Manual:Tools/Profiler

Applies to RouterOS: v5beta7 +

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
• radius
• ip-pool
• routing
• sniffing
• traffic-accounting
• traffic-flow
• console
• telnet
• ssh
• ftp
• tfpt
• www
• dns
• snmp
• socks
• web-proxy
• winbox
• metarouter-fs
• metarouter-net
• kvm
• profiling - cpu used by Profiler tool itself
• btest - bandwidth test tool
• logging
• flash - cpu usage when writing to NAND
• disk - cpu usage when wiring to Disk
• serial
• usb
• firewall-mgmt
• queue-mgmt

• user-manager
• wireless
• dude
• 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.
