This repo demos a synthetic monitor on GCP, i've used as example https://training.zenika.com.

The business use-case i'm monitoring :

1. Navigate on the homepage
2. Type in the search bar for a CKA training
3. Consult a search result page and chose the first result
4. Show be redirected to the training detail page.

• Node.js 18 or higer
• GCP CLI gcloud

make sure dependencies are installed npm install

try executing the monitor locally:

npx functions-framework --target=<YOUR_CLOUD_FUNC_ENTRYPOINT>

next:

• Authenticate to GCP with the gcloud cli: gcloud auth login
• Define the correct project: gcloud set-project <YOUR_PROJECT_ID>
• Deploy your cloud function :

gcloud functions deploy <YOUR_CLOUD_FUNC_NAME> --gen2 --runtime=nodejs18 --region=<REGION> --source=. --entry-point=<YOUR_CLOUD_FUNC_ENTRYPOINT> --memory=2G --timeout=60 --trigger-http

• Create monitor that relies on our cloud function:

gcloud monitoring uptime create <YOUR_MONITOR_NAME> --synthetic-target=projects/<PROJECT_ID>/locations/<REGION>/functions/<YOUR_CLOUD_FUNC_NAME> --period=5

You should be good to go with monitor setup

The cloud function relies on puppeteer to run headless browser, to be as close as possible to the user behavior and to match the web best practices it relied on pptr-testing-library which is an wrapper around puppeteer that provides a set of useful queries. Feel free to chose to use it or not.
