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
