To diagnose disk performance bottlenecks on Linux, analyze per-device disk I/O statistics including throughput, IOPS, and latency metrics. Examining metrics like await and %util helps pinpoint saturated storage devices causing slow system responsiveness.
The await metric indicates the average time spent waiting for disk I/O requests, while %util shows the percentage of CPU time during which I/O requests were issued. High values in both metrics help identify saturated devices slowing down your system.
You can get extended disk throughput and IOPS statistics by running iostat with extended statistics and human-readable output. Configuring continuous updates every second allows you to actively monitor read/write operations and disk performance.
Yes, you need the sysstat package installed to execute iostat commands for monitoring per-device disk statistics. This package provides the required utilities to generate detailed CPU usage and disk I/O reports in Linux environments.
Slow application response times often occur when disk I/O becomes a bottleneck. Check if disk performance is the issue by examining await and %util metrics to identify high I/O queue depths or saturated storage devices.
