Monitoring Bandwidth Usage for a Xen node @ IONCANNON

After my last post on limiting bandwidth usage on a Xen node I thought I would follow up with how to monitor the bandwidth usage of a Xen node. I chose to use netacct-mysql to monitor bandwidth and store the results into a mysql database. This isn't the only way of monitoring the bandwidth but it was easy to set up and stores the information directly into mysql without needing any extra scripts. On the Xen setup I'm using for an example there are 3 nodes and a bucket for each node will be created in the mysql database by netacct. Setting up netacct can be tricky so you will want to check to make sure traffic for each node is going into the correct bucket.

Xen Virtualization: Work with MySQL Server, Ruby on Rails, and Subversion

In this article, Prabhakar Chaganti will show us to create virtual appliances that perform one specific function. These appliances can be web servers, database servers or anything else that you can think of which is useful for your business. The key advantage with these appliances is the fact that they are mostly maintenance free, and can be started up and then used without going through any lengthy installation process. You can use these as needed for your testing and then dispose them off. You can also use them for staging environments or production environments, and you can even share them across the enterprise.
