I am trying to find process execution information with powershell ps. 
There is an attribute 'SI' whose values are usually like 0, 2, 10, etc. 
Specifically, I typed in the following to powershell: 

```
    PS C:\Users\> ps -pid 10860

Handles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName                                                  
-------  ------    -----      -----     ------     --  -- -----------                                                  
    175      12    23068      12276       0.20  10860   2 geckodriver

```

Thanks!
There is no code.  

I could not find documentation for this SI attribute. 
Can anyone help ? 
Thanks
