CPU

CPU utlilization (cores)
CPU utlilization (fraction)

Windows: use GetSystemTimes function Linux: read /proc/stat file

Memory

Memory (total)
Memory (available)
Memory (free)
Memory (kernel)
Memory (cached)
Hard page faults per second

Windows: use GetPerformanceInfo function, probably a couple of perf counters Linux: read /proc/meminfo or /proc/vmstat files

Disk space (per volume)

Disk total capacity
Disk free bytes
Disk free percent

This is easy to achieve in managed code with DriveInfo (performance should be tested though).

Disk activity (per device)

Disk idle time percent
Disk operations per second
Disk read/write latency
Disk queue size

TODO: find appropriate sources.

Network

Network received bytes/second
Network sent bytes/second
TCP connections count (total and per TCP state)

This is easy to achieve in managed code with NetworkInterface.GetIPStatistics() and IPGlobalProperties (performance should be tested though).
