Hello Experts,

How are you all. My name is Pavan, working on Prometheus dash board. I am very very new to this tool. I have read document to import dash board to generate Host level metrics. I have imported Node Exporter Full dash board and i do see very nice graph. Many Many Thanks to the developer " idealista" for saving lot of time.

I do see it has several panels in the dash board. is there any document that covers detailed information /interpret data on each panel in the dash board for better understanding. if yes, kindly let me know.
also is there any way to find any other plugins Top 10 CPU/ memory/ IO process that is running on server.

Thank you so much.
