github-actions VS blackbox_exporter

Aha: it's because the project team merged this change that intentionally fails the build when people have pinned their workflows to use the deprecated branch name: https://github.com/google-github-actions/setup-gcloud/pull/5...

(that makes sense; there has been a warning in place for a long time, and pinning to a name can be risky when the content within that reference may change over time)

In the process of finding the answer, I discovered that the small actions are pretty much open-source. I can also go directly to their respective code repositories and learn about them. To run gsutil, I will need a setup-gcloud action.

Like many aspects of the cloud, there are many ways to achieve the same result, but modern software engineering encourages CI/CD processes for several good reasons. As such, we will focus on deploying our service from Github Actions using setup-gcloud

So you need 2 modules, one for each ip version. As for autamating setting these up, we deploy our Prometheus server with salt so we can use Jinja templating in all our Prometheus config files. That really cuts down on repeating boiler plate code.

This is also interesting for other reasons; in host downtime situations you can sometime see they will drop one type of traffic and not the other.

A Pi is more than enough to run a full monitoring stack. Why reinvent the wheel?

You can also use the blackbox_exporter to probe various endpoints. But in reality, you don't need to do this most of the time since the up metric gets you what you want.

Synthetic Monitoring is the Grafana Cloud implementation. It uses the blackbox_exporter

Prometheus blackbox_exporter. Free and open source.

Check something called blackboxexporter https://github.com/prometheus/blackbox_exporter

I have seen some people doing with these traditional relational databases, and I was wondering if it could be a good fit for prometheus+grafana as I have been messing around with prometheus BlackBox exporter (https://github.com/prometheus/blackbox_exporter) for web status monitoring.

You should look into the projects https://github.com/prometheus/node_exporter and https://github.com/prometheus/blackbox_exporter

You could use prometheus as a monitoring tool, blackbox_exporter to "export" the urls to prometheus, alertmanager for notifications, and grafana for nice gui dashboards (and maybe also notifications).
