Running services, network usage, memory usage, bandwidth, disk I/O, successful logins, whether the thing is even alive, etc…
So far my only method has been “hope and pray”.
Use service, wait for 404 or data loss…

I notice something stopped working, or someone in the household notices.
Then I go fix it.
DeathByDenim@lemmy.world 11 hours ago And the best time to notice that the backups weren’t working is when you need access to the backup. 😅

Backups are pretty much the only thing I get notifications for. Otherwise, one app or another on my phone will complain if it loses connection to my server.

Backups? In this economy?
timochka@lemmy.zip 3 hours ago I use Signoz and OTel collectors to bring in everything from Kubernetes (and also SNMP-to-OTel for the network and NAS stats.)
That covers dashboards and basic alerting. Then on top of that I have an n8n workflow that runs every morning - it pulls all the main stats out of Signoz, as well as issues and their status from my infrastructure repo in Gitlab, and feeds it all into a local LLM (Qwen-3.8-Flash-Next at the moment), which emails me a report on overall cluster health. It also automatically opens a ticket in Gitlab for anything that might need fixing.
It works really nicely, gotta say.
owenfromcanada@lemmy.ca 1 day ago I have a robust monitoring system for my Jellyfin server, been running for the last few years. Checks in periodically, at least once per 24 hours and notifies me if it’s down. Doesn’t use any electricity, but does consume a good amount of Cheerios and mac & cheese.
scottmeme@sh.itjust.works 1 day ago
Does this monitoring system also happen to be a dependent on your taxes?

I’ve got a few of those services running.

Indirectly. But as another commenter pointed out, it balances out with the tax rebates.

Well I used to use VGA for my monitors, now its mostly displayport.
Seriously though, prom+Loki+alloy+a few other things to Grafana, with alerting in grafana.

Uptime Kuma! For HDDs I have them report their “ping” as percentage full
WeirdGoesPro@lemmy.dbzer0.com 23 hours ago
Can you teach me this wizardry?
lIlIlIlIlIlIl@lemmy.world 10 hours ago
Sure! In Uptime Kuma, add a monitor with type
Push. It gives you a URL with a unique token, and the monitor goes into “down” state if nothing calls that URL within the heartbeat interval. Then have a cron (or a systemd timer or whatever) run this on the machine with the drive every 5 or 10 minutes:use=$(df --output=pcent /mnt/yourdrive | tail -1 | tr -dc ‘0-9’) curl -fsS -G “http://your-kuma:3001/api/push/TOKEN --data-urlencode “status=up” --data-urlencode “msg=${use}% used” --data-urlencode “ping=${use}”
Pingis of course meant to be response time, but Kuma will graph any number you toss in, so you get a “filled” chart for the drive. I also sendstatus=downonce usage passes a threshold. And if the box itself should fall over for some reason, the missing check-ins trigger the alert too.(I typed this quick on my phone, so please double-check and probably don’t blindly copy-paste)

My primary monitoring system is Beszel, but since I just migrated from VMs to LXCs it can’t properly see the memory/CPU usage, so it just checks for disk usage and liveliness. Home assistant with Proxmox & Dockhand integrations gives me the rest of my monitoring needs.
Alfredolin@lemmy.zip 6 hours ago
I’ve been checking several other solutions before and Beszel just hits the spot.
dimjim@sh.itjust.works 4 hours ago
If you run Proxmox and Proxmox Backup Server, I actually JUST found a better product for my needs, Pulse
My only problem with Beszel is that it doesn’t know about LXCs within Proxmox, so I can’t see if there are CPU/memory issues happening within them. Pulse integrates directly and can see all of it!
If you don’t run LXCs within Proxmox, I’d say stick with Beszel.
sakphul@discuss.tchncs.de 12 hours ago
I am also using Beszel after using checkmk. For me checkmk was way too complicated (but is also way more powerfull) to setup and maintain propperly. So I switcheed to beszel because it is much easier and good enough for my use case which is:
- Is the thing running at all?
- Disk full?
- CPU, network, etc. on full throttle for some strange reason?
- send me a mail if somethings wrong
Besides that I don’t need anything. The only thing missing is SNMP support to check switches, routers and AP’s.

happy_wheels@lemmy.blahaj.zone 1 day ago Cockpit. Total gamechanger for me. I don’t have to ssh to my boxes individually to see what’s going on. Instead it’s a web UI AND you can connect basically every server you want to one instance.
github.com/cockpit-project/cockpit
That said. For individual servers? htop/nmon (nmon is FANTASTIC)
ps -ef | grep <whatever you’re looking for> dmseg tail -f /var/log (or whatever log file you care about) netstatthose are all that come to mind right away.
corsicanguppy@lemmy.ca 18 hours ago
It’s amazing the risk profile of that.
nosuchanon@lemmy.world 17 hours ago
How do you configure adding multiple servers to the same instance?
- happy_wheels@lemmy.blahaj.zone 12 hours ago
So I actually just went to make a guide on this, demonstrating on my ubuntu 26.04 lab vps, and it appears the connect option is not there.
However on my 24.04 lab vps, it’s there. Same with my local 22.04 systems (yes I know I have to upgrade lmao)
I went to cockpit docks and sure enough, the feature is deprecated :( Dang.
docs.cockpit-project.org/…/feature-machines.html
It was really cool though while it worked.
Owljfien@piefed.world 19 hours ago
Lol I go to all of my server’s specific cockpit addresses, sounds like I’m doing it wrong, I’ll need to look at connecting them
- happy_wheels@lemmy.blahaj.zone 12 hours ago
So it turns out… you can’t connect them anymore… The feature is deprecated

popekingjoe@lemmy.world 20 hours ago I usually just walk down the hall and move the mouse. I don’t really need remote monitoring. 😅
esc@piefed.social@piefed.social 18 hours ago
Prometheus + grafana. It’s overkill tbh, most of the services restart automatically and I mostly ignore it. (it’s an artifact from life where I cared about it)
spacelord@sh.itjust.works 14 hours ago
Exactly this scenario at my place as well. 😄
testgoofy@infosec.pub 21 hours ago
I use Alloy to collect Metrics of the host (Disk usage, CPU, Ram, etc.) and different logs. With Grafana the data is then displayed as a daschboard. If everything goes south, Alertmanager sends Mails to me

TrollTrollrolllol@lemmy.world 6 hours ago
I’ll fix it when I get home
I plan to perhaps, just maybe, I am not sure, to try self-hosting an email server. But I’ll need a good uptime.
Although I am really scared about security.
I self-host my own email, have done so for years. I’ve not gotten pwned. Use an SSH key and a firewall, only expose the ports that should be public, have reasonable access controls, etc, just practise general cybersecurity—it applies to servers too.
I know everyone complains about hosting email. But I’ve not run into major problems. My emails get through spam filters and I have good uptime. It’s also a fun learning experience.
bertlewirth@lemmy.world 12 hours ago
Well, it’s a good learning experience. But…… don’t. Good luck getting around the major email providers’ smart screen shit. It’s probably not gonna happen. I tried a few years ago, and even microslop couldn’t figure out why their shit screen crap wouldn’t allow my emails. But it’s worth doing it in the short term to learn how to do it.
InFerNo@lemmy.ml 11 hours ago
Been running one for many years, mostly issue-free. Had to request whitelists way in the beginning, but things turned out ok.
