Determining whether a Grid is up in the face of complex Grid software deployments can be difficult and depends on the types of applications and users that utilize it. By detailing a set of software, services, and features that should be available on a Grid in a machine-readable format, a Grid can be tested periodically by an automated system to verify its health and usability to users. To this end, we have developed Inca as a flexible framework to perform periodic, user-level functionality testing and performance measurement of Grid systems. It includes mechanisms to schedule the execution of information gathering scripts, and to collect, archive, publish, and display data
The architecture of Inca and a description of its components is shown in the below figures.
