I have an Ubuntu OS server running on AWS. The size is m4.2xlarge (8 Cores and 32 GiB of memory) and the server is not in production yet but it does have abnormal CPU Utilization and varies for no reason. I'm using RunCloud (https://runcloud.io/
) for the server management. The following is a week-long graph on CPU utilization. The peaks is a cron job running so that is as expected but the fact that the CPU utilization varies I can't figure out why. I have already disabled the cron jobs which does not solve this problem. I have run out of ideas to check why I get this abnormal CPU utilization. Can someone help me?
Here is what it looks like right now when using the top command
