iostat: Display extended disk statistics with disk names for device "sda".
$ iostat -xN ${sda}
try on your machine
The command "iostat -xN ${sda}" is used to display input/output statistics for devices in a Linux system. The specific breakdown of the command is as follows:
- "iostat" is the command itself. It stands for "Input/Output statistics" and is used to monitor system I/O performance.
- "-x" is an option that tells iostat to display extended statistics. This provides more detailed information about each device.
- "-N" is also an option used to specify the name of the device to display statistics for. In this case, "${sda}" is a variable that represents the device name. The actual device name can be replaced with any specific device identifier, such as sda, sdb, or nvme0n1 depending on the system configuration.
By running this command, you can see the I/O statistics for the specified device, including metrics like the number of read/write operations, transfer rates, and CPU utilization related to the device.
