You can monitor the health, capacity, and performance of your Oracle Cloud Infrastructure resources by using metrics, alarms, and notifications. For more information, see Monitoring Overview and Notifications Overview.
There are multiple Monitoring service metric namespaces related to networking resources.
For instance connectivity:
- oci_vcn: Metrics related to A VNIC enables an instance to connect to a VCN and determines how the instance connects with endpoints inside and outside the VCN. Each instance automatically comes with a primary VNIC, and you can add secondary ones. Other types of cloud resources also automatically get a VNIC upon creation (examples: load balancers, DB systems).. See VNIC Metrics.
For cloud connectivity:
- oci_fastconnect: Metrics related to FastConnect provides an easy way to create a dedicated, private connection between your data center or existing network and Oracle Cloud Infrastructure. FastConnect provides higher-bandwidth options, and a more reliable and consistent networking experience compared to internet-based connections.. See FastConnect Metrics.
- oci_vpn: Metrics related to an The secure connection between a dynamic routing gateway (DRG) and customer-premises equipment (CPE), consisting of multiple IPSec tunnels. The IPSec connection is one of the components forming a site-to-site VPN between a virtual cloud network (VCN) and your on-premises network.. See VPN Connect Metrics.
