FastConnect Metrics

You can monitor the health, capacity, and performance of your FastConnect connection by using metrics, alarms, and notifications. For more information, see Monitoring Overview and Notifications Overview.

This topic describes the metrics emitted by the metric namespace oci_fastconnect.

Resources: virtual circuits.

Overview of Metrics: oci_fastconnect

The metrics available for your FastConnect virtual circuits help you determine quickly whether your FastConnect connection is up, how much data is flowing over the connection, and whether packets are being dropped for unexpected errors.

Required IAM Policy

To monitor resources, you must be given the required type of access in a An IAM document that specifies who has what type of access to your resources. It is used in different ways: to mean an individual statement written in the policy language; to mean a collection of statements in a single, named "policy" document (which has an Oracle Cloud ID (OCID) assigned to it); and to mean the overall body of policies your organization uses to control access to resources. written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool. The policy must give you access to the monitoring services as well as the resources being monitored. If you try to perform an action and get a message that you don’t have permission or are unauthorized, confirm with your administrator the type of access you've been granted and which A collection of related resources that can be accessed only by certain groups that have been given permission by an administrator in your organization. you should work in. For more information on user authorizations for monitoring, see the Authentication and Authorization section for the related service: Monitoring or Notifications.

Available Metrics: oci_fastconnect

The metrics listed in the following table are automatically available for each virtual circuit in any FastConnect connection that you create. You do not need to enable monitoring on the virtual circuit to get these metrics.

You also can use the Monitoring service to create custom queries.

Each metric includes the following dimensions: 

Currently the only available value is virtualcircuit.
The An Oracle-assigned unique ID called an Oracle Cloud Identifier (OCID). This ID is included as part of the resource's information in both the Console and API. of the virtual circuit.

Connection State

Binary (1 or 0)

The operational state of the virtual circuit's interface. The values are up (1) or down (0). Be aware that the Console uses a large VC icon to indicate the virtual circuit's overall state. That icon's value takes into account the BGP session state, but the ConnectionState metric does not. Therefore the metric can have a value of up (1) while the VC icon's value can be DOWN because the BGP session is down.




Packets Received


Number of packets received on the FastConnect interface at the Oracle end of the connection.


Bytes Received


Number of bytes received on the FastConnect interface at the Oracle end of the connection.


Packets Sent


Number of packets sent from the FastConnect interface at the Oracle end of the connection.


Bytes Sent


Number of bytes sent from the FastConnect interface at the Oracle end of the connection.


Packets with Errors


Number of packets dropped at the Oracle end of the connection. Dropped packets indicate a misconfiguration in some part of the overall system. Check if there's been a change to the configuration of your VCN, the virtual circuit, or your CPE.
