Prerequisites

Before you deploy this sample function, make sure you have run steps A, B and C of the Oracle Functions Quick Start Guide for Cloud Shell

A - Set up your tenancy
B - Create application
C - Set up your Cloud Shell dev environment

List Applications

Assuming you have successfully completed the prerequisites, you should see your application in the list of applications.

fn ls apps

Review and customize the function

Review the following files in the current folder:

the code of the function, func.py
its dependencies, requirements.txt
the function metadata, func.yaml

Create a Datadog API key

In your Datadog account, select Integrations, and under the APIs, click create API key. This will generate your API key.
Replace the value of the DATADOG_TOKEN in the func.yaml

Deploy the function

In Cloud Shell, run the fn deploy command to build this function and its dependencies as a Docker image, push the image to the specified Docker registry, and deploy this function to Oracle Functions in the application created earlier:

fn -v deploy --app <app-name>

e.g.,

fn -v deploy --app myapp

Test

In Cloud Shell, run the following fn invoke command to unit test this function:

fn invoke <app-name> <function-name> < test.json

e.g.,

fn invoke myapp oci-logs-to-datadog-python < test.json

You should see the logs appear in Datadog.

Configure the logs you want to capture

From the OCI Console navigation menu, select Logging, and then select Log Groups.
Click Create Log Group, select your compartment, add a Name and Description
Select Logs in the left menu, click Enable Service Log, select your compartment, select Log Category on Service and fill the rest of the fields appropriately.

Create a Service Connector for reading logs from Logging and send to Functions

From the navigation menu, select Logging, and then select Service Connectors.
Click Create Connector, add a Name, Description, select the compartment, select the Source as Logging and Target as Functions.
On Configure Source connection, select the compartment, select the Log Group created earlier.
