9 | == NAME | |
10 | ||
11 | irqtop - utility to display kernel interrupt information | |
12 | ||
13 | == SYNOPSIS | |
14 | ||
4d297435 | 15 | *irqtop* [options] |
6d5b6948 MB |
16 | |
17 | == DESCRIPTION | |
18 | ||
19 | Display kernel interrupt counter information in *top*(1) style view. | |
20 | ||
21 | 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*. | |
22 | ||
23 | == OPTIONS | |
24 | ||
25 | *-o*, *--output* _list_:: | |
4eab78d3 | 26 | 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_. |
6d5b6948 | 27 | |
17f7caa4 | 28 | *-c*, *--cpu-stat* _mode_:: |
123ba32a | 29 | 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. |
17f7caa4 | 30 | |
4b2fadb1 | 31 | *-C*, *--cpu-list* _list_:: |
32 | Specify cpus in list format to show. | |
33 | ||
6d5b6948 | 34 | *-d*, *--delay* _seconds_:: |
4eab78d3 | 35 | Update interrupt output every _seconds_ intervals. |
6d5b6948 MB |
36 | |
37 | *-s*, *--sort* _column_:: | |
4eab78d3 | 38 | Specify sort criteria by column name. See *--help* output to get column names. The sort criteria may be changes in interactive mode. |
