Operating System Monitoring

For example, lspci can be used to determine the manufacturer, model, and memory size of a system’s video card:

01:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G400 AGP (rev 04) \ (prog-if 00 [VGA])

Subsystem: Matrox Graphics, Inc. Millennium G400 Dual Head Max Flags: medium devsel, IRQ 16

Memory at f4000000 (32-bit, prefetchable) [size=32M]

Memory at fcffc000 (32-bit, non-prefetchable) [size=16K] Memory at fc000000 (32-bit, non-prefetchable) [size=8M]

Expansion ROM at 80000000 [disabled] [size=64K] Capabilities: [dc] Power Management

version 2 Capabilities: [f0] AGP version 2.0

Note:

You can use the lspci command to determine the network card in your system if you do not know the manufacturer or model number.
