mpstat
The mpstat utility is a useful tool to monitor CPU utilization, especially with multithreaded applications running on multiprocessor machines, which is a typical configuration for enterprise solutions.
Use mpstat with an argument between 5 seconds to 10 seconds.
An interval that is smaller than 5 or 10 seconds might be more difficult to analyze. A larger interval might provide a means of smoothing the data by removing spikes that could mislead the result.
Output
