## Overview{% #overview %}

Oracle Cloud Infrastructure (OCI) Virtual Cloud Networks (VCNs) are private, flexible data centers in the cloud with security policies and built-in administration and troubleshooting.

This integration allows you to monitor the performance, throughput, and health of your VCNs by collecting metrics and tags from the [`oci_vcn`](https://docs.oracle.com/en-us/iaas/Content/Network/Reference/vnicmetrics.htm#VNIC_Metrics) namespace.

## Setup{% #setup %}

### Installation{% #installation %}

After you set up the [Oracle Cloud Infrastructure](https://docs.datadoghq.com/integrations/oracle_cloud_infrastructure.md) integration, ensure that the `oci_vcn` namespace is included in your [Connector Hub](https://cloud.oracle.com/connector-hub/service-connectors).
