Methods for monitoring a networked computing environment and for identifying root causes of performance and availability issues that occur throughout multiple layers of the networked computing environment are described. In some embodiments, a software service provided by a networked computing environment may experience a service-related performance or availability issue. In response to detecting the service-related issue affecting the service, a root cause identification tool may aggregate data from a plurality of information technology management software tools monitoring the networked computing environment, identify causal relationships between a plurality of failures associated with the service-related issue based on the aggregated data, determine a chain of failures of the plurality of failures based on the causal relationships, identify a root cause of the service-related issue based on the chain of failures, and transmit an alarm corresponding with the root cause.
