Summary
General
/system resource
The 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.

build-time (string) | Installed RouterOS version build-time |
cpu (string) | CPU model that is on the board |
cpu-count (integer) | Number of CPUs present on the system. Each core is a separate CPU, Intel HT is also a 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 seen in CPU submenu |
factory-software (string) | Minimal RouterOS version |
free-hdd-space (string) | Free space on hard drive or NAND |
free-memory (string) | The unused amount of RAM |
platform (string) | Platform name |
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) | A number of sector writes in HDD or NAND since the router was last time rebooted |

CPU
/system resource cpu
This submenu shows per-cpu usage, as long as IRQ and Disk usage.

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
/system resource irq
The menu shows all used IRQs on the router. It is possible to set up IRQ load balancing on multicore systems by assigning IRQ to a 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 the above helps then change the hardware.
Properties
Property | Description |
---|---|
cpu (auto | integer; Default: ) | Specifies which CPU is assigned to the IRQ.
