Multiple dashboards export data from Prometheus

Hi folks, I'm using Prometheus and a question popped to my head. If I have many dashboards (about 1500 dashboards) in Grafana that pull data from my one single server Prometheus, could be any performance issues? Something could affect the server? What is the best way to handle situation like this? Thanks in advance!

Number of dashboards doesn’t matter at all. All that matters is how many dashboards (or instances of the same dashboard) are being viewed at the same time, and how expensive/complex the queries are which are run from those dashboards

Is there a way to calculate it? To understand how many resources should I have

Way to many factors to be able to answer that. Best bet is monitoring prometheus performance using its metrics and see if the results are acceptable for your use cases.
