Grafana is good as a solution because it is easy to offset monitoring and alerting policies in Grafana.

I have seen a return on investment.

All of us in the company have been utilizing Grafana and appreciating its results. Grafana is cost-effective and has provided us with a clear, comprehensive view of our applications, infrastructure, and more.

I have not looked into the ROI.

I can confidently say we have a 100% return on investment. Grafana has greatly enriched our data visualization and analytics. We see the prospect of it appealing even to more senior management. They may not be quite technical, but they appreciate having data nicely visualized so they know what is going on.
