Im running a aws linux 2 EC2 instance and noticed throughout the month there will be sudden spikes in the CPU usage where it gets close to 90% and then drops off. However looking at the average over 2 week periods the average is usually less than 10-20% usage. This randomely happens at night time close to 11:30 PM. Im not running any database on the server as the database is on a RDS SQL. Does anyone know how i can check what it is causing this? I checked my application logs and do see anything specific happening at the time. Any guidance or tips on what or where i can look/
