Usage

Use this report to see how Service time was consumed by HFS device activity during the observation session. The unexpanded report shows an HFS device, listed by device number, for which activity was observed. If HFS file activity was observed during a sample, but could not be attributed to a specific file and device, the activity is aggregated to a single report line with a device number of “unknown”. You can further expand each line item to show the HFS files associated with the device.
