IRQTOP(1)                     User Commands                    IRQTOP(1)

NAME top

       irqtop - utility to display kernel interrupt information

SYNOPSIS top

       irqtop [options]

DESCRIPTION top

       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 top

       -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.

INTERACTIVE MODE KEY COMMANDS top

       i
           sort by short irq name or number field

       t
           sort by total count of interrupts (the default)

       d
           sort by delta count of interrupts

       n
           sort by long descriptive name field

       q Q
           stop updates and exit program
