CMon (C Monitor) is a lightweight HTTP server for remote server operations management. It provides authenticated REST API endpoints to execute system administration commands remotely.
Virtual Memory Arena Allocator (10x to 150x faster than malloc):
- Virtually unlimited allocations via bitmap array instead of single 64-bit integer
- mmap-based virtual memory (up to 64TB theoretical capacity on x86-64)
- Demand paging - physical memory only used when accessed (MMU translates on page fault)
- 512-byte chunks (increased from 256)
- 64 chunks default but configurable to thousands
- Extremely elegant - allocate terabytes virtually, use only what you need
Enhanced Benchmarking:
- Serialized RDTSC for accurate cycle counting (prevents instruction reordering)
- CPU pinning to eliminate scheduling noise
- ARM64 support with virtual counter benchmarks
- 256KB allocations to stress-test large allocations
- Random page touching to destroy locality (realistic workload)
- malloc_trim() to force heap release for fair comparison
Managing remote servers typically requires:
- SSH access and manual command execution
- Custom scripts scattered across systems
- Multiple tools for different operations
- Manual deployment processes
CMon consolidates common server operations into a single authenticated HTTP API, enabling:
- Programmatic server control
- Automated deployment workflows
- Integration with CI/CD pipelines
- Discord/Slack bot integrations
- DevOps automation
