+==== Netdata ====
+https://github.com/firehol/netdata/wiki
+netdata is a scalable, distributed, real-time, performance and health monitoring solution for Linux, FreeBSD and MacOS. It is open-source too.
+Out of the box, it collects 1k to 5k metrics per server per second. It is the corresponding of: top, vmstat, iostat, iotop, sar, systemd-cgtop and a dozen more console tools running in parallel. netdata is very efficient in this: the daemon needs just 1% to 3% cpu of a single core, even when it runs on IoT.
+Many people view netdata as a collectd + graphite + grafana alternative, or compare it with cacti or munin. All these are really great tools, but they are not netdata. Let's see why.
+My primary goal when I was designing netdata was to help us find why our systems and applications are slow or misbehaving. To provide a system that could kill the console for performance monitoring.
+To do this, I decided that:
+  * high resolution metrics is more important than long history
+  * the more metrics collected, the better - we should not fear to add 1k metrics more
+  * effective monitoring starts with monitoring everything about each node

+Prometheus differs from Loki by focusing on **metrics instead of logs**, and delivering logs via **pull**, instead of **push**.
