bin/visage-app start
