Grafana is a terribly ran company that once made a pretty decent OSS dashboard system. Stay away from them for anything but some charts.
What's a good all-in-one cloud monitoring solution that might optionally deal with logs as well?
Log monitoring is not actually a priority at this stage, I just want something to track metrics, chart them and to alert me when the servers are on fire.
Something open-source adjacent and not crazily expensive would be best. As I said I know Prometheus, but for some reason it's so flexible and free form I really do not enjoy using it.
