I just submitted a PR for a Rockon running netdata:
Although Rockstor’s dashboard provides a quick and instantaneous overview of most of the server’s state, it could be limited for some users who would like to have a more detailed view of the machine’s CPU, RAM, DISK, and NET usage.
Its documentation reads:
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 running top, vmstat, iostat, iotop, sar, systemd-cgtop and a dozen more console tools 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.
You can find more information and links to demo websites on its website:
Any feedback, comments, and improvements are welcome!
