This is the difference in I/O wait times after I replaced the faulty Raspberry Pi memory card to brand new one.

So, from about 8-9 seconds AVERAGES to back almost non-existent! Yay!

Now almost a year ago I blogged about my nine months of experience with running Zabbix on Raspberry Pi 4. I guess it's time to revisit that a bit, as the probably soon-to-fail memory card that came with Raspberry is causing all kinds of issues, even though everything important like Zabbix database is stored on external USB drive.
My Raspberry Pi is still booting from the memory card that came with it. However, I have moved much of the stuff to external USB drive I have connected to Raspberry:
Can you monitor your MacBook behaviour with Zabbix? Of course you can!
My personal Mac is old. It's way too old, actually. It's a MacBook Pro Retina mid-2012 -- yes, I bought it back in August 2012. It has served me well, even so well that with OpenCore Legacy Patcher it has been if not snappy, but fast enough to use for my blogging purposes and so forth. The laptop was running macOS Ventura until few days back, but then I made a mistake -- a big mistake -- as I upgraded it to latest macOS Sonoma.
AIEEEE!!! Potential hiccups ahead for my master server, as today I started to observe these in dmesg output after rebooted my Raspberry Pi.

Just.a quick note: as the Drupal version (9.x) this site was running on is not supported anymore, I migrated the site to Drupal 10.x. As the theme I was using with Drupal 9.x is not compatible with 10.x, the site is for now using the Drupal 10 default theme. That actually looks quite OK, so I'll get back to theming whenever I have time.
Can you monitor NixOS with Zabbix? Of course you can! And that's why I've been silent lately.
Well the bold text is pretty much unnecassary. NixOS is at least semi-supported for Zabbix. I would not set my primary server with NixOS, not with its current state, but for everything else, it's awesome and different.
Thanks everyone for the awesome Zabbix Summit 2023! It was a pleasure, yet again. Here's just a quick update, as unfortunately I was sick for several days last and this week.
Now... the QR code thing I did show to you during my first speech. The next day I told that total I saw about 800 hits to that page. Of course, we had a joker in our audience who wanted to refresh the page more than once, and he admitted that to me after the event on LinkedIn. :)

Can you monitor your ad-blocker with Zabbix? Of course you can!
My home Asus router is running on Asuswrt-Merlin firmware, and with that I have AdGuard Home ad-blocker.
As AdGuard Home has an API, monitoring it with Zabbix is trivial.
Can you monitor tripped fuses with Zabbix? Of course you can!
Some time ago our district heating got some beating. There was a heavy storm which probably did cause the fuse for our district heating device to trip, and I did only notice that after maybe ten hours by accident. I noticed it when I went to check the ventilation control panel, which is in the same closet than our district heating device.
