Graph Description: The Disk I/O detailed graph gives a geometric interpretation of the read, write, flush and seek operations on each physical disk attached to the system at the start of the trace. The X-axis represents time. The Y-axis represents the offset on the physical disk and spans all partitions on that physical disk. The disk I/Os that are presented in the graph are grouped in series by process.
Hovering with the mouse will display tooltips based on the location of the cursor. These tooltips can include:
