You guys are monitoring your servers?
"can't access this thing, server must be down"
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.
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).
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
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 there 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.
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.
I notice something stopped working, or someone in the household notices.
Then I go fix it.
And the best time to notice that the backups weren't working is when you need access to the backup. 😅
Backups? In this economy?
But I need to get something working. I am about to move to VaultWarden and that makes me very nervous.
I run a vaultwarden container since forever and it's really smooth. All updates went through just fine, never had an issue with it.
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.
I go the easy route with munin and wazuh. It comes with a ton of stuff preconfigured
Monit, simple to setup, gets the job done, runs on my router too.
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).
Uptime Kuma for monitoring web service status (just like if the jellyfin, etc. website is up), and Zabbix for monitoring system metrics like CPU/Memory/Disk I/O, etc. Zabbix can do a whole lot, but can also get a little complicated. There are plenty of guides out there for configuring it though.
I just look at the console.
Netdata, looking at dashboards when something breaks :)

It's running the private DNS for my phone. If it goes down, I realise quite quickly.
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.
I've been checking several other solutions before and Beszel just hits the spot.
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.
That's the neat part, I don't.
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.
Does this monitoring system also happen to be a dependent on your taxes?
I've got a few of those services running.

Lights are on, server is on.
Kernel panic?
My kernel is chill.
I recently found out that this is not always true.
I never said anything about it responding.
Zabbix
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)
Exactly this scenario at my place as well. 😄
I use nagios
Whining from end users.
I pay a group of schoolchildren to refresh a group of browser tabs and yell if anything isn't responding.
There are plenty of previous threads with recent answers if you search.
