netdata is a system for distributed real-time performance and health monitoring. It provides unparalleled insights, in real-time, of everything happening on the system it runs (including applications such as web and database servers), using modern interactive web dashboards.
netdata is fast and efficient, designed to permanently run on all systems (physical & virtual servers, containers, IoT devices), without disrupting their core function.
I already deployed it on RPi 1 (!) and the performance is awesome even with default settings, but there are also some IoT perf. tweaks I will be adding with ansible:
There’s also a sensors library, so it’s a great way to keep track of data of them in real time.
It’s also a good way to check performance and resource usage of existing projects with minimal footprint on them.
