Resource Usage & Limits

Monitor and optimize your hosting resource consumption for optimal performance.

Understanding Shared Hosting Resources

Shared hosting means your website shares server resources with other users. While this keeps costs low, it means resources are allocated fairly to ensure all sites perform well.

Key Resources:

• CPU: Processing power for scripts
• Memory (RAM): Active process storage
• Disk Space: File and database storage
• Bandwidth: Data transfer to/from site

• Inodes: File and directory count
• I/O Operations: Disk read/write speed
• Entry Processes: Concurrent PHP scripts

Checking Resource Usage in cPanel

Method 1: Statistics Sidebar

Log in to cPanel and look at the left or right sidebar for quick stats: disk usage, bandwidth usage, email accounts, and databases.

Method 2: CPU and Connection Usage

Go to Metrics → CPU and Concurrent Connection Usage to view detailed graphs:

• CPU usage percentage
• Physical memory
• Virtual memory
• Entry processes
• Number of processes
• I/O usage

Method 3: Resource Usage Interface

Look for "Resource Usage" in cPanel to view comprehensive statistics, see limits and current usage, and identify resource-intensive periods.

CPU Usage

CPU (Central Processing Unit) is the "brain" that executes your scripts.

What Consumes CPU:

• PHP scripts execution
• Database queries
• Image processing
• Complex calculations
• Search functionality

Signs of High CPU Usage:

• Slow page loading
• Timeouts
• "508 Resource Limit Reached" errors
• Warnings from hosting provider

Memory (RAM)

Memory is temporary storage used while scripts run.

What Consumes Memory:

• Running PHP scripts
• Database connections
• Caching systems
• Image manipulation
• Large file processing

Memory Issues:

• "Allowed memory size exhausted" errors
• White screen of death
• Incomplete page loads

Disk Space

What Uses Disk Space:

• Website files (HTML, CSS, JS, images)
• Databases
• Email messages and attachments
• Backups
• Log files
• Temporary files

Checking Disk Usage:

• cPanel sidebar shows total usage
• File Manager shows size of directories
• Disk Usage tool (Metrics) shows breakdown

Bandwidth

Data transferred to and from your site.

What Consumes Bandwidth:

• Page views (HTML, CSS, JavaScript)
• Image downloads
• Video streaming
• File downloads
• Email (SMTP/IMAP/POP3)
• FTP uploads/downloads

Checking Bandwidth:

• cPanel → Metrics → Bandwidth
• View current month's usage
• See breakdown by protocol
• View historical trends

Inodes

Inodes represent the number of files and folders. Each file and directory = 1 inode.

Common Inode Limits:

• Entry plans: 50,000 - 100,000
• Standard plans: 250,000 - 500,000
• Reaching limit prevents creating new files

High Inode Usage Causes:

• Email accounts with thousands of messages
• Backup files not cleaned up
• Cache directories with many files
• Log files

Resource Limit Errors

508 Resource Limit Reached

508 Resource Limit Is Reached
The website is temporarily unable to service your request as it exceeded resource limit.

Solutions:

• Check Resource Usage in cPanel to identify bottleneck
• Optimize code and database queries
• Implement caching
• Upgrade hosting plan if consistent

Disk Quota Exceeded

Error: Disk quota exceeded

Immediate Actions:

• Delete unnecessary files
• Clear email accounts
• Remove old backups
• Clean up log files

Memory Exhausted

Fatal error: Allowed memory size of 134217728 bytes exhausted
