cpu monitoring software

The shell monitors cpu,memory,load average, logs to log, and notifies the administrator when the load is under pressure.Implementation principle:1. Get the value of Cpu,memory,load average2. Determine if the value exceeds the custom range, for example (Cpu>90%,memory3. If the value exceeds the range, send an email to notify the administrator. It is sent at a time
