Observability is becoming mission critical, but who watches the watchmen?

The last couple of years, there has been quite a lot of development in the area of lowering the barrier of entry for observability. There are now quite a few, reasonably mature options out there that lets you set up a good monitoring stack either through a few clicks or by a few one-liners in the terminal.

In the managed open-source space, the most successful one so far probably is Grafana Cloud, but there definitely is no shortage of closed-source vendors providing APM solutions where everything you need to get started is to drop either a single or multiple agents into your cluster or your machine.
