Monitoring in Globule

Abstract
|
This thesis presents a flexible framework for building complex
monitoring systems. The system architecture is based on the
pipes and filters, allowing one to create a complex monitor from
many smaller components. This allows for great flexibility,
since modifications to the monitor generally affect very few
components. The flexibility of the framework, however, comes at
a cost: it is possible to incorrectly connect components and
create invalid pipelines. As part of the monitoring framework,
we introduce a simple way of validating pipelines based on the
observation that pipelines can be represented as directed
graphs. Finally, this thesis introduces what-if analysis for
Globule. What-if analysis allows an administrator to find the
optimal configuration of a website given a certain traffic,
without modifying the configuration of the actual server. Such
analysis can become a valuable tool for system administrators to
better understand the behavior of a complex system such as
Globule.
