If your website is experiencing slow loading times, it may be due to resource overload. Consequently, a website becomes overloaded when hosting resources exceed their allocated limits. This guide can help you easily identify the cause of website overload issues in cPanel.

Proceed with the following steps:

1. Access Resource Usage:
   1.  Log in to your cPanel account.
   2. Navigate to the Metrics section and click on Resource Usage.
      
   3. Alternatively, use the search bar to find the Resource Usage option.
   4. Once inside the Resource Usage Dashboard, you will see an overview of your hosting resources:
      1. No Issues Detected – Your website is optimized and functioning within resource limits.
      2. Limited Usage in the Past 24 Hours – Your website has exceeded resource limits, leading to overload.
      3. Approaching Resource Limits – Your site is close to exceeding its allocated resources, potentially leading to performance issues.
         
2.  Analyse Resource Usage Details:
   To identify excessive usage:

    

   1. Click on the Details button or go to the Current Usage tab.
   2. Review detailed resource usage metrics for Memory, CPU, Inodes, and Input/Output.
      
   3. Graphs display resource usage per hour by default. To adjust the view:
      1. Click on the Timeframe drop-down menu.
      2. Similarly, change the Time Unit setting (e.g., from hours to minutes) for a more granular analysis.
         
3.  Examine Snapshots:
   To pinpoint the cause of website overload:

    

   1. Click on the Snapshot tab.
      
   2. Review the list of running processes within the selected timeframe.
   3. The process list includes:
      1. PID – Process ID
      2. CMD – Process name
      3. CPU – CPU usage percentage
      4. MEM – Memory consumption
   4. For example, if a process like script.php consumes 103% CPU, it undeniably indicates excessive CPU load, leading to slow performance.
   5. To check resource overload on a different date:
      1. Click on the date selector.
      2. If available, use the Choose Snapshot option to review data from a specific time. Consequently, this helps in identifying trends or issues more effectively.
   6. Furthermore, explore the Database Queries and HTTP Queries tabs to identify potential issues related to database or web server requests.

By following these steps, you can effectively diagnose and manage website overload issues in cPanel, ensuring optimal performance and resource utilisation.
