uptime-kuma VS Nagios

Your understanding is correct, unfortunately. Not only that, the developers are also reluctant to make 127.0.0.1:####:#### the default in their READMEs because UsEr cOnVeNiEnCe, e.g. https://github.com/louislam/uptime-kuma/pull/3002 closed WONTFIX

I switched to Kuma recently, but it's not all roses either. Their Docker image is based on Debian 10 with Go 1.19 and they don't feel the need to update because "OS level bugs are seldomely exploitable"

https://github.com/louislam/uptime-kuma/issues/4885

So host it on a separate machine and don't put any secrets in there

If you want more robust monitoring tool that has more ways to monitor your services, websites, beyond dead man’s switch method, check out uptime kuma.

Sigh Nix users.

I need to run uptime kuma, Here is Docker Compose: https://github.com/louislam/uptime-kuma/blob/1.23.X/docker/d...

What is equivalent in Nix?

If you’d like something with a GUI for configuration, I’ve been using [Uptime Kuma](https://github.com/louislam/uptime-kuma) for a couple years now with an “internal” status page for all services in my homelab, and a “public” page for family to see the few services they would care about. I also think [Homepage](https://github.com/gethomepage/homepage) might be a good fit since it links to the services on the page, and has a little indicator dot for if it’s online or not.

Great choice of monitoring and analytics tools (Sentry, Axiom, Posthog and Uptime Kuma) coupled with amazing Slack integrations that allowed us to iron out any issues way before the traffic spike while the troubling features were still fresh from the oven.

You're looking for a dead man's switch. https://deadmanssnitch.com is a good hosted service or Uptime Kuma (https://github.com/louislam/uptime-kuma) can be configured to do the same thing.

GitHub: Nagios GitHub Repository

I've used this opportunity to look at some recent init files.

Here's one of the first I stumbled upon.

https://github.com/NagiosEnterprises/nagioscore/blob/master/...

It's 288 lines long; the LSB dependency nonsense is 8 lines of that.

Then I looked up one for Postgres;

https://wiki.postgresql.org/wiki/Lsb_conforming_init_script

This one is a whooping 356 lines long, LSB is again about 10 lines long, depending whether you count the header or not.

I don't think the "LSB dependency" argument holds water.

wget -O nagioscore.tar.gz https://github.com/NagiosEnterprises/nagioscore/archive/nagios-4.4.12.tar.gz

Might be this bug? https://github.com/NagiosEnterprises/nagioscore/issues/861

As far as i know there is no option to log all executed service checks except the debug log. Probably you are looking for log_service_retries=1 ?
