US Patent 9276826 Combining multiple signals to determine global system state

Methods and systems are provided for monitoring the health of a service by using a comprehensive collection of analytical values derived from data obtained from a plurality of sensors. Many simultaneous data points are gathered by sensors monitoring a service, which then send the raw data to a collection of analyzers (e.g., servers) running in one or more centralized data centers for examination. Collected data is analyzed to generate various metrics (e.g., analytical values) that can be combined with other data and analysis results to provide indications about the overall health of the service.
