This is a database-level metric. For cluster databases, this metric is monitored at the cluster database target level and not by member instances.
Use the Data Guard Status metric to check the status of each database in the Data Guard configuration.
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.

For this metric you can set different warning and critical threshold values for each "Name" object.
If warning or critical threshold values are currently set for any "Name" object, those thresholds can be viewed on the Metric Detail page for this metric.
To specify or change warning or critical threshold values for each "Name" object, use the Edit Thresholds page. See Editing Thresholds for information on accessing the Edit Thresholds page.
