Grafana brings data from multiple sources into dashboards, queries and alerts. Grafana OSS is a self-managed visualisation layer; Grafana Cloud adds managed observability services and telemetry backends, while Enterprise provides commercial capabilities. Teams should specify whether they need to visualise existing telemetry or also purchase its collection, storage and operational support.

Sentry helps developers investigate application errors and performance through issue context, traces, replay and related telemetry. It centres the debugging workflow around application behaviour rather than only server health. Teams should match SDK support and the event types they need to a plan, because tracing, errors and other signals have separate usage considerations.
