What causes high CPU utilization in Linux?

More often than not, when you have CPU-bound load, it's due to a process run by a user on the system, such as Apache, MySQL or maybe a shell script. If this percentage is high, a user process such as those is a likely cause of the load.

How do I know if my CPU is bottlenecking Linux?

We can find bottleneck in linux server performance using following method..

  1. Take the output of TOP & mem, vmstat commands in one notepad.
  2. Take sar output of 3 months.
  3. check the variation in processes & usage at the time of implementation or change.
  4. If the load is unusual since the change.

How do I see CPU percentage in Linux?

How is the total CPU usage calculated for a Linux server monitor?

  1. CPU Utilization is calculated using the 'top' command. CPU Utilization = 100 - idle time. Eg:
  2. idle value = 93.1. CPU Utilization = ( 100 - 93.1 ) = 6.9%
  3. If the server is an AWS instance, CPU usage is calculated using the formula: CPU Utilization = 100 - idle_time - steal_time.
