Grafana Labs has raised a Series A and wrote up on their blog what it all means for the open source world.

With this fund raise, we are committed to investing even more in the open source community. That goes hand-in-hand with pushing forward with our vision of building an open, composable observability platform that brings together the three pillars of observability – logs, metrics, and traces – in a single experience, with Grafana at the center. This will allow users to choose their favorite combinations of observability tooling and bring them all together in one UX – an industry first.
