11. When you see a green check mark everything can connect.
12. Click Create.

 

 

[ Create a dashboard and chart ]

You can display the metrics collected by Cloud Monitoring in your own charts and dashboards. In this section you create the charts for the lab metrics and a custom dashboard.

✅ Cloud Functions

A cloud function is a piece of code that runs in response to an event, such as an HTTP request, a message from a messaging service, or a file upload. Cloud events are things that happen in your cloud environment.


Since cloud functions are event-driven, they only run when something happens. This makes them a good choice for tasks that need to be done quickly or that don't need to be running all the time.

 

[ Create a function ]

In this step, you're going to create a cloud function using the console.

1. In the console, on the Navigation menu click VIEW ALL PRODUCTS and click Serverless > Cloud Run functions.
2. Click Create function.
3. In the Create function dialog, enter the following values:

Field	Value
Environment	Cloud Run function
Function name	GCFunction
Region	us-central1
Trigger type	HTTPS
Authentication	Allow unauthenticated invocations
Memory allocated (In Runtime, Build, Connections and Security Settings)	Keep it default
Autoscaling	Set the Maximum number of instance to 5 and then click Next

✅ Monitor and Manage Google Cloud Resources

 

You need to:

• Create a Cloud Storage bucket and share with a second user.
• Create a Pub/Sub topic for the Cloud Run Function to send messages.
• Create a Cloud Run Function that executes every time a new object is created in the Cloud Storage bucket.
• Create an alerting policy to send a notification email about the number of active Cloud Run Function instances.

---

 

Task 1. Create a bucket

 

Task 2. Create a Pub/Sub topic

Task 3. Create the thumbnail Cloud Run Function

1. Create a Cloud Run Function called travel-thumbnail-generator that executes every time an object is created in the bucket travel-bucket-qwiklabs-gcp-04-d0d7a5dbdd66 you created in task 1.
2. Make sure you set the Entry point (Function to execute) to thumbnail and Trigger to Cloud Storage.

Note: You must upload one JPG or PNG image into the bucket to verify the thumbnail was created (after creating the function successfully). 

Task 4. Create an alerting policy

1. Create an alerting policy named Active Cloud Run Function Instances that notifies your personal email account when the number of active Cloud Run Function instances is greater than zero (0).
2. For the metric, be sure to select Cloud Run Function > Function > Active Instances.
