How to Check Website Overload Causes on cPanel

Website overload can cause slow loading times or even downtime, which negatively impacts user experience. To prevent this, it’s crucial to monitor your website’s resource usage regularly. This practice ensures your site runs efficiently and provides a seamless experience for visitors. When hosting resources exceed their limits, it can lead to performance issues, such as longer loading times or complete service interruptions. 

Keeping track of resource usage helps you identify potential problems before they affect your website’s performance. In this tutorial, we’ll discuss step-by-step instructions to check the causes of a website overload on cPanel.

Check Website Overload Causes cPanel

There are multiple ways to check and fix overloaded website. One commonly used method is through cPanel. To learn more about this method, follow the steps below:

Step 1: Log in to cPanel

Specify the appropriate credentials to log in to your cPanel account:

Step 2: Check Resource Usage

Locate the Resource Usage tool on the cPanel dashboard, usually found under the METRICS tab:

Step 3: Check Resource Usage Status

If no problems are found, as demonstrated below, it means your website is working well within the allowed resources:

However, if the dashboard shows your site was limited in the last 24 hours, it means resource limits were exceeded during that time:

Step 4: Analyze Website Overload cPanel

The resource usage dashboard shows the current stats for resources like CPU, memory, and input/output. It helps you identify where usage is high. Here are the key resources that affect your website’s performance:

• CPU: It shows how much processing power your website uses.
• Memory: It tracks the RAM your site needs to run.
• Inodes: It counts the files and folders in your account.
• Input/Output: It measures the speed of data transfer between your site and the server.

Step 5: Customize Timeframes and Units

You can use the customization options to adjust the timeframe and units displayed. This will help you focus on specific times when resource usage is high. By default, the graphs show resource usage for the day, broken down by hour. To change this, click the Timeframe and Time Unit drop-down menu and choose a different option, like changing the time unit to minutes.

Step 6: Use Snapshots for In-Depth Analysis

Click the Snapshots tab to see detailed snapshots of your website’s activity at specific times. Snapshots show a list of processes that use a lot of resources. The primary details of the snapshots include:

• A process ID represents a unique number for each process.
• The command (CMD) shows the script or command being run.
• CPU usage indicates the percentage of CPU consumed by the process.
• Memory usage refers to the amount of memory the process is using.

Check for processes using a lot of CPU or memory. These could be causing the overload and might need optimization. For example, in the following screenshot, the highlighted process might be the culprit of website overloading: 

Step 7: Check Database and HTTP Queries

The Database Queries tab shows running queries, where long-running or frequent ones may signal inefficiencies that need fixing. On the other hand, the HTTP Queries tab lists requests to your site, and high traffic or large files can strain resources. You can reduce the strain on your server by identifying and addressing slow or repeated queries:

This way, users can check the causes of the website overload on cPanel.

Conclusion

Monitoring your website’s resource usage in cPanel helps you identify potential problems before they impact performance. Identifying high resource consumption, such as CPU or memory usage, and optimizing inefficient processes or queries can help resolve overloads and ensure smooth site operation. You can keep your website fast and reliable by regularly tracking these metrics and making necessary adjustments. In this article, we explained how to use cPanel to check the factors that cause a Website overload.
