Hi there

A sudden CPU spike on your MySQL server can happen for various reasons, but it usually is one of the following:

A sudden increase in your traffic and user requests can overload the database.
Complex or inefficient queries can consume excessive CPU resources.
Tasks like large data imports or backups can spike CPU usage.

What I would recommend starting with is checking out the following guide here:

https://docs.digitalocean.com/products/databases/mysql/how-to/monitor-databases/

If you observe bottlenecks, look for slow queries in the query statistics on the Logs & Queries page, then use the EXPLAIN statement to explore opportunities for query optimization.

Feel free to share more details here once you’ve gather the information from the above guide.

Heya, @378bf4105b7040f595e3b42bf2f91f

This can happen from several factors. You need to inspect the droplet’s performance and monitor the resource usage to find the source of the problem.

You can also refer to this article as well:

Additionally tools like Prometheus, Grafana, New Relic, or Datadog can provide comprehensive dashboards for CPU, memory, and query performance metrics.
