OCI NAT Gateways provide outbound internet connectivity observability for private OCI resources.
Use the Oracle Cloud integration to discover and collect metrics against the OCI NAT Gateways.
Setup
To set up the Oracle Cloud integration and discover the OCI NAT Gateways service, do the following:
- Create an Oracle Cloud (OCI) integration if not available in your installed integrations.
- You can select
OCI NAT Gatewaysduring integration or you can edit the existing integration and selectOCI NAT Gateways. - Scan to discover the resources at any time independent of the predefined schedule.
- Once the scan is completed, you can view the OCI NAT Gateways resource under Infrastructure > Resources > Oracle Cloud category.
- Create a template. See Create a Template for more information on how to create a template.
- Refer to Assign a Template on how to assign a template to a resource.
