Windows Disk Usage
Wormly Metrics monitors Windows Disk usage - among thousands of other metrics.
A Windows server consuming all the available disk space is of course a serious problem. Wormly monitors the disk utilization level in your Windows servers to ensure that you have sufficient warning to avoid running out of disk space, sending alerts if disk space is running low.
This particular graph is as simple as they come - a trend line showing the disk utilization over a period of time.
It can also be useful for identifing transient space consumption requirements: e.g. A daily database backup procedure might require a large amount of free space to perform a snapshot of the database, before transmitting the backup and deleting the snapshot.
