System Monitoring Not Available

+

+ System monitoring is not available in serverless environments like Cloudflare Pages, Netlify, or Vercel. These + platforms don't provide access to the underlying system resources. +

+
+

+ Why is this disabled? +
+ Serverless platforms execute your code in isolated environments without access to the server's operating + system metrics like CPU, memory, and disk usage. +

+

+ System monitoring features will be available when running in: +

    +
  • Local development environment
    • +
  • Virtual Machines (VMs)
    • +
  • Dedicated servers
    • +
  • Docker containers (with proper permissions)
