== 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 option, available options: 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.
*-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.
*-V*, *--version*::
Display version information and exit.
*-h*, *--help*::
Display help text 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*::
sort by delta count of interrupts
*n*::
sort by long descriptive name field
*q Q*::
stop updates and exit program
