Visage

Installing Visage dependency Packages

Apt-get install-y build-essential librrd-ruby Ruby Ruby-dev RubyGems

Installing Visage software

Apt-get Install Gemgem Install Visage-app

Start Visage

Visage-app start

Access to Visage-app Web interface after launch

Error Answer:

Start Visage-app Error:

ollectd compile types.rb by default in the folder/share/collectd/folder, copy the Types.rb file to the/usr/share/collectd folder, and set the number of parameters in the collectd.conf configuration file:
typesdb "/usr/share/collectd/types.db"
And then start COLLECTD and Visage-app .

Visage-app data is not collected

Can't see the server on the Visage-app interface? Visage-app boot default is to collect server in folder/var/lib/collectd/rrd folder, but collectd compile installation data by default under/var/lib/collectd/folder. Set the number of references in the collectd.conf configuration file: BaseDir
