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).

A data corruption bug in OpenZFS?
https://github.com/openzfs/zfs/issues/15526#issuecomment-181...
> zpool get all tank | grep bclone
> kc3000 bcloneused 442M
> kc3000 bclonesaved 1.42G
> kc3000 bcloneratio 4.30x
> My understanding is this: If the result is 0 for both bcloneused and bclonesaved then it's safe to say that you don't have silent corruption.
It's a very rare race condition, odds are very low that you were impacted. If you were, you would have noticed (heavy builds with files being moved around where suddenly files are zero).

Ask HN: What's your "it's not stupid if it works" story?
A couple years ago, I had an idea for convincing a filesystem to go faster using 2 compression steps instead of one. I couldn't see why it wouldn't work, and I also couldn't convince myself it should.
It seems to have worked out. [1]

ZFS Profiling on Arch Linux
https://github.com/openzfs/zfs/issues/7631
This is a long-standing issue with zvols which affects overall system stability, and has no real solution as of yet.
More details on this discussion: https://github.com/openzfs/zfs/issues/6824#issuecomment-1817... . Basically he is too busy to continue developing the encryption features but is able to review the related works.
There is also discussion about using ZFS on LUKS in the same thread: https://github.com/openzfs/zfs/issues/6824#issuecomment-1819...
ZFS on top of LUKS seems to have it's own issues though. :(

Tell HN: ZFS silent data corruption bugfix – my research results
https://github.com/openzfs/zfs/pull/15529#pullrequestreview-...
Honestly, ZFS is the best thing on the (Free)BSDs only... On Linux it doesn't even use the page cache, and you conflict severely with L2ARC. I know there's a variety of people who don't care, but still for real users it's not an actual option.

In OpenZFS and Btrfs, everyone was just guessing
A more "correct" fix has been posted https://github.com/openzfs/zfs/pull/15615
Current Master: https://github.com/openzfs/zfs/blob/acb33ee1c169bf1c1f687db1...
When I look up the problem, I could only see the issue being discussed, and probably leading to that commit, and then it was not in my current release (2.1) despite several years later. I’m wondering if ZFS still holds that high standard for reliability.
