How to diagnose high CPU, memory, or disk usage Print

Performance issues are usually caused by a small number of busy processes or exhausted resources.

• Use top or htop to identify high CPU and memory usage.
• Use free -h to check available memory and swap usage.
• Use df -h to check filesystem capacity.
• Use du -sh /path/* to locate large directories.
• Use journalctl -xe or application logs to look for repeated errors.

If you contact support, include the command output and the time period when the problem occurred.
