Show HN: The simplest centralized logs management ever, with SystemD and Netdata
I started the discussion, and offered a solution too:
ok, can we discuss how you see this working for you? How do you believe you can provide SSO to all your Netdata agents?
Please open a discussion here: https://github.com/netdata/netdata/discussions
Even if this may be a niche need, I am open to create such a feature for those that need it, at a small price. But we need some specs.

μMon: Stupid simple monitoring
hey - I work on ML at Netdata (disclaimer).
We have a big PR open and under review at moment that brings in a lot more logs capabilities: https://github.com/netdata/netdata/pull/13291
We also have some specific logs collectors too - i think in here might be best place to look around at the moment, should take you to the logs part of the integrations section in our demo space (no login needed, sorry for the long horrible url, we adding this section to our docs soon but at moment only lives in the app)

Ask HN: How do you monitor your systemd services?
> So I turned to Netdata. A one liner on each server and we had super sexy and fast dashboard for each server. No birds eye view, but fine. I then spent maybe 3-4 days trying to figure out how to get alerting to work (just email, but fine) and get temperature readings (or something like that).
I work in Netdata. Just wanted to mention that as of last release a parent node will show all children in the agent dashboard so if doing again as of today a parent netdata might have got you the birds eye view as a starting point https://github.com/netdata/netdata/releases/tag/v1.41.0

Questions about Netdata update size/how to disable or move from nightly to stable?
Stable releases are a bit more complicated. Major and minor releases are typically once every few months at the moment, but do not have a consistent release schedule (we’re trying to shift internally to having a consistent release schedule though for these, likely every six to eight weeks). Patch releases are published as needed (either when some serious issue is discovered with the associated release, or when we have enough easily backported fixes in the nightlies to warrant a patch release). You can watch releases at https://github.com/netdata/netdata to see when stable releases are published (though again do note that native packages get published asynchronously relative to these releases being published).

OpenRC is a dependency-based init system for Unix-like systems
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.

Can't get Nagios to work on Ubuntu 22.04
Also, dang it. I told them they needed to update that Core installation doc. You're installing the latest version of Core, right? The one they mention in the doc is like 4.4.6, and 4.4.12 was released today. https://github.com/NagiosEnterprises/nagioscore/releases/tag/nagios-4.4.12
wget -O nagioscore.tar.gz https://github.com/NagiosEnterprises/nagioscore/archive/nagios-4.4.12.tar.gz
- Is Nagios Core still alive? Last commit on 18 Jul 2020 😳
