WatchTower is a cloud server monitoring and management tool
WatchTower is a cloud server monitoring and management tool. This is actually a suite of tools that includes a dashboard and associated RESTful web services required for managing the servers and services. The dashboard uses PHP/MySQL (requires php5+), html, and css. It's all open source and very easy to work with and make changes. The client I'm using is included and is written in python. Currently tested with Python 2.4 and 2.6, but should work with any version.
OpenECP is an open source fork of the Enomaly Elastic Computing Platform (ECP) following its commercialisation. It is a web-based management platform for hypervisors which can be used to create "public" and "private" cloud computing environments.
Freenomalism is a free, community based fork of the Enomalism web-based virtual infrastructure/cloud computing platform. The dashboard can help with issues including deployment planning, load balancing, migration, configuration management, and capacity.
