I use netdata (the FOSS agent only, not the cloud offering) on all my servers (physical, VMs…) and stream all metrics to a parent netdata instance. It works extremely well for me.
Other solutions are too cumbersome and heavy on maintenance for me. You can query netdata from prometheus/grafana [1] if you really need custom dashboards.
I guess you wouldn’t be able to install it on the router/switch but there is a SNMP collector which should be able to query bandwidth info from the network appliances.
It should be possible using script to execute on alarm = /your/custom/remediation-script…netdata.cloud/…/agent-notifications-reference. I have not experimented with this yet, but soon will (implementing a custom notification channel for specific alarms)
restarting a service if it isn’t answering requests
I’d rather find the root cause of the downtime/malfunction instead of blindly restarting the service, just my 2 cents.
I agree that desktop/ATX tower PCs are the most useful form factor, you can stuff all your old junk hardware in there and offer it a second life without much investment.
However with current electricity prices buying more power efficient hardware can be a better medium-term investment. 1kWh bills at 0.2516€ currently where I’m at (~EU average price), assuming an average power consumption of 50W this gives you (50×24×365)/1000×0.2516=110€/year. At this rate a 200€ investment in hardware would pay for itself in 2-3 years.
Buying a <100€ setup is not worth it for general purpose servers in my opinion, it will either be underpowered or power hungry.
My current solution is to to run all my services in KVM (libvirt) VMs on my beefy desktop computer which is already on most of the time anyway. Best of both worlds.
If I had to redo everything I would probably buy a NUC/mini-PC with a good CPU, 64GB RAM and low power consumption, stash a single huge SSD in there, migrate my VMs there and call it a day. But this is not a cheap setup.
Hello, I’m relatively new to self-hosting and recently started using Unraid, which I find fantastic! I’m now considering upgrading my storage capacity by purchasing either an 8TB or 10TB hard drive. I’m exploring both new and used options to find the best deal. However, I’ve noticed that prices vary based on the specific...
I’m duplicating my server hardware and moving the second set off site. I want to keep the data live since the whole system will be load balanced with my on site system. I’ve contemplated tools like syncthing to make a 1 to 1 copy of the data to NAS B but i know there has to be a better way. What have you used successfully?
Netdata can also expose metrics to prometheus which you can then use in Grafana for more advanced/customizable dashboards learn.netdata.cloud/docs/…/prometheus
The primary OS for this disk was Unraid. Its formated in BTRFS. I don’t think either of those matter. The disk spins and worked before the reboot. But now. No matter what machine, port or cable I use its not mountable. Is there anything I can try? I was going to attempt Spinrite on it however it doesn’t see anything either....
