How to monitor server resources?

Question

linux

I have never encountered server administration, I only used linux on the client. Please throw me links to the least confused and most visual means of monitoring server resources on ubuntu/nginx/php. I would like to - view the load on the server with graphs, view available resources, processes, network monitoring.
