Resource Usage shows whether your account is hitting the CPU, memory or process limits of your plan. It is the first place to look when a site is slow or intermittently returning errors.
READING IT
- In cPanel open Resource Usage under Metrics.
- Click Details for graphs over time.
- Look at which limit is being hit, and when.
THE LIMITS
- CPU: processing time. Hitting it makes everything slow.
- Physical Memory: RAM. Exceeding it kills processes mid-request, often showing as a 500 error or a white page.
- Entry Processes (EP): simultaneous requests. Hitting this returns 508 Resource Limit Reached to some visitors.
- I/O and IOPS: disk throughput and operations.
INTERPRETING THE PATTERN
A daily spike at a fixed time is usually a backup or cron job. Constant low-level saturation usually means no caching, or an inefficient plugin. Sudden sustained load often means bot traffic or a brute-force attack. Check Metrics > Visitors.
WHAT TO DO
Enable caching, set backups to run weekly at a quiet hour, remove heavy plugins, and block abusive bots. If usage remains high after that, the site has outgrown the plan. Open a ticket and we will recommend the right upgrade.
