Number of IO Operations |
Total number of I/O operations. For this metric, you can set different warning and critical threshold values for each unique combination of "Device Logical Name" and "IO Category" objects. If warning or critical threshold values are currently set for any unique combination of "Device Logical Name" and "IO Category" 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 "Device Logical Name" and "IO Category" objects, use the Edit Thresholds page. See Editing Thresholds for information on accessing the Edit Thresholds page. |
