Running services, network usage, memory usage, bandwidth, disk I/O, successful logins, whether the thing is even alive, etc...

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.

You guys are monitoring your servers?

"can't access this thing, server must be down"

[–] TrollTrollrolllol@lemmy.world 12 points 4 hours ago

I'll fix it when I get home

[–] user224@lemmy.sdf.org 5 points 10 hours ago (3 children)

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.

[–] communism@lemmy.ml 5 points 4 hours ago (1 children)

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.

[–] NotEasyBeingGreen@slrpnk.net 6 points 3 hours ago

I think that you have to do quite a bit more setup on email than most other services. There's SPF and DKIM and DMARC and so on. Plus spam filtering, setting up accounts and authentication, ...

Plus email is arguably more important than anything else, since it's kind of the lowest common denominator of the Internet; your dentist will probably send you an email to remind you of appointments, job offers will arrive via email, password resets arrive via email, and so on.

So it is a bit scary.

Having said that, as long as you're not hosting from a residential IP addresses it is definitely achievable. You can start with one domain and use it for low-value purposes (or for accounts that allow multiple email addresses, like GitHub).

[–] InFerNo@lemmy.ml 4 points 9 hours ago

Been running one for many years, mostly issue-free. Had to request whitelists way in the beginning, but things turned out ok.

Check out this super great guide. https://workaround.org/ispmail-trixie

[–] bertlewirth@lemmy.world 5 points 10 hours ago* (last edited 2 hours ago) (1 children)

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. It’s not in their best interest to fix it. So they don’t. But it’s worth doing it in the short term to learn how to do it. Teaches you about email, spf, dkim etc. which actually does translate to real world skills. I used what I learnt setting it up in my real life job.

[–] Dultas@lemmy.world 3 points 8 hours ago (1 children)

Yeah, email is one of the more annoying things to self host. Google rejects mine because my ISP has all their non static IPs on block lists (even though my IP hasn't changed once since I've been with them it's still not "static", can't change the reverse DNS) and I'm not paying 150% more a month for a business account to get a static IP. I ended up just using a free email relay. Still had to setup SPF, DKIM, DMARC, and all that jazz still.

[–] bertlewirth@lemmy.world 1 points 2 hours ago* (last edited 2 hours ago) (1 children)

Yup. It’s so damn annoying hosting email. Do it once to learn, but don’t do it as a permanent solution. It takes so much maintenance to keep it going, if you even do get it working.

[–] InFerNo@lemmy.ml 1 points 1 hour ago (1 children)

What maintenance do you mean? run OS updates and pay the vps bill. that's true for any self hosted application. which specific maintenance are you referring to?

[–] frongt@lemmy.zip 2 points 1 hour ago

Setting up the newfangled security thing. TLS, DKIM, DMARC, SPF are the big ones over the years. Finding out you've been silently blackisted by a provider and hoping and praying they'll answer your request to unblock. Managing your own spam filter.

[–] CompactFlax@discuss.tchncs.de 17 points 10 hours ago (1 children)

I notice something stopped working, or someone in the household notices.

Then I go fix it.

[–] DeathByDenim@lemmy.world 5 points 9 hours ago (2 children)

And the best time to notice that the backups weren't working is when you need access to the backup. 😅

[–] electric_nan@lemmy.ml 2 points 2 hours ago (1 children)

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.

[–] DeathByDenim@lemmy.world 1 points 1 hour ago

That and degraded RAID!

[–] CompactFlax@discuss.tchncs.de 5 points 8 hours ago* (last edited 8 hours ago) (2 children)

Backups? In this economy?

But I need to get something working. I am about to move to VaultWarden and that makes me very nervous.

[–] Vendetta9076@sh.itjust.works 1 points 1 hour ago

Don't take this as a reason to not do backups, but vaultwarden is essentially its own back up as it replicates the vault everywhere you use the app. I've recovered my vault several times from my phone.

[–] Carol2852@discuss.tchncs.de 2 points 7 hours ago (1 children)

I run a vaultwarden container since forever and it's really smooth. All updates went through just fine, never had an issue with it.

[–] Alfredolin@lemmy.zip 1 points 4 hours ago

Same. And I was also nervous in the beginning, but in the end if you are the only user, you'll have your vault replicated everywhere you have the app.

[–] hsedr@lemmy.zip 1 points 5 hours ago

I am using prometheus-nodeexporter which is scraped by Prometheus and then visualized in Grafana

[–] RIotingPacifist@lemmy.world 3 points 8 hours ago (1 children)

Monit, simple to setup, gets the job done, runs on my router too.

[–] Cyber@feddit.uk 1 points 3 hours ago

I have this on my NAS, works well

[–] moldy_rice@piefed.keyboardvagabond.com 3 points 8 hours ago

I go the easy route with munin and wazuh. It comes with a ton of stuff preconfigured

[–] lka1988@lemmy.dbzer0.com 1 points 8 hours ago

My 3-node Proxmox cluster has a dashboard, my NAS has a dashboard, and Home Assistant has a dashboard. Hell, my gaming PC has a dashboard, too (Webmin and Cockpit).

[–] Kolanaki@pawb.social 1 points 8 hours ago

I just look at the console.

[–] pHr34kY@lemmy.world 7 points 13 hours ago

It's running the private DNS for my phone. If it goes down, I realise quite quickly.

[–] kurcatovium@piefed.social 18 points 16 hours ago

That's the neat part, I don't.

[–] dimjim@sh.itjust.works 5 points 13 hours ago (2 children)

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 1 points 4 hours ago (1 children)

I've been checking several other solutions before and Beszel just hits the spot.

[–] dimjim@sh.itjust.works 1 points 2 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 2 points 10 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.

Uptime Kuma for outages, Prometheus for metrics, rsyslog to Loki backend for logs. Grafana for ingesting Prometheus and Loki data.

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.
