Why is it monitoring required?

Why monitoring?

According to the development of enterprises and the improvement of information technology, more and more IT devices, especially servers and network security devices, are available for enterprises and enterprises. From several devices to dozens of hundreds, and so on, the data center is also growing, from a room to a data center on the first floor.
