Manual:System/Resource
Applies to RouterOS: v3, v4 +
Summary
General
Sub-menu level: /system resource
General resource menu shows overall resource usage and router statistics like uptime, memory usage, disk usage, version etc.
It also has several sub-menus for more detailed hardware statistics like PCI, IRQ and USB.

Properties
All properties are read-only
| Property | Description |
|---|---|
| architecture-name (string) | CPU architecture. Can be powerpc, x86, mipsbe or mipsle. |
| bad-blocks (percent) | Shows percentage of bad blocks on the NAND. |
| board-name (string) | RouterBOARD model name |
| cpu (string) | Cpu model that is on the board. |
| cpu-count (integer) | Number of CPUs present on the system. Each core is separate CPU, Intel HT is also separate CPU. |
| cpu-frequency (string) | Current CPU frequency. |
| cpu-load (percent) | Percentage of used CPU resources. Combines all CPUs. Per-core CPU usage can be see in #CPU submenu |
| free-hdd-space (string) | Free space on hard drive or NAND |
| free-memory (string) | Unused amount of RAM |
| platform (string) | Platform name, usually it is "MikroTik" |
| total-hdd-space (string) | Size of the hard drive or NAND |
| total-memory (string) | Amount of installed RAM |
| uptime (time) | Time interval passed since boot-up. |
| version (string) | Installed RouterOS version number. |
| write-sect-since-reboot (integer) | Number of sector writes in HDD or nand since router was last time rebooted. |
| write-sect-total (integer) | Number of sector writes in total. |
CPU
Sub-menu level: /system resource cpu
(needs editing)
Properties
| Property | Description |
|---|---|
| - (string; Default: ) |
IRQ
Sub-menu level: /system resource irq
Menu shows all used IRQs on the router. It is possible to set up IRQ load balancing on mulicore systems by assigning IRQ to specific core.
IRQ assignments are done by hardware and cannot be changed from RouterOS. For example, if all Ethernets are assigned to one IRQ, then you have to deal with hardware: upgrade motherboards BIOS, reassign IRQs manually in BIOS, if none of above helps then change the hardware.
Properties
| Property | Description |
|---|---|
| cpu (auto | integer; Default: ) | Specifies which CPU is assigned to the IRQ.
|
Read-only properties
| Property | Description |
|---|---|
| active-cpu (integer) | Shows active CPU in multicore systems. |
| count (integer) | Number of interrupts. On ethernet interfaces interrupt=packet. |
| irq (integer) | IRQ identification number |
| users (string) | Process assigned to IRQ |
IRQ Load Balancing
RPS
Sub-menu level: /system resource rps
This menu allows to enable Receive Packet Steering (RPS) to reduce single core usage.
NAPI can become a bottleneck under high packet load, because of serialization per device queue. RPS distributes the load of received packet processing across multiple cores.
USB
Sub-menu level: /system resource usb
This menu displays all available USB controllers on the board. Menu is available only if at least one USB controller is present.

Properties
| Property | Description |
|---|---|
| device (string) | |
| device-id (hex) | Hexadecimal device ID |
| name (string) | Descriptive name of the device retrieved from driver |
| ports (integer) | How many ports are supported by usb controller |
| serial-number (string) | |
| speed (string) | Max USB speed that can be used (480Mbps for USBv2 and 12Mbps for USBv1) |
| usb-version (string) | Identifies max spported USB version |
| vendor (string) | Device manufacturer's name. |
| vendor-id (hex) | Hexadecimal vendor ID |
PCI
Sub-menu level: /system resource pci
PCI submenu shows the information about all PCI devices on the board
