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.
INTERACTIVE MODE KEY COMMANDS
i
sort by short irq name or number field
t
sort by total count of interrupts (the default)
d

n
sort by long descriptive name field

stop updates and exit program
