Abstract: Some implementations relate to methods, systems, and computer-readable media for detection and monitoring of available uptime which measures both how accessible a computer system is and how well it is functioning. In some implementations, a computer-implemented method includes determining a number of health check ping responses to a health check ping that are received from a computer system during an allotted timeframe, determining a number of non-error responses measured by the computer system during the allotted timeframe, aggregating the number of health check ping responses and the number of non-error responses to determine a number of partially to fully functioning periods associated with the computer system over a larger time interval, and outputting a system health metric based upon overall functionality of the system over the larger time interval.
