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.

       -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.

       -V, --version
           Display version and exit.
