If you're managing or debugging Linux servers, particularly in environments heavily reliant on disk operations like database servers or file servers, monitoring Disk Input/Output (I/O) stats is crucial. An effective tool to help you in this endeavor is iotstat. This utility can provide real-time detailed information about disk I/O by each device, aiding in performance tuning and troubleshooting. In this blog post, I'll introduce you to iotstat, explain its benefits, and guide you through installation via different Linux package managers — namely, apt (for Debian-based distributions), dnf (for Fedora and other RHEL-based distributions), and zypper (for openSUSE/SUSE).
