Identify the current state of the system
Model of the system server
CPU the speed and quantity of
Memory size
I/O Equipment Situation
Network status
Number of system users and number of concurrent users
Current system CPU usage, Memory utilization
currently I/O the state of the system (average read-write response time, I/O wait time, etc.)
So how do you get the information you need? For the model of the system server, the speed of the CPU, and the amount and memory size, this is very easy to know. The following are descriptions of how I/O devices, network conditions, number of system users, number of concurrent users, current system CPU usage, memory usage, current I/O system status (average read and write response time, I/O wait time) are obtained in the window System and Linux operating system.
