Log in to your cPanel account, then go to the Metrics section and click on Resource Usage.
Once you open the Resource Usage tool, you’ll get a clear snapshot of your account’s performance – including CPU load, memory (RAM) usage, and active processes.
- When everything is running smoothly, you’ll see a green notification confirming that no issues have been detected.
- If your account is under pressure, the system will highlight warnings and display usage graphs so you can quickly spot where the limits were exceeded.
Below this, you'll see a number of graphs that visually represent resource usage.
Key Resource Metrics in cPanel:
- CPU Usage
You can use up to 100% of a CPU core. Occasional peaks are normal, but if the average stays at the limit, optimization is needed.
- Memory (RAM) Usage
Shows how much RAM your processes are using. High usage isn’t always bad since Linux may cache data to speed things up.
- I/O Usage
Measures how much data your account reads/writes to the server’s storage.
- I/O Operations (IOPS)
Counts how many read/write operations your processes request (like opening files or accessing services).
- Entry Processes
The number of concurrent connections (e.g., opening a web request). Too many can slow down your site.
- Processes
The total number of running processes under your account, including entry processes.
- Faults
Displays errors when limits are exceeded (CPU, Memory, I/O, etc.).
Why Your Website Might Hit Limits
- No Caching: Without a cache plugin, dynamic sites like WordPress put extra load on the server.
- Too Many Plugins: Extra or poorly coded plugins can slow down performance.
- Traffic Spikes: Sudden visits may push resource usage up. Using a CDN like Cloudflare can help.
What To Do if You Exceed Limits
- Update your CMS, plugins, and themes.
- Remove unnecessary plugins or extensions.
- Apply caching and optimization.
- If usage is still high, consider upgrading to VPS or a Dedicated Server.
