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.

[admin@RB1100test] /system resource> print

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

This submenu shows per-cpu usage, as long as IRQ and Disk usage.

[admin@RB1100test] /system resource cpu> print 
CPU LOAD        IRQ         DISK       
0   5%          0%          0%         
[admin@RB1100test] /system resource cpu> 

Properties

Read-only properties

Property Description
cpu (integer) Identification number of CPU which usage is shown.
load (percent) CPU usage in percents
irq (percent) IRQ usage in percents
disk (percent) Disk usage in percents

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.
  • auto - pick CPU based on number of interrupts. Uses NAPI to optimize interrupts.

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.

[admin@MikroTik] /system resource usb> print detail 
 0 device="2:1" name="RB400 EHCI" serial-number="rb400_usb" vendor-id="0x1d6b" 
   device-id="0x0002" speed="480 Mbps" ports=2 usb-version="2.00" 

 1 device="1:1" name="RB400 OHCI" serial-number="rb400_usb" vendor-id="0x1d6b" 
   device-id="0x0001" speed="12 Mbps" ports=2 usb-version="1.10" 

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

[admin@RB1100test] /system resource pci> print
