Yes, EventSentry monitors the disk utilization by default, this is available in the "Performance System" system health monitoring package. EventSentry monitors Windows performance through the performance counters made available by Windows.
Windows provides a number of performance counters to monitor disk performance, including:
- % Disk Time
- Avg. Disk Bytes / Transfer
- Avg. Disk Queue Length (enabled by default)
- Avg. Disk sec/Transfer
- Disk Transfers/sec
- Split IO/Sec
- Disk Bytes/sec
You can monitor all those counters with EventSentry in any interval, graph the results and setup alerts as well. Our demo shows some examples of performance metrics and how you can access reports: http://demo.eventsentry.com/performancetrends.
Hope this helps.
