Scaleway plus the other systems you run
On Scaleway
Cockpit gives managed Grafana dashboards for Scaleway products, and it can take metrics you push yourself. Data you push is billed, even when it comes from Scaleway products.
With Opyntel
Opyntel lists every Scaleway Instance next to the services and servers on your other platforms in one table, down and degraded first, so you see it all at a glance. There are no dashboards to build first.
