Dashboards that shows cumulative and averages data for a bundle of servers

Hi! I am a newbie (both in IT and with Grafana).

We started using Grafana at my job, and I was tasked to do a dashboard that show cumulatives and averages data for a bundle of servers.

I am using Grafana 9.0.1 with Prometheus has the data source.

The problem is that most of the pre-made dashboards seems to show only one server at a time on each panel. However, I was asked to do panels with cumulative and averages data for different bundle of servers.

I did found a template that show cumulative CPU, Memory and Disk panels, but I was wondering if there were more pre-made dashboards like that? Or do I have to create/modify queries to fit my need?

For more information, this is the exact panels I need for my Dashboard:
CPU
Allocated
Used
Wait I/O
Memory
Allocated
Used
Disk
IOPs
Latency
R/W counters
Swap
Sized
Used
Network
Throughput
Errors
Processes
Top
Location

If someone have good resources to learn more about Grafana and how to do queries, or a solution for my problem, let me know!

Thank you!
