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).
-h, --help
-
Display help text and exit.
-V, --version
-
Display version and exit.
