== NAME

irqtop - utility to display kernel interrupt information

== SYNOPSIS

*irqtop* [options]

*-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
