Created attachment 135503 [details] disks wrong throughput SUMMARY Disk throughput B/s not shown correctly in System Monitor STEPS TO REPRODUCE 1. Create a new line chart in System Monitor 2. Data Ranges set to "Automatic Y Data Range" 2. Add Sensors -> Disks -> <a disk> -> Write Rate (B/s) or Read Rate (B/s) OBSERVED RESULT The shown throughput values (text values, y-scale) do not reflect the actual disk throughput. EXPECTED RESULT The values should be correct.
