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
