Datadog’s OCI QuickStart is a fully managed, single-flow setup experience that helps you monitor your OCI infrastructure and applications in just a few clicks. OCI QuickStart creates the necessary infrastructure for forwarding metrics, logs, and resource data to Datadog, and automatically discovers new resources or OCI compartments for data collection.

Note: Only metrics are sent by default. Enable log collection and resource data collection from the Datadog OCI integration tile after completing this setup.

To set up the infrastructure for metric and log forwarding to Datadog:

• Configure the Datadog OCI integration tile
• Deploy the QuickStart stack
• Complete the setup in Datadog
• Validate metrics are flowing
• Configure metric collection (optional)
• Configure log collection (optional)

The integration requires using Oracle Service Connector Hubs to forward data to Datadog. It is recommended that you request a service limit increase before completing the setup. The approximate number of Service Connector Hubs you need is:

$$\text"Service Connector Hubs" = \text"Number of compartments in tenancy" / \text"5"$$

Datadog OCI integration tile

1. Go to the Datadog OCI integration tile and click Add New Tenancy.
2. Select or create a Datadog API key to use for the integration.
3. Create a Datadog application key.
4. Click Create OCI Stack. This takes you to an Oracle Resource Manager (ORM) stack to finish deployment.
   Note: Deploy this stack only once per tenancy.

ORM stack

1. Accept the Oracle Terms of Use.
2. Leave the option to use custom Terraform providers unchecked.
3. Use the default working directory to deploy the stack in, or optionally choose a different one.
4. Click Next, and Next again.
   
5. Click Create, and wait up to 15 minutes for the deployment to complete.

To forward your OCI metrics to Datadog:

• Enter tenancy info
• Deploy OCI policy stack in the home region of your tenancy to create a Datadog read-only user, group, and policies
• Enter DatadogROAuthUser info in Datadog
• Deploy OCI metric forwarding stack for every tenancy region you want to forward metrics from
• Complete the setup in Datadog
• Validate metrics are flowing
• Configure metric collection (optional)
• Configure log collection (optional)

For a visual representation of this architecture, see the Architecture section.

Enter tenancy info

Enter the OCID and home region of the tenancy you want to monitor in the Datadog OCI integration tile.

• You can find this information on the Tenancy details page.
• Enter the home region using the Region Identifier value from the OCI Regions and Availability Domains page.

Create OCI policy stack

This Oracle Resource Manager (ORM) policy stack should only be deployed once per tenancy.

1. Click the Create Policy Stack button on the Datadog OCI integration tile.
2. Accept the Oracle Terms of Use.
3. Leave the option to use custom Terraform providers unchecked.
4. Use the default name and compartment for the stack, or optionally provide your own descriptive name or compartment.
5. Click Next.
6. Leave the tenancy field and current user field as-is.
7. Click Next.
8. Click Create.

Enter DatadogROAuthUser info

1. In the OCI console search bar, search for DatadogROAuthUser and click on the User resource that appears.
2. Copy the user’s OCID value.
3. Paste the value into the User OCID field in the Datadog OCI integration tile.

6. Copy the private key value with these steps: a. Open the downloaded private key .pem file in a text editor, or use a terminal command such as cat to display the file’s contents. b. Copy the entire contents, including -----BEGIN PRIVATE KEY----- and -----END PRIVATE KEY-----.
7. Paste the private key value into the Private Key field on the Datadog OCI integration tile.

Create OCI metric forwarding stack

The metric forwarding stack must be deployed for each combination of tenancy and region to be monitored. For the simplest setup, Datadog recommends creating all the necessary OCI resources with the Oracle Resource Manager (ORM) stack provided below. Alternatively, you can use your existing OCI networking infrastructure.

All resources created by Datadog’s ORM stack are deployed to the compartment specified, and for the region currently selected in the top right of the screen.

1. Click the Create Metric Stack button on the Datadog OCI integration tile.
2. Accept the Oracle Terms of Use.
3. Leave the Custom providers option unchecked.
4. Name the stack and select the compartment to deploy it to.
5. Click Next.
6. In the Datadog API Key field, enter your Datadog API key value.
7. In the Network options section, leave Create VCN checked.

8. In the Metrics settings section, optionally remove any metric namespaces from collection.
9. In the Metrics compartments section, enter a comma-separated list of compartment OCIDs to monitor. Any metric namespace filters selected in the previous step are applied to each compartment.
10. In the Function settings section, select GENERIC_ARM. Select GENERIC_X86 if deploying in a Japan region.
11. Click Next.
12. Click Create.
13. Return to the Datadog OCI integration tile and click Create Configuration.

Notes:

• By default, only the root compartment is selected, and all of the metric namespaces from Step 8 which are present in the compartment are enabled (up to 50 namespaces are supported per connector hub). If you choose to monitor additional compartments, the namespaces added to them are an intersection of namespaces selected and the namespaces present in the compartment.
• You should manage who has access to the Terraform state files of the resource manager stacks. See the Terraform State Files section of the Securing Resource Manager page for more information.

1. Follow the steps in the setup section to create the necessary infrastructure for forwarding both metrics and logs to Datadog.

Metric and log forwarding resources

For each region monitored, this setup option creates the following infrastructure within that region to forward metrics and logs to Datadog:

• Function Application (dd-function-app)
• Two functions:
  • Metrics Forwarder (dd-metrics-forwarder)
  • Logs Forwarder (dd-logs-forwarder)
• VCN (dd-vcn) with secure networking infrastructure:
  • Private subnet (dd-vcn-private-subnet)
  • NAT gateway (dd-vcn-natgateway) for external access to the internet
  • Service gateway (dd-vcn-servicegateway) for internal access to OCI services
• Key Management Service (KMS) vault (datadog-vault) to store the Datadog API key
• Dedicated Datadog compartment (Datadog)

All resources are tagged with ownedby = "datadog".

IAM resources

This setup option creates the following IAM resources to enable data forwarding to Datadog:

• Service user (dd-svc)
• Group (dd-svc-admin) that the service user belongs to
• RSA key pair for API authentication
• OCI API key for the service user
• Dynamic Group (dd-dynamic-group-connectorhubs) that includes all service connectors in the Datadog compartment
• Dynamic Group (dd-dynamic-group-function) that includes all functions in the Datadog compartment
• Policy (dd-svc-policy) to give the service user read access to the tenancy resources, as well as access to manage OCI Service Connector Hubs and OCI Functions in the compartment created and managed by Datadog

- Allow dd-svc-admin to read all-resources in tenancy
- Allow dd-svc-admin to manage serviceconnectors in Datadog compartment
- Allow dd-svc-admin to manage functions-family in Datadog compartment with specific permissions:
     * FN_FUNCTION_UPDATE
     * FN_FUNCTION_LIST
     * FN_APP_LIST
- Endorse dd-svc-admin to read objects in tenancy usage-report

• Policy dd-dynamic-group-policy to enable the service connectors to read data (logs and metrics) and interact with functions. This policy also allows the functions to read secrets in the Datadog compartment (the Datadog API and application keys stored in the KMS vault)

   - Allow dd-dynamic-group-connectorhubs to read log-content in tenancy
   - Allow dd-dynamic-group-connectorhubs to read metrics in tenancy
   - Allow dd-dynamic-group-connectorhubs to use fn-function in Datadog compartment
   - Allow dd-dynamic-group-connectorhubs to use fn-invocation in Datadog compartment
   - Allow dd-dynamic-group-functions to read secret-bundles in Datadog compartment

Metric forwarding resources

This setup option creates an OCI connector hub, function app, and secure networking infrastructure to forward OCI metrics to Datadog. The ORM stack for these resources creates a function container repository for the region in the tenancy, and the Docker image is pushed to it to be used by the function.

IAM resources

This setup option creates:

• Dynamic group with resource.type = 'serviceconnectors', to enable access to the connector hub
• User named DatadogROAuthUser, which Datadog uses to read tenancy resources
• Group to which the created user is added for policy access
• User named DatadogAuthWriteUser, which is used to push Docker images for the function
• Write access group that the DatadogAuthWriteUser is added to, for pushing images through policy access
• Policy in the root compartment to allow connector hubs to read metrics and invoke functions. This policy also gives the created user group read access to both the tenancy resources and write access group, to push images

Allow dynamic-group Default/<GROUP_NAME> to read metrics in tenancy
Allow dynamic-group Default/<GROUP_NAME> to use fn-function in tenancy
Allow dynamic-group Default/<GROUP_NAME> to use fn-invocation in tenancy
Allow group Default/<USER_GROUP_NAME> to read all-resources in tenancy
Allow group Default/<WRITE_USER_GROUP_NAME> to manage repos in tenancy where ANY {request.permission = 'REPOSITORY_READ', request.permission = 'REPOSITORY_UPDATE', request.permission = 'REPOSITORY_CREATE'}
