make sure it’s configured for clean shut downs before your battery runs out, auto power up on restoration, and hope it doesn’t happen. you will eventually have an outage that outlasts your batteries.

I have a large string of batteries from an old telco office, that runs my rack for 14hrs (calculated, I shut everything down around this time) and that did not last for the 2-3 day outage we had after a storm. Without a generator, you will inevitably have an outage, but if you are prepared, then you can mitigate any damage. use NUT if you need to shutdown or power multiple devices from one monitored UPS

would be a good idea to test the backups on 7, and double check the release notes, they hold just about every caveats. The 7to8 upgrade was not horrible, if you have backups, you could always attempt the upgrade after taking backups, then if successful take new backups, test, then install new drives and restore. depends on how paranoid you feel.

If this was a production system, that is probably the change plan i would follow, but in production I would also be able to migrate VMs. I am not nearly as careful in the home environment.

what about that doesn’t work? just because you don’t know how doesn’t mean not possible.

maybe a vpn provider that uses openvpn? advanced setup but you can have an openvpn client auto connect on boot and bind the mail and ddclient to the tunnel interface.

cloudflare has good support for ddclient, so when your IP changes updates are automatic.

from your router can you ping the AP behind that switch, while the issue is occurring? All L2 unmanaged switches, no tagging? POE from the switch or an injector? If from the switch maybe put an injector in between?

I work for an ISP in the network engineering dept, I personally have never seen an issue exactly like this before, but we generally do power calculations for switching and wifi, this sounds like a power issue to me.

one of the reasons you see these as separate is because of the amount of modularity you get with grafana, you don’t always use it with prometheus, sometimes with ELK sometimes Influx and Telegraf. If you intend to set it up outside of the “typical” you start to really appreciate one piece doing one thing, and doing it well.

i like it, i have been pretty happy with it, but i was also specifically looking for keeping notes in markdown, so ymmv depending on what you want/need. i run it on a docker server i already had, using compose and it has been very stable
