iostat is a command-line utility used to monitor system input/output device loading by observing the time devices are active compared to their average transfer rates. It provides useful insights into system performance, especially for identifying I/O bottlenecks.

Features of iostat:

  • Displays CPU utilization statistics and I/O statistics for devices.
  • Helps identify performance bottlenecks related to disk I/O.
  • Supports monitoring of both local and remote disks.
  • Provides historical data and real-time performance metrics.
  • Can be used in scripts to automate monitoring tasks.

To check the version of iostat, use the following command:

iostat -V

To view device I/O statistics:

iostat -d

To view CPU statistics:

iostat -c

Disclaimer: iostat is a standard utility included in many Unix-like operating systems and is provided "as is." It is a tool for monitoring system performance and should be used as part of a broader performance analysis strategy. The utility does not provide real-time alerts or automated responses and should be used with other tools for comprehensive monitoring and management.
