Abstract: A method of root cause analysis in a virtual machine environment includes receiving a plurality of events from a system monitoring the virtualized environment. The events may include alarms or alerts, such as alarms or alerts associated with a resource reaching or exceeding a threshold. The capacity manager consumes these events and performs event correlation to produce a set of correlated events. The capacity manager performs a root cause analysis on the set of correlated events to identify one or more root causes. The capacity manager further performs an impact analysis to determine how the root cause impacts the system, such as other virtual machines, hosts or resource in the virtual environment. Based on the root cause and impact analysis, the capacity manager makes one or more recommendations to address issues with or to improve the operations and/or performance of the virtualized environment.

Abstract: The present invention injects and/or removes voice data into and/or out-of an Ethernet stream in a dynamic, Time Division Multiplexer-like manner, thus providing optimum quality Voice with minimal impact on data bandwidth.
