# lsirq

## NAME



           lsirq - utility to display kernel interrupt information
    


## SYNOPSIS



           **lsirq**[options]
    


## DESCRIPTION



           Display kernel interrupt counter information.
    
           The default output is subject to change. So whenever possible, you
           should avoid using default outputs in your scripts. Always
           explicitly define expected columns by using **--output**.
    


## OPTIONS



           **-n** , **--noheadings**
               Don’t print headings.
    
           **-i** , **--input** _file_
               Read data from _file_ (Which was created by other tools, e.g.
               sosreport).
    
           **-o** , **--output** _list_
               Specify which output columns to print. Use **--help** to get a
               list of all supported columns. The default list of columns may
               be extended if list is specified in the format _+list_.
    
           **-s** , **--sort** _column_
               Specify sort criteria by column name. See **--help** output to get
               column names.
    
           **-J** , **--json**
               Use JSON output format.
    
           **-P** , **--pairs**
               Produce output in the form of key="value" pairs. All
               potentially unsafe characters are hex-escaped (\x<code>).
    
           **-S** , **--softirq**
               Show softirqs information.
    
           **-t** , **--threshold** _min_
               Only show IRQs with counters above the specified threshold.
               Human readable values are supported (e.g. 1.2K).
    
           **-C** , **--cpu-list** _list_
               Only show interrupt counters on the specified CPU list.
    
           **-h** , **--help**
               Display help text and exit.
