To monitor CPU and RAM usage in cPanel/WHM, there are several built-in tools and methods, depending on whether you’re using cPanel (user level) or WHM (root/administrator level).
WHM (Web Host Manager) – Root/Admin Access
1. Server Status Tools:
- WHM > Server Status > Server Information
- Shows real-time data on CPU load, memory usage, swap, and processes.
- WHM > Server Status > Daily Process Log
- Displays the top users by CPU and memory usage over the past day.
2. Process Manager:
- WHM > System Health > Process Manager
- Similar to Linux top, lets you see and kill processes using excessive resources
3. Load Averages:
Found on the WHM home page and under “Server Information” — indicates CPU load over 1, 5, and 15 minutes.
4. Install and Use Plugins (Optional):
Tools like Netdata, Munin, or CloudLinux LVE Manager (if installed) provide advanced graphs and resource analytics.
CPanel (User Level)
1. cPanel > Metrics > Resource Usage (if CloudLinux is enabled)
- This shows:
- CPU, memory, I/O usage
- Entry processes and faults
- Historical graphs per day/hour
- Note: This option is only available if your hosting provider uses CloudLinux OS.
2. cPanel > Metrics > Awstats / Analog Stats / Resource Usage Logs
While more focused on web traffic, sometimes you can infer resource strain from traffic spikes.
Command Line (if you have SSH access)
- Use standard Linux tools:
- top / htop – CPU and memory usage
- vmstat – memory statistics
- free -m – current RAM usage
- ps aux –sort=-%mem – memory-hungry processes
