You guys are monitoring your servers?
“can’t access this thing, server must be down”
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.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.
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.
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.
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?
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.
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.
Lies! It uses electricity!
Indirectly. But as another commenter pointed out, it balances out with the tax rebates.

Uptime Kuma! For HDDs I have them report their “ping” as percentage full
I started with uptime kuma since it was simple and light on resources. I’ve switched to checkmk community (formerly raw) and really enjoying it. It’s telling me so many things that are wrong that I missed. Like that one time I made a snapshot of a VM then forgot about it for 113 days…
@Limeade3425 @user224 how did you discover that with checkmk?
With Uptime Kuma, I just used ping and http sensors so that I knew my stuff was up. When I switched to CheckMK, I installed the agent on all servers and that brought quite a bit more info in, then I added the Proxmox integration and that gave me the snapshot info (as well as more info). I think it automatically pulled in my ZFS info, like zpool status. Then added smart monitoring to my storage so that I can see that my hard drives have been spinning for 13 years and 266 days 😅
13 years?? That machine has never gone fown fo 13 years??
Sorry 😂 I was referring to Power-on hours, so total hours it’s been on (not necessarily consistently)
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. 😅
I have the best detector for issues with my self hosted services: my wife!
Thats cool! My wife thinks i’m crazy just because i homeserve …
Uptime Kuma, only really care if it’s up or not. Got about 30 services monitored, sending notifications to Signal.
Ah cool! How do you get notifications sent to signal. I’ve always avoided because i didnt like emails of my home setup leaving home in clear

Its very finicky to setup, but once you get it working its pretty good. Sometimes needs to be reauthenticated though.
Kuma notification settings:
Looks like i don’t have to expose ports or anything like that, right?
Nope, your uptime kuma speaks to it directly, and it basically acts as a signal client for you.
Edit: ah, i see! It’s kuma that allows you to i guess by adding new device on phone Signal
Lights are on, server is on.
I recently found out that this is not always true.
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.
