1. A system for monitoring a data center comprising: a set of data center resources that provide one or more metrics about their operation; a hierarchy of analyzers configured to process an input of metric data and provide an output of metric data, wherein a first subset from a first level of the hierarchy of analyzers is configured to receive first metric data based on the one or more metrics, and wherein a second subset from another level of the hierarchy of analyzers is configured to receive second metric data output from one or more analyzers from a lower level in the hierarchy of analyzers; a monitoring system configured to: detect a problem based at least in part on an output of an analyzer; correlate a plurality of analyzer outputs based at least in part on the problem; and determine a recommended action based at least in part on the correlated analyzer outputs; and a rendering system configured to transmit display information that highlights the identified problem, the correlated analyzer outputs and the recommended action.
