In the server hardware monitoring, the current industry is mainly based on the following two kinds: 1, the server comes with tools, such as HP's Hpacucli,dell OMSA, etc. 2. Intelligent Platform Management interface (IPMI, full name intelligent Platform Management Interface) Based on the above two kinds, through the Nagios, Zabbix or self-research operation and maintenance platform, such as the package, to carry out early warning operations. As the servers used by the company are all Dell

system performance is good.
It is acceptable if the number of active processes per CPU is not greater than 4.
If the number of active processes on each CPU is greater than 5, the system performance problem is serious.
You can also use the vmstat command to determine if our system is too busy. If it is determined that it is very busy, consider whether to change the server or increase the number of CPUs. Summary:
If r is often greater than 3 or 4 and the id is often less than 50, it indicates tha

Each layer-4 switch stores a source IP address that matches the selected server and a connection table associated with the source TCP port. The layer-4 switch then forwards the connection request to the server. All subsequent packets are reinjected and forwarded between the client and the server until the switch discovers a session. When layer-4 switching is used, the access can be connected to a real server to meet user-defined rules, for example, the number of connections on each serv
