Thruk VS Nagios

There are also a bunch of web interfaces available such as Thruk

I switched from Nagios to Naemon (a fork of Nagios), the migration is super easy, you don't even have to be nonweldable at all in linux to achieve it, and almost all the config files are compatible. It's also compatible with all the Nagios plugins, but the GUI is way better than the one on Nagios (is called Thruk https://www.thruk.org)

Fast forward 12 years and I have Icinga2 collectors in each datacenter using check_by_ssh to run check_systemd, all front-ended by Thruk. The TIG stack is something on my list of things to look into at some point, but with Dynatrace available to do all the fancy application monitoring, there's no rush.

For alerting for Linux systems, I use Icinga with check_ssh and check_systemd (caveat: distributed primarily on PyPI) with Thruk as the single pane of glass front-end to per-datacenter installations of Icinga.

But there are also other solutions out there that can manage the configs for you such as Thruk or Adagios.

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.

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 ?
