We recently switched from Grafana to Prometheus. Reason being that a license refresh took longer to process on their end. What happens when a license expires on Grafana? They fucking shut down all your shit cold turkey. Don't care if you're in prod or have a dedicated guy on their end for support or whatever. So you're happily churning along and then suddenly you're blind. Nice FinOps. With Prometheus there's a grace period where they'll happily overcharge you. But we've never had a product absurdly blow up on us like this before. It's truly mind boggling that they're out here talking about 'FinOps' now.
