== 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.
|
|
|
|
*-t*, *--threshold* _min_::
|
|
Only show IRQs with counters above the specified threshold. Human readable values are supported (e.g. 1.2K).
