Linode Network Stats in Cacti

July 16th, 2009 Jon Smith No comments

Linode provides a convenient XML data feed that provides information about your CPU usage and Network Usage. The graph for the CPU Usage seems a little useless, but I have included it here as the XML feed provides the data.

You will need your linode account number to use the graphs, you can find this number by looking at the graphs provided to you in your Linode account management interface. The title of the graph will be “http://www.linode.com/ – yourhostname (linode12345) – CPU – …….”. You will need the text from inside the ( ) for your username ie linode12345.

Cacti Error XML hash version does not exist

June 16th, 2009 Jon Smith No comments

I thought I would write a quick post on this error, it is very simple to fix. If you receive the following error when importing a Cacti Template:

Error: XML: Hash version does not exist

This simply means the template was generated on a version of Cacti newer than the one you are importing to. Don’t despair, there are simple upgrade instructions on the cacti website.

Just make sure you make a full backup of your database and Cacti webfiles before attempting the upgrade (As a cautionary tale, if you installed cacti from a package you should first check to see if an updated package is available. Package installs can sometimes put the different files required in different places)
