System monitoring apparatus and method

Abstract

The invention discloses a system monitoring apparatus and a method. The system monitoring apparatus in the embodiment comprises a data collection unit that collects a first data set obtained from the monitored system and judged to represent the state of the system and a second data set obtained from the system; a calculating unit that calculates an index related to the state of the system based on the first data set and the second data set.

Description

technical field [0001] The disclosed embodiments relate to a system monitoring device and method, and more specifically, to a technique for diagnosing and indexing system status. Background technique [0002] With the development of information communication technology, the demand for a service of arranging various types of sensors in buildings and controlling devices in the buildings based on sensor values ​​has greatly increased. The status of systems providing these services can be monitored based on sensor values. Typically, such system monitoring is accompanied by a determination of whether the system is functioning properly or has a defect in the system. [0003] However, existing system monitoring methods are not useful for detecting potential defects in the system. This is because, in general, existing methods merely inform the user that a defect has occurred, and set a defensive threshold to determine that the condition has occurred based on only a small possibili...
