Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

ZFS for Dummies
I’m on the other end of the spectrum. I like knowing the flags and settings I use to create the pools.
For snapshots and replication take a look at sanoid (https://github.com/jimsalterjrs/sanoid).

Automatic container snapshots? cv4pve or zfs for a small homelab?
I use a combo of PBS and ZFS with Sanoid. The ZFS snapshots are nice because you define it all in a config file with frequent, hourly, daily, weekly, monthly snaps retained however you want. Importantly I use that on the root pool as well as my data pools. With PBS I have a custom retention config and have it backing up VMs and LXCs every couple hours. The PBS dedupe functionality makes it possible to keep full backups going back ages with minimal storage consumption, just the changed blocks. PBS is running inside a VM yes, but it’s storage is on another pool.

New to ZFS, what layout to choose for 4x20TB drives?
No, it's written by the developer of Sanoid and Syncoid. The foremost open source ZFS snapshotting tool. He contributes on this sub all the time.
- Python Port of 600 Line Bash Script: rsync-time-machine.py for Rsync Backups
- Ask HN: Why isn't BTRFS the default FS in home-oriented Linux distributions?
-
Way to extract/see what TrueNAS does behind the GUI?
If you’re looking for snapshot and sync management check out sanoid/ syncoid. Jim’s a mod on r/zfs if you need any help but it’s pretty straight forward. https://github.com/jimsalterjrs/sanoid
- Have you made ZFS volumes yourself and did any of them experience data corruption?
-
Setup a backup system if you haven’t done it yet
There also is sanoid https://github.com/jimsalterjrs/sanoid/ for zfs and btrfs users
-
Do I need zsys or are there alternatives?
You probably do want regular automated snapshots, even if not of specific datasets. I'd recommend my own tool Sanoid for that: https://github.com/jimsalterjrs/sanoid/ ; you can configure it to snapshot the datasets you want snapshotted in the ways you want them snapshotted and nothing else.

Minimum ZFS delegated permissions for Syncoid
The section at the bottom seems to go into your question in pretty good detail, but there’s also an item about this in the Sanoid/Syncoid wiki here: https://github.com/jimsalterjrs/sanoid/wiki/Syncoid.

Webhooks suck, but here are alternatives
In fact, your platform (https://healthchecks.io/) is a prime example of where running customer wasm would be really excellent.
Instead of sending webhooks out to customer configured URLs, you could run a Wasm environment to execute customer code. Off hand, a good use case here is to do further inspection of the event before it gets sent off to some other system - maybe there are cases where you send false-positives and needlessly trigger external system alerts. The customer Wasm could do more introspection on the healthcheck event and make a more informed decision about how to proceed.

What do you use for external monitoring?
i use healthchecks.io and have been very happy
with Uptime Kuma and healthchecks.io, you can do everything. Uptime Kuma to monitor "services" (web server, database), and healthchecks to monitor punctual jobs (backup jobs, etc)
-
Ask HN: How do you monitor your systemd services?
If you are ok with a Saas and if it's just scheduled jobs that you are monitoring, there are a number of monitoring tools where you tell when job completes (with a http request) and a missing ping (after a grace period) means that it failed.
I think https://deadmanssnitch.com/ may have been the original service for this.
https://healthchecks.io/ has a fairly generous free tier that I use now.
There are others that do the same thing Sentry, Uptime Robot, ...

Show HN: Peeng – like Pingdom, but the other way around and simpler
A service in a very similar vein is https://healthchecks.io/ - which also provides a nice perspective on how low-effort the setup for a service with a substantial amount of users can be. https://news.ycombinator.com/item?id=31488910
The blog also contains a bunch of useful information and guides around the topic, including various unusual configurations (arduino/esp8266) as well as information on self-hosting.

Detecting and alerting for power failures
i use https://healthchecks.io/ and highly recommend it.
You can use a service like https://healthchecks.io/ for example. There is an article describing the idea here: https://www.signl4.com/blog/monitoring-still-alive-heartbeat-check/.
