netdata is a fun and simple performance graph for servers. I have this installed on all of my servers.

I centralize the viewing of these metrics by creating several large dashboard pages and hosting them on cerberus and

I create these via scripts located here, the repo has information on the scripts.

To host the graphs I replaced the html directory being hosted by nginx with the /usr/share/netdata/web directory then dropped my html files inside. You can also just make a site for it or use a symlink, it doesnt really matter.
