March 31, 20215 yr Is there a good visual/graphical way to monitor disk usage on an unRAID server, something along the lines of the Resource Monitor "Disk" tab in Windows? I find out sometimes (when writing lots of smaller files) even disk speed usage is very low (such as 20MB/s), but the disk still works very hard. The windows disk manager will show me the read speed is 20MB/S, but disk usage is 100%, then I know the disk is bottleneck my operation.
December 3, 20223 yr Hi there, I was about to ask the exact same question that JeffSuperb had already asked here. I find the answer to be missing the point of the question. Jeff and I are not trying to find the current read/write speed of the disks, but instead trying to find the "active time" (referring to jeffs windows task manager picture). If the active time is 100%, we know that the HDD in question is working as fast as it can. This would help identify SMR disk write problems or multidisk operation bottlenecks.
December 3, 20223 yr Not sure I my previous answer was answering perfectly the OP's question or not. Regarding your question @Astire : to my knowledge, there is nothing built-in that would monitor disk activity over time. You might have that kind information with the docker container Netdata.
