===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:
<pre>
[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%
</pre>
<code>"cpu"</code> 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:
<pre>
[admin@x86-test] > /tool profile cpu=all
NAME            CPU        USAGE     
ethernet        1          0%

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:
