IRQTOP(1)                        User Commands                       IRQTOP(1)

NAME
       irqtop - utility to display kernel interrupt information

SYNOPSIS
       irqtop [options]

DESCRIPTION
       Display kernel interrupt counter information in top(1) style view.

       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
       -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.

       -c, --cpu-stat mode
           Show per-cpu statistics by specified mode. Available modes are:
           auto, enable, disable. The default option auto detects the width of
           window, then shows the per-cpu statistics if the width of window is
           large enough to show a full line of statistics.

       -C, --cpu-list list
           Specify cpus in list format to show.

       -d, --delay seconds
           Update interrupt output every seconds intervals.

       -s, --sort column
           Specify sort criteria by column name. See --help output to get
           column names. The sort criteria may be changes in interactive mode.

       -S, --softirq
           Show softirqs information.

       -h, --help
           Display help text and exit.

       -V, --version
           Print version and exit.
