Summary

Command: /tool profile
Standards:


Profiler tool shows CPU usage for each process running in RouterOS. It helps to identify which process is using most of the CPU resources.

CPU usage on multi-core systems

On multi-core systems tool allows to specify per core CPU usage. For example, to view CPU usage on second core use following command:

[admin@x86-test] > /tool profile cpu=2     
NAME             CPU        USAGE       
ethernet         1          0%          
kvm              1          2.5%        
management       1          0.5%        
idle             1          96.5%       
profiling        1          0%          
unclassified     1          0.5% 

"cpu" parameter allows to specify integer number which represents a core or two of predefined values all and total

  • total - this value sets to show sum of all core usages;
  • all - value sets to show cpu usages separately for every available core

Example with both values on two core system:

[admin@x86-test] > /tool profile cpu=all 
NAME             CPU        USAGE       
ethernet         1          0%          
kvm              0          0%          
kvm              1          4.5%        
management       0          0%          
management       1          0.5%        
idle             0          100%        
idle             1          93%         
profiling        0          0%          
profiling        1          2%    

[admin@x86-test] > /tool profile cpu=total 
NAME             CPU        USAGE       
ethernet         all        0%          
console          all        0%          
kvm              all        2.7%        
management       all        0%          
idle             all        97.2%       
profiling        all        0%          
bridging         all        0%  

Tool is also available in winbox:

Classifiers

Profile classifies processes in several classifiers. Most of them are self explanatory and does not require detailed explanation.

  • idle - shows unused CPU. Typically idle=100%-(sum of all process cpu usages).
  • ppp
  • pppoe
  • ppp-compression
  • ppp-mppe
  • ethernet - cpu used by ethernets when sending/receiving packets
  • bridging
  • encrypting - cpu used by packet encryption
  • ipsec - IP security
  • queuing - packet queuing
  • firewall - packet processing in Ip firewall
  • l7-matcher - cpu used by Layer7 matcher.
  • p2p-matcher - Peer-to-peer traffic matcher in ip firewall
  • gre - Gre tunnels
  • eoip - EoIP tunnels
  • m3p - MikroTik Packet Packer Protocol
  • radius
  • ip-pool

  • dns
  • snmp
  • socks
  • web-proxy
  • winbox
  • metarouter-fs
  • metarouter-net
  • kvm
  • profiling - cpu used by Profiler tool itself
  • btest - bandwidth test tool

  • supout.rif - cpu used by supout.rif file creator.
  • management - RouterOS management processes that do not fall into any other classifier. For example, when routes added to kernel, internal messaging exchange between RouterOS applications, etc.
  • unclassified - any other processes that were not classified.
