This metric measures the ratio between used database space and total available space, taking into account the following database file metrics:
- current used space
- current size
- maximum size
- free space for each drive where database files are located
The actual available space per drive is calculated first, followed by the sum of the total used space from drives and the total available space from drives. These values are then used to calculate the global percentage.
The metric helps you to maintain control over the database storage area, and monitor database growth in combination with general space management on a database file’s host. If available space decreases or increases because something else in your environment, such as another database, starts or stops taking up space, you may want to analyze this further. You are also alerted when the percentage increases signficantly.Percentage of used/available database space,
