NAME
dstat - versatile tool for generating system resource statistics
SYNOPSIS
dstat [-afv] [options..] [delay [count]]
DESCRIPTION
Dstat is a versatile replacement for vmstat, iostat and ifstat. Dstat overcomes some of the limitations and adds some extra features.
Dstat allows you to view all of your system resources instantly, you can eg. compare disk usage in combination with interrupts from
your IDE controller, or compare the network bandwidth numbers directly with the disk throughput (in the same interval).
Dstat also cleverly gives you the most detailed information in columns and clearly indicates in what magnitude and unit the output is
displayed. Less confusion, less mistakes, more efficient.
Dstat is unique in letting you aggregate block device throughput for a certain diskset or network bandwidth for a group of interfaces,
ie. you can see the throughput for all the block devices that make up a single filesystem or storage system.
Dstat allows its data to be directly written to a CSV file to be imported and used by OpenOffice, Gnumeric or Excel to create graphs.
Note
Users of Sleuthkit might find Sleuthkit?셲 dstat being renamed to datastat to avoid a name conflict. See Debian bug #283709 for more
information.
