Hi, Not sure if you found the answer to this. I was looking for the same this week and I found it. you need to use Server metrics (not Dabase Metrics) since this is server volume\disk related. When looking into documentation, I found this. Please read the description for <partition> Avg read time (ms) and <partition> Avg write time (ms). You will see that that's exactly what you are looking for. You can navigate to it in the metric browser, path should something like: Application Infrastructure Performance|Root|<ApplicationName>|SQL|Individual Nodes|<NodeName>-java-MA|Hardware Resources|Disks|<partition>-|Avg read time (ms). Also, as an additional note, if you wish to add that to a dashboard, you will need to specify the path as it doesn't show when selecting from the metrics, you need to provide the path starting from Hardware Resources, i.e.: Hardware Resources|Disks|<partition>-|Avg read time (ms). you will see values appear in the dashboard.  Hope the above helps.- ...
