Healthcheck of your Selfhosting installation - what are you monitoring
and why?

Hey all,


I just found [healthcheck.io](https://healthcheck.io) \- and it's
awesome.
I wrote multiple bash-scripts (via ChatGPT as I'm no programmer), e.g.
\- Check every LXC-Container if the defined docker containers are
still running
\- Update every LXC-Container
\- Refresh the Letsencrypt-Certificat in every LXC-Container

If the tasks is successful, they Ping my
[healthcheck.io](https://healthcheck.io) instance running on a VPS
connected via WireGuard. If the VPS don't get a ping in the defined
timeframe, I get an e-mail notification.

I really love, that I don't have to install anything on the hosts I
want to monitor, so it's always working.


Any ideas of other metrics that are worth to monitor, and that I could
realize with simple bash-scripts?


(I'm using Proxmox with multiple LXC containers running Docker and
apps like Bitwarden, Nextcloud, etc.)

You could do a check for at least 10% disk space available and then do
a ping, so no ping means low disk space?

Check backups have run within the last X hours and ping, no ping means
backups have not ran?

​

There are better ways to track this stuff but if you want to use
health check there are some ideas
