This metric shows the percentage of Space that is used on the ASM Cluster File System. For dismounted ASM Cluster File Systems a value of 0 is returned for this metric.
, This metric generates a warning alert if the space used in the ASM Cluster File System is greater than 85% of the Size of the File System and a critical alert if greater than 97% of the Size of the File system.
The rest of the information in this section is only valid for this metric when it appears in either the Enterprise Manager Grid Control or the Enterprise Manager Database Control (if applicable).
The following table shows how often the metric's value is collected and compared against the default thresholds. The 'Consecutive Number of Occurrences Preceding Notification' column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

The ASM Cluster File System using volume device %ofs_volume_device% is %ofs_used_pct%%% full. Resize the file system to add more space. |
For this metric you can set different warning and critical threshold values for each unique combination of "Volume Device" and "Disk Group" objects.
If warning or critical threshold values are currently set for any unique combination of "Volume Device" and "Disk Group" objects, those thresholds can be viewed on the Metric Detail page for this metric.
To specify or change warning or critical threshold values for each unique combination of "Volume Device" and "Disk Group" objects, use the Edit Thresholds page. See Editing Thresholds for information on accessing the Edit Thresholds page.
This metric is calculated from the columns TOTAL_SIZE and TOTAL_FREE in the V$ASM_FILESYSTEM view. It is calculated as:
TOTAL_SIZE - TOTAL_FREE/TOTAL_SIZE * 100
For dismounted ASM Cluster File Systems, a value of 0 is returned for this metric.
Consider resizing the ASM Cluster File System to add more space to fix the alert generated by this metric.
