podtato-head VS blackbox_exporter

You should checkout Podtato Head from the CNCF. It has a bunch of different deployment scenarios. https://github.com/podtato-head/podtato-head

https://github.com/podtato-head/podtato-head has great examples of deploying an app using different methods.

Automated deployment of an application via Keptn is typically chained with CI pipelines that generate the images or resource artifacts. In our use-case, the goal is to examine the resilience of one such helloservice application: the CNCF podtato-head. The hypothesis as a developer or user of the helloservice is that (a) the app is nearly always available and (b) accessed within a desired latency. We shall use a pod-kill chaos experiment to disrupt the state and verify if our resilience hypothesis holds true (i.e., whether the service has been built/deployed to meet our expectations). This action is performed when the application is busy serving requests, as this is a real-world case.

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).
