openrc VS Nagios

This isn't added yet but it's being worked on: https://github.com/OpenRC/openrc/pull/573

> It's also not a complete alternative, because it doesn't have anything for user session services like `systemd --user`.

i am working on a implementation of that for openrc for a while now, it's been working nicely so far: https://github.com/OpenRC/openrc/pull/573

With openrc if I don't know what any service does, I can look into the scripts and just read how the config variables get evaluated and how they influence program startup. And no, these scripts are not super complex shell scripts like the sysv-rc legacy stuff on old debian which systemd somehow still gets compared with to propagate FUD. For simple things openrc scripts are barely any more complicated to read/write than systemd service files and for more complex stuff you don't have to trial-and-error your way through systemd's black-box.

It's trivial to write your own openrc service for something.

A lot of those things don't use plain bash either... Of that bigger things in that list:

There is OpenWRT, which uses "procd" (a process management daemon written in C, like systemd but smaller) with its own system bus ubus (like dbus but smaller)

There is Android with its own proprietary init system.

And many others use OpenRC, which is 65% C and 30% shell (according to github). the init files do use shell syntax, but you are supposed to use their interpreter [0] "if you insist on using #!/bin/sh you're on your own" [0]. In fact, the recommended approach is declarative method when you specify name of main binary and their args.. just like systemd.

The world is moving and sysvinit is left behind.

You might also need to check the netmount configuration on your system to make sure it's set to the right interfaces, see https://github.com/OpenRC/openrc/blob/master/conf.d/netmount

that's an old openrc... tagged 2008-05-10 https://github.com/OpenRC/openrc/releases/tag/openrc-0.2.4

Take a look at https://github.com/OpenRC/openrc/blob/master/service-script-guide.md. But there should be plenty other resources on how to create openrc scripts.

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 ?
