Monitor performance using the Oracle Cloud console
Observe and maintain the health of your OCI GoldenGate resources by regularly monitoring metrics, creating alarms, and subscribing to events to keep informed of any abnormal activity among your resources.

Metrics
In the Oracle Cloud console, you can view metrics on the deployment details page and the metrics explorer for any Extracts and Replicats marked as critical. You can also create alarms to stay informed of certain events and take action when needed.
Note:
Ensure that you upgrade your deployment to the latest version to leverage all available metrics. You must also select Critical to deployment health in the OCI GoldenGate deployment console for Extracts and Replicats for which to view metrics.You can view the following OCI GoldenGate metrics in the Oracle Cloud console on the deployment details page and the metrics explorer for Extracts and Replicats marked as critical:
- CPU Utilization: The aggregate of all Oracle Compute Units (OCPUs).
- CPU Consumption: The aggregate number of OCPUs consumed.
- Memory Utilization: The percentage of aggregate memory. Each OCPUs allocates 16 GB memory.
- Deployment Overall Health: The health score of the deployment, which is the aggregate health of the deployment's processes (Administration, Distribution, Receiver, and Performance Metric Services)
- Deployment Inbound Lag: Lag captured for Extracts designated as critical. This metric is the aggregate of all Extracts in the deployment.
- Deployment Outbound Lag: Lag captured for Replicats designated as critical. This metric is the aggregate of all Replicats in the deployment.
- Swap Space Usage: Amount of swap space, in gigabytes, used by the deployment
- Temp Space Usage: Amount of temporary space, in gigabytes, used by the deployment
- File System Usage: Amount of file system space, in gigabytes, used by the deployment
- Extract Status: Health percentage of an Extract process in the deployment.
- Replicat Status: Health percentage of a Replicat process in the deployment.
- DistributionPathStatus: Health percentage of a Distribution Path process in the deployment.
- ReceiverPathStatus: Health percentage of a Receiver Path process in the deployment.
- ExtractLag: Average lag, in seconds, of a Extract process in the deployment.
- ReplicatLag: Average lag, in seconds, of a Replicat process in the deployment.
- DistributionPathLag: Average lag, in seconds, of a Distribution Path process in the deployment.
- ReceiverPathLag: Average lag, in seconds, of a Receiver Path process in the deployment.
- HeartbeatLag: Average lag, in minutes, of a Heartbeat process in the deployment.
Note:
You'll only see metrics for the processes used in your deployment. For example, if you only have an Extract and a Replicat, then you won't see Distribution or Receiver Path metrics.To learn more about about these metrics, see the OCI GoldenGate Metrics reference and Troubleshoot using the Oracle Cloud console.
Learn more about the Oracle Cloud Monitoring.
Create Alarms
For each metric on the Deployment Details page, you can create an alert to inform you when a condition is met. For example, you can create an alarm to notify you when OCPU consumption is less than 50%.
For more information, see Viewing Default Metric Charts.
Subscribe to Events
Events are structured messages that indicate changes in resources. Subscribing to OCI GoldenGate events enable you to keep informed of abnormal activity among your OCI GoldenGate resources, as well as when your deployment reaches its storage limit and when an upgrade is available.
Create rules to subscribe to these events and trigger actions. For
example, a rule might specify goldengate.stateneedsattention
triggers
the Notifications service to send an email to your systems administrator.
For more information, see:
- GoldenGate Events, for the full list of event types that you can create rules for.
- Events Overview, to learn more about events, and how to create rules, and actions.
