The monitoring of operational functions, commonly referred to as monitoring, can relate to specific operational phases. In predictive monitoring, monitoring is carried out proactively; in real-time monitoring, monitoring is carried out at the time of change; and in reactive monitoring, analyses are only reacted to after a certain period of time.
Real-time monitoring is about continuous monitoring of data updated at short notice. With this technique, it is possible to react quickly to sudden events and changes. Real-time monitoring is used in many technical areas. For example, in network technology for monitoring important network parameters, in the management of data centers, in call centers for call and time control, in online stores for optimizing inventory and sales activities, in vehicle and fleet management, for inventory and theft detection using RFID, in industrial production and general information technology.
Data collected using real-time monitoring is often used for only one application, such as server management. However, the data can come from a variety of sources. For example, in real-time monitoring in networks of switches, routers, firewalls and other components. The data collected in real time can be displayed in tabular form or in a wide variety of diagrams - line graphs, bar charts, pie charts, etc.
