We have a license. The pricing varies. It depends on the number of metrics that you want to ingest per day.

Grafana is not entirely open source, as it has three versions: the free, enterprise, and pro versions. Most of the required features are available in the free version of Grafana, which you will use as a visualization tool, while Prometheus will serve as your monitoring tool.

Therefore, you won't use Grafana as a monitoring tool. If you use Grafana's features, they are free of charge. Hence, you can use Prometheus and Grafana to fulfill your needs. However, if you are using MongoDB as your database, its plugin is not available in the free version of Grafana, and you'll need to purchase the enterprise version.

Since Grafana is an open-source solution, it is free of cost.

I give the price an eight out of ten.

Grafana was not an open source, and we had to pay for a license to use it. The same was the case with CashPoint. There was a license, but I'm unaware of how much we were paying.

We use the open-source version of Grafana.

My company uses the open-source version of Grafana, so it's free.

It's free of cost; it operates as an open-source tool.

The pricing is moderate. It is neither too expensive nor overly cheap. 

I am using the open source version. 

You can choose from the fully open-source or enterprise editions. We chose the open-source and did everything in-house. Thorough planning and performance considerations are important, as the tool can be heavy on memory and computing resources.

For me, Grafana is a cheap tool because I don't have to spend much time learning the product since it is a simple solution. I don't know if there are different paid versions of the product.

I use the open source model so it is free. 

The solution is expensive. Although, its price depends on infrastructure.

I'm not involved in licensing but I believe Grafana is a relatively inexpensive solution. 

We are using the open-source license.

We're using the open-source version. 

Unfortunately, I cannot comment on licensing and pricing costs as I am unaware of the pricing details.

You need to purchase the solution's license for its commercial use.

Grafana is free and open source.
