nebucatnetzer<a href="https://social.linux.pizza/tags/Netdata" class="mention hashtag" rel="nofollow noopener" target="_blank">#Netdata</a> looks nice in general but each client gets a web UI and they seem to push their cloud thing quite hard. I have been burned by too many of these semi open products to get excited about it.

Mika<a href="https://sakurajima.social/tags/Netdata" rel="nofollow noopener" target="_blank">#Netdata</a> has saved my butt - I'd only set it up to get temp monitoring for my <a href="https://sakurajima.social/tags/homelab" rel="nofollow noopener" target="_blank">#homelab</a>, but today I woke up with an alert notifying me that one of my <a href="https://sakurajima.social/tags/Proxmox" rel="nofollow noopener" target="_blank">#Proxmox</a> node's <a href="https://sakurajima.social/tags/ZFS" rel="nofollow noopener" target="_blank">#ZFS</a> pool has degraded. Opening up my Proxmox web interface, checking the main "Summary" and "Disks" tab, nothing would suggest that anything is out of the ordinary - even the failed disk is showing that it had passed its <a href="https://sakurajima.social/tags/SMART" rel="nofollow noopener" target="_blank">#SMART</a> test. It is only when I dug deeper into the "ZFS" section that I could see that one of my <a href="https://sakurajima.social/tags/SiliconPower" rel="nofollow noopener" target="_blank">#SiliconPower</a> NVME disk (avoid at all cost btw) has failed and the ZFS pool has degraded. Fortunately I've an <a href="https://sakurajima.social/tags/ADATA" rel="nofollow noopener" target="_blank">#ADATA</a> SX8200 Pro NVME lying around that I will use as the replacement disk, I've never done this outside of <a href="https://sakurajima.social/tags/TrueNAS" rel="nofollow noopener" target="_blank">#TrueNAS</a>'s web UI, so I'll have to do so while referring to a guide. I'll also link to my guide on setting up Netdata, and will probably write up a guide on how to replace a failed disk in a ZFS pool on my repo after I've done so myself. 🔗 <a href="https://github.com/irfanhakim-as/homelab-wiki/blob/master/topics/proxmox.md#monitoring" rel="nofollow noopener" target="_blank">https://github.com/irfanhakim-as/homelab-wiki/blob/master/topics/proxmox.md#monitoring</a> ▶️ <a href="https://youtu.be/IQA7aTezrVE" rel="nofollow noopener" target="_blank">https://youtu.be/IQA7aTezrVE</a>

For some, it's working now, but I can't seem to get Linkding to work no matter what I do. This is on a <a href="https://caneandable.social/tags/RaspberryPi" class="mention hashtag" rel="nofollow noopener" target="_blank">#RaspberryPi</a> 500 with 8 GB RAM and a 512 GB SD card, running <a href="https://caneandable.social/tags/Stormux" class="mention hashtag" rel="nofollow noopener" target="_blank">#Stormux</a>, which is based on <a href="https://caneandable.social/tags/ArchlinuxARM" class="mention hashtag" rel="nofollow noopener" target="_blank">#ArchlinuxARM</a>. Can anyone help? I'll reply to this post with all my relevant config files in separate posts. What's happening is this: Linkding is supposed to be available at bookmarks.laniesplace.us. When I go there, I see a 401 unauthorized error and a link to sign into Authelia. Once I sign in, though, it redirects back to the page with the 401 error.

MikaI've implemented a Parent-Child <a href="https://sakurajima.social/tags/Netdata" rel="nofollow noopener" target="_blank">#Netdata</a> setup for my <a href="https://sakurajima.social/tags/Proxmox" rel="nofollow noopener" target="_blank">#Proxmox</a> based <a href="https://sakurajima.social/tags/homelab" rel="nofollow noopener" target="_blank">#homelab</a>. I don't get how Netdata get its data for the <a href="https://sakurajima.social/tags/GoSensors" rel="nofollow noopener" target="_blank">#GoSensors</a> section (which I can only assume is what is documented as <a href="https://sakurajima.social/tags/Linux" rel="nofollow noopener" target="_blank">#Linux</a> Sensors on their docs, cos they don't really tell)? I don't have <code>lm-sensors</code> installed on any of my nodes, yet it reports some temps under GoSensors. Problem is, one node has more metrics to report (under GoSensors) than the other, significantly - and none of them have temps of what I want like my <a href="https://sakurajima.social/tags/AMD" rel="nofollow noopener" target="_blank">#AMD</a> CPUs (1700, 5600G). I'm not even sure anymore if Netdata even requires/supports metrics coming from <code>lm-sensors</code> cos it's not mentioned in their docs at all, only seen it being mentioned by their team on their forums. Installing it and after detecting some new sensors, adding them to <code>/etc/modules</code> and restarting the <code>kmod</code> service, also restarting the Netdata service, no new (Sensors) section or (temp) metrics appear on the dashboard. Netdata's documentations are insanely poor. It fools you into thinking it's good with just how many things are documented, but a lot of them are outdated or straight up inaccurate, and there are a lot of missing holes in their docs in general. Also, for wtv reason, you'll find A LOT of dead links thrown out by their team or their users when you scour through their forums, <a href="https://sakurajima.social/tags/Reddit" rel="nofollow noopener" target="_blank">#Reddit</a>, etc. Do they change their URL every month or something? :blobfoxcat: 🔗 <a href="https://learn.netdata.cloud/docs/collecting-metrics/hardware-devices-and-sensors/linux-sensors" rel="nofollow noopener" target="_blank">https://learn.netdata.cloud/docs/collecting-metrics/hardware-devices-and-sensors/linux-sensors</a>
