How to Monitor cPanel CPU Usage in Real-Time and Send Alerts to Discord 2025

Are you a system administrator or web hosting provider looking to monitor real-time CPU usage in cPanel and get instant notifications on Discord? This step-by-step guide shows you how to track server CPU usage and send alerts via Discord Webhooks using a simple Bash script and cron jobs.

---

🔧 Prerequisites

Before you begin, ensure you have the following:

• Access to a cPanel server via SSH.
• A Discord server with the ability to create webhooks.
• Basic knowledge of Bash scripting, cron jobs, and Linux command-line tools.
• Required utilities installed on your server: curl, top, awk, grep.

---

🔗 Step 1: Create a Discord Webhook

To send notifications from your server to Discord, you’ll first need a webhook.

1. Open your Discord server.
2. Go to Server Settings > Integrations > Webhooks.
3. Click Create Webhook, set a name and channel.
4. Copy the Webhook URL — you’ll need this for the script.

📝 Step 2: Create a Bash Script to Monitor CPU Usage

We’ll now How to Monitor cPanel CPU Usage in Real-Time and Send Alerts to Discord

1. Create the Script Directory and File

bashCopyEditmkdir -p /home/username/scripts
nano /home/username/scripts/cpu_notification.sh

2. Add the Monitoring Code

Paste the following code into the script file:

bashCopyEdit#!/bin/bash

# cPanel username and server details
cpanel_user="username"  # Replace with your actual cPanel username
cpanel_host="hostmdn.com"  # Replace with your server hostname

# Your Discord webhook URL
webhook_url="https://discord.com/api/webhooks/yourwebhookurl"

# Get current CPU usage percentage
cpu_usage=$(top -bn1 | grep "Cpu(s)" | awk '{print 100 - $8}')
cpu_allocated="100"  # Adjust based on actual CPU quota

# Send data to Discord
curl -X POST -H "Content-Type: application/json" -d @- "$webhook_url" << EOF
{
  "content": "**cPanel CPU Usage Alert** 🚨\nUser: $cpanel_user\nHost: $cpanel_host\nCPU Usage: $cpu_usage%\nCPU Limit: $cpu_allocated%"
}
EOF

3. Save and Exit

Save with Ctrl + X, press Y for yes, then Enter to confirm.

---

🔓 Step 3: Make the Script Executable

bashCopyEditchmod +x /home/username/scripts/cpu_notification.sh

---

🧪 Step 4: Test the Script

Run the script manually to check if it works:

bashCopyEdit/home/username/scripts/cpu_notification.sh

Check your Discord channel — you should receive a message with CPU usage details.

---

⏲️ Step 5: Automate with Cron to Run Every 20 Seconds

To simulate real-time monitoring, schedule the script to run every 20 seconds using cron.

Edit Cron Jobs

bashCopyEditcrontab -e

Add These Lines

bashCopyEdit* * * * * /home/username/scripts/cpu_notification.sh
* * * * * sleep 20; /home/username/scripts/cpu_notification.sh
* * * * * sleep 40; /home/username/scripts/cpu_notification.sh

This setup ensures the script runs three times per minute, every 20 seconds.

---

🧩 Step 6: Extend the Script (Optional)

Want to monitor more than just CPU usage? You can also track:

Memory Usage:

bashCopyEditmemory_usage=$(free -m | awk '/Mem:/ {print $3 "MB used of " $2 "MB"}')

Disk Usage:

bashCopyEditdisk_usage=$(df -h /home | awk 'NR==2 {print $3 " used of " $2}')

Then add them to your Discord payload:

bashCopyEdit"content": "**Resource Usage Alert** 🚨\nCPU: $cpu_usage%\nMemory: $memory_usage\nDisk: $disk_usage"

---

✅ Step 7: Monitor and Verify

After everything is set up:

• Watch your Discord channel for notifications.
• Check /var/log/cron or /var/log/syslog if the messages aren’t showing up.
• Adjust thresholds or notification frequency as needed.

---

🎯 Conclusion

By following this guide, you’ve successfully built a real-time cPanel CPU monitoring system with automated Discord notifications. This setup helps:

• Monitor server resource usage 24/7.
• Get alerts before CPU mysql , spikes affect performance.
• Easily expand to track memory, disk, or other metrics.

📈 Whether you’re managing a shared hosting server or maintaining your own web infrastructure, this lightweight solution keeps you informed and responsive.
