      Thanks for clarification on that issue -- Weird however -- I read through a bunch of those links referenced in your post, and the last post was 2017 which fully described the problem. One of the things in general I hate about github are many tickets are closed without any mention of how the problem was resolved -- or if it wasn't just due to lack of inactivity in the thread. Freenas now dropping package based on this thread information that is almost 3 years old.

        Rebooted my host today and the Netdata graphing is messed up in several sections. The individual VMs are showing broken graphs for every report. The graphs are just dots. No lines.

        Also under the “Disks” section, the graphs are working but the numerical reporting is broken. It’s showing all zeros for Read, Write, and Utilization even though the graphs are showing activity.

        I’m on iPad now looking at it so I can’t post screenshots. Later today I’ll post some captures so you can see what I’m talking about.

        Any other reports of Netdata not working after reboot?

          Small nitpick -- you can tell me to go away. Anyway to install certs so I can view the data using https?

            @Biggen I assume you used the manual install solution?

            @kevdog in XOA, it's automatically done because XO is acting as a reverse proxy. If you are installing it manually, please check the netdata doc: https://docs.netdata.cloud/web/server/#enabling-tls-support

              @olivierlambert That is correct. Latest xcp-ng patches applied. Worked fine until I rebooted host. Now it looks like this:

                Double check the service is enabled 🙂

                  @olivierlambert Yeah it works on other graphs just fine. Just my VM graphs are the messed up ones.

                    Hmm, what am I doing wrong here? I've just upgraded my pool to 8.0, fully patched, and running Premium XOA, but I'm getting the "Netdata plugin is necessary" message. 🤔

                    I even tried changing from the stable channel to latest but it's made no difference. Do I need to re-deploy? (I assume I can just download the config and re-apply it to a fresh instance).

                      @mike Check under Settings > Plugins to be sure the Netdata plugin is active.

                        @mike Is your XOA recent?

                          I was about to 🤦 because no it wasn't, but attempting to enable it generates the error: Netdata is not available on this appliance, please deploy a new one.

                          I guess that answers that! The XOA instance was first installed maybe 18 months ago, so I'm back to my initial question re: backing up the config and importing to a new XOA. Does that keep all of the backup-ng history etc intact?

                          Thanks all, and happy new year etc. 🙂

                              Well, that sort-of worked, but it doesn't copy over any registration info, and my boss with the premium enabled login is off till Monday. Glad I didn't delete the old appliance!

                                You indeed need to re-register the appliance, with the same creds.

                                      I know this topic is quite old but I thought I might add a point here to installing Netdata manually.

                                      Installing Netdata manually
                                      If you want to do it your way, no problem 🙂 Just run yum install netdata-ui on each host you want to monitor and that's it. You can just go on http://host_address:19999 and enjoy all the metrics.

                                      These instructions are correct however at least for me in the xcp-ng 8.0 release there is an active firewall in place. You'll need to open the port 19999 within iptables. The config file for iptables is /etc/sysconfig/iptables. Edit the file to open the port and try to be as restrictive if possible possible filtering by source port. Restart the firewall service:

                                      systemctl restart iptables.service

                                      Access can be further restricted as well within the netdata setup as documented here: https://docs.netdata.cloud/web/server/. You can setup psuedo access-control-lists and even add SSL certs if necessary.

                                        The netdata-ui package automatically opens the 19999 port. It didn't work for you? Any error message during installation?

                                          It does but it's too open, so ones can decide to edit this rule and restrict it further

                                          NETDATA all -- anywhere anywhere

                                            I'll try to install package again manually once I upgrade to 8.1. Unfortunately for me on 8.0 the firewall port wasn't opened. I'll report once I upgrade.
