Abstract: A system provides for display of results from performance data analysis that presents mini-chart overlays on a topology map based on intelligent analytics for components in a I/O data path of a host or other object. The mini-charts may be advantageously used to show criticality of impact to assist a user with incident avoidance and/or to provide fast incident resolution. When launching into the topology map, the user may enable mini-charts and visually see from the charts where a possible performance bottleneck is detected by the analytics. In an embodiment, the mini-charts for the most relevant metrics may be displayed and identified for criticality, such as by color. The colors may be determined by thresholds, that may be set by a user and/or determined by the system, and may be calculated automatically based on learned base line, maximum line and minimum line operations over set times.

Abstract: A system for controlled-tuning path performance data collection through a single application control. In an embodiment, performance data collection may be turned on or off from an application host running a path performance data application via a user interface. The tool may automatically update performance data collection characteristics as the application host I/O data path changes according to user controlled settings but without requiring further user intervention during the updating. In various embodiments, the tool may update continuously and/or at specified intervals. Turning on path performance data collection on the application host via the user interface may automatically set up synchronized performance data collection for all managed objects within I/O data path(s) of the managed objects.

Abstract: An elevator includes a microprocessor-based cab controller mounted on the elevator car to monitor calls for service by passengers in the car, controls the opening and closing of the door, monitors the position of the car relative to an adjacent landing and communicates with a microprocessor-based car controller, disposed at the top of the shaftway, which controls the motion of the car in the shaftway and provides commands to the cab controller, such as door opening and closing demands relating to calls at the landings, and the like. The cab controller monitors the viability of communications which it receives from the car controller, monitors the position of the door relative to the position of the car with respect to floor landings and provides a signal to enable applying power to the sheave-driving motor and the brake pick-up coils in the machine room only in the event that such monitoring indicates no safety problems.
