      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 netdata on both hosts?

            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.sh on 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!

                      For anyone who has this issue in the future.

                      The command stormi provided did fix the problem on a running machine. Unfortunately it did not persist following a reboot.

                      The command: iptables -F

                      Seems to be a better long term solution.

                      Thanks again to @stormi for isolating the issue.

                        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 -F is 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:

                          I would prefer to use the integrated installation, so that I can be assured of compatibility, etc. Thanks in advance. 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.

                                  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?

                                    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.

                                          @stormi Could it be that there is any difference between the "netdata-ui" rpm package you provide and the official netdata rpm packages?

                                          netdata-conf-1.23.2-1.el7.noarch
                                          netdata-data-1.23.2-1.el7.noarch
                                          netdata-1.23.2-1.el7.x86_64
                                          

                                          Or could it be that it's related to XCP-NG 7.x? Because our cluster is still running 7.x ...

                                            There definitly is. Ours is built with xen support. You seem to have enabled CentOS and/or EPEL repositories on your host, which is not recommended.

                                            See https://xcp-ng.org/docs/additionalpackages.html
