I’m pleased to announce oneInsight, a visualization addon for OpenNebula that allows users to have at-a-glance, an insight of the load of managed hosts. It provides various kinds of load mappings, that currently include the following metrics:

• CPU used by OpenNebula-managed virtual machines;
• Memory used by managed virtual machines;
• Effective CPU used by all system processes, including processes outside of managed virtual machines;
• Effective memory used by all system processes.

Here is a screenshot showing an overview of CPU used.

Benefits

oneInsight enables many benefits, as well for cloud operators than for business managers:

• Provides a simple and comprehensible load charting that allows you to have at-a-glance an accurate insight on how servers are loaded, so to let you plan migrations and capacity upgrading if necessary;
• Provides, via tooltip and popup, details about each server in zero or one click;
• High class visualization that saves you from command line output;
• Lightweight HTML/Javascript stack that can be deployed on any server within your IT infrastructure, just need a valid OpenNebula user account and a network access to OpenNebula server.

How oneInsight Works

oneInsight works out-of-the-box on the vast majority of Linux operating systems, subject to have the following tools installed:

• curl command line interface
• The Bash interpreter
• The cron time-based job scheduler
• A Web server like Apache and nginx, even the python SimpleHTTPServer module just works fine
