Monitoring Replication Delays and RPO (BUI)

With asynchronous replication, a time delay occurs when writing data from the source to its replica on the target. A warning and error alert can be set to notify the administrator when a replication delay is approaching or exceeds the replication point objective (RPO). These alerts prompt the administrator to check for networking problems, application problems, and to examine the health of Oracle ZFS Storage Appliance using analytics.

A replication delay alert can be set when creating or editing a replication action. Use the following procedure to set replication delay alerts.

From the Shares menu, select Projects.
Select a project or share, and click the Replication tab.
Next to Actions, click the add icon .
Select the properties for this action. See Replication Action Properties.
Select Recovery point objective and enter a value. Then specify days, hours, minutes, or seconds.
Select Replica lag warning alert and Replica lag error alert, and specify a percentage of the RPO for each property.

Setting these properties will generate warnings at different times. For example, enter 50 to generate a minor alert when the replication delay exceeds 50 percent of the RPO. Enter 180 to generate a major alert when the replication delay exceeds 180 percent of the RPO.

When the replica lag falls below the set values, a minor alert reports the replica lag is within the warning or error limit.
Set an alert action as described in Adding an Alert Action (BUI).
