The firewall rule for netdata is clearly missing here on the first host. I don't know why.

What's the output of:
rpm -qa | grep netdataon both hosts? -
[10:28 xcp-ng3 ~]# rpm -qa | grep netdata netdata-1.19.0-3.xcpng8.1.x86_64 netdata-ui-1.19.0-3.xcpng8.1.x86_64[10:29 xcp-ng2 ~]# rpm -qa | grep netdata netdata-1.19.0-3.xcpng8.1.x86_64 netdata-ui-1.19.0-3.xcpng8.1.x86_64 -
I'm glad you were able to spot a difference. My untrained eye still doesn't see the difference.
-
Can you run
/usr/libexec/netdata/xcpng-iptables-restore.shon the host where it's not working and share the output? -
That fixed it, thank you. Any idea why the firewall rule wasn't initially created?
[10:59 xcp-ng3 ~]# /usr/libexec/netdata/xcpng-iptables-restore.sh Applying firewall rules for netdata from /etc/sysconfig/iptables_netdata -
No, I don't know. The iptables rules are rebuilt each time your host starts, and the additional rules for netdata are added when the netdata service starts.

I just realized your icon is from Keen4. I use to play that game when I was much younger.
Thanks again for all your help!

That command I provided is run each time the netdata service starts. So the proper fix is to find out why it doesn't work. Maybe it runs too soon and a dependency needs to be added to another systemd unit.
iptables -Fis NOT a fix nor a "better long term solution". It simply deletes all the iptables rules, so basically you're disabling the firewall. By the way it does not survive a reboot. -
@olivierlambert I'm experiencing something similar. I recently installed XCP-ng, and the trial Premium license. But it also gives me the netdata not available error. I also don't think I have a xapi0:

The product is awesome!

Trying to install it on my xcp-ng host and it having issue with the mirrors.
Do we need to do anything else?
-
You had the same issue with two different mirrors according to the message, so I'd first look at network issues or configuration.
-
Just tired downloading one of the package from my other computer and it worked. issue seem to only be with my xcp-ng host. not sure how to troubleshoot this.
-
I can't help right now myself but I'm sure other users will have ideas. Can you open a separate thread since it's not directly related to netdata?
-
Edit:
Thank you! Got it working and looking good.Troubleshooting non related to Netdata.
I remember I change my upstream DNS to Quad 9 recently (1 week ago) and I just change it to Cloudflair (1.1.1.1) and it was the problem.Look like Quad 9 (9.9.9.9) does not like the Mirrors for some reason.

@olivierlambert Just installed netdata package on our xcp-ng cluster. Its running like expected but i can only get ram / memory metrics from the dom0. Is there any way to get the full ram metrics from all VMs / host?
Thanks
-
As far as I know, they should be available. I/O metrics aren't at the moment, but RAM should be.
