Just installed netdata.
Wow, LOTS of downloading and compiling. The machine I installed it on is has an Intel I3
processor running at ~2GHz. Installation took about 5 minutes. So probably a bit longer on a RPi.
TONS of info though. Pretty slick!
That’s not so appealing!!! I haven’t tried installing it yet . .
Here’s a screenshot of it in operaton:
A partial screenshot, really, as there is MUCH more data below that shown. i.e. many screens.
I just started a install on a headless RPi and it didn’t start off so well!
pi@raspberrypi:~ $ date
Tue 2 Apr 13:51:32 BST 2019
pi@raspberrypi:~ $ sudo bash <(curl -Ss https://my-netdata.io/kickstart.sh) && date
bash: /dev/fd/63: No such file or directory
pi@raspberrypi:~ $ curl: (23) Failed writing body (314 != 1369)
a (very) quick search on that error turned up this
so the command line given by the netdata readme needs changing for headless over ssh. I’ll come back to it later as I should be doing other stuff.
FWIW, I ran it with:
bash <(curl -Ss https://my-netdata.io/kickstart.sh)
Here’s a file with the screen activity during the install, in case you’re curious…

Depends on your OS I guess. DietPi must download binaries, took less than a minute… 
That must be the case. The machine I installed it on is running Debian Stretch.
Really I think the only issue is the setting up of the database and particularly the username and password. I think if you used the same as the standard Emoncms installation it would be better. That is: Username = emoncms and Password: emonpiemoncmsmysql2016
Your instructions were very useful. Thank you!
Ah, this is because the emonpi introduced a default database password. My guide was based on the LinuxInstall Guide where you created your own password. Thanks for the feedback. I may just make it a bit more generic rather than plump for the default password.
Cheers.
I decided to have another go at this. I installed the latest Buster and then used the EmonScript. This all seemed to go well. I didn’t modify any of the settings within the EmonScript (probably where the problems started). After all the installations finished the RPi needed to reboot. I couldn’t access it via Ethernet > USB using SSH any more. I removed the microSD card and looked at some of the files, eventually I looked at the /boot/config.txt and found the problem. The line “arm_freq = 1200”. I doubt that any RPi Zero are going to operate at this frequency. I commented out this line and all seems good afterwards.

If I want to uinstall it on my PiZero in docker, it always pulls the wrong image and doesnt start. How do you install it then? thanks
I don’t have enough experience with Docker to know how to do this. I think trying to run Docker and EmonCMS on a PiZero might be too much. The resources on the PiZero are very limited.
Thanks
