@evamik @prettygood @hj If you want something that requires barely any work to set up, you might like Netdata. But it's very hard to recommend for me, because they push their cloud service very aggressively (1) and the feature that previously removed that functionality was removed. They also collect metrics by default (can be disabled at install time with a flag to their install script, or by creating a hidden file in the Netdata config folder). It can also be somewhat intimidating at first, because it collects everything it can.

(1) The only way to go to the dashboard without going through another "dashboard" that is essentially an ad for their service is to append /v3 to the URL.
