Overview	Grafana is an open source visualization and dashboarding platform that queries metrics, logs, and traces from Prometheus, Loki, Tempo, and dozens of other backends, with Grafana Cloud offering a hosted option.	Datadog collects infrastructure metrics, logs, traces, and other signals so teams can investigate services and configure alerts.	Prometheus scrapes time-series metrics from instrumented targets, stores them locally, and evaluates alerting rules with PromQL, forwarding alerts to Alertmanager. It has no built-in dashboarding or long-term storage layer of its own.
