Netdata does not work

Troubleshooting
1

I have installed netdata today but it doesn’t work.
My Dietpi version is 6.28
The netdata service is inactive and I cannot start it

root@DietPi:~# dietpi-services status netdata
DietPi-Services
─────────────────────────────────────────────────────
Mode: status netdata
[ INFO ] DietPi-Services | netdata inactive (dead)

root@DietPi:~# dietpi-services start netdata
DietPi-Services
─────────────────────────────────────────────────────
Mode: start netdata
[ OK ] DietPi-Services | start : netdata

root@DietPi:~# dietpi-services status netdata
DietPi-Services
─────────────────────────────────────────────────────
Mode: status netdata
[ INFO ] DietPi-Services | netdata inactive (dead


I have checked that the /etc/netdata/netdata.conf directory does not exist

Is there any incompatibility with other software that prevents netdata from working?
I also have “rpimonitor” installed and it works
Thanks in advance.

Hi,

pls can you post following

journalctl -u netdata.service
3

Hi,

root@DietPi:~# journalctl -u netdata.service
– No entries –
root@DietPi:~#


Thanks

hmm ok.

pls can you restart netdata service as follow

systemctl restart netdata.service

and have a look to the netdata logs afterwards. They are located on /var/log/netdata. Maybe the error.log contains some useful information.

Thanks!

root@DietPi:~# systemctl restart netdata.service
root@DietPi:~# dietpi-services status netdata

cat: netdata: No such file or directory

strange, something seams to be wrong with your installation. At least the netdata log folder should exist because without, netdata is not able to start. pla can you try to start netdata manually

/usr/sbin/netdata -D

Thanks

root@DietPi:/usr/sbin# netdata -D
-bash: netdata: command not found
root@DietPi:/usr/sbin# ls n*
netfilter-persistent newusers nfnl_osf nologin
root@DietPi:/usr/sbin#


I tried yesterday to install, uninstall, install

you are missing the netdata executable. Pls can you try to reinstall

dietpi-software reinstall 65

Thanks!

ah ok you are still on debian stretch. Looks like uninstall - reinstall caused some inconsistency on your system. pls can you do the following

sed -i '/netdata/d' /var/lib/dpkg/statoverride
dietpi-software reinstall 65

once done pls create the following 2 files and copy the content from attached zip file

nano /etc/netdata/netdata.conf
nano /etc/netdata/edit-config

netdata.zip (1.45 KB)
once done restart netdata and check status

systemctl restart netdata.service
systemctl status netdata.service

yes I have seen it as well on my test system but did not find a way around yet. Did it impact your system? are you able to access Netdata?

13

Great, it works !!! :smiley:
Thanks!

I had to edit the file /etc/netdata/netdata.conf and change the line bind socket to IP = 127.0.0.1 to match the local network IP

hm strange, because the netdata.conf file was the original one that was created right after first installation. But anyway it’s working now.

15

I also had some issues this evening.
Seems the executable wasn’t installed until i re-installed as per posts on page 1 and then I did not get working net data until I followed tec13 and changed the bind address to local server ip.

16

I guess you are on Debian Stretch as well. On Buster this should not happen. At least that how it was on my tests

17

I’m on DietPi

18

:sunglasses: weil DietPi is not an own OS. It is a set of script on top of a Debian base image. For example on Raspberry Pi the base image is Raspbian Lite. For other boards it’s Armbian. Stretch and Baster are the Debian versions. Where Buster is the current version and Stretch the one before.

19

ok, I kinda knew that DietPi was a version of Debian. Anyway, mine was downloaded a week ago - the version for Odroid HC1

Can you let me know the image you downloaded exactly? The current official one is based on Debian Stretch but there was already a new Debian Buster image created. It still has the testing flag but should work already. On Buster the issue should be gone.
