Here you will find variety of videos and tutorials about different technologies. Mostly covering monitoring and observability with softwares such as Zabbix, Grafana and other. Passionate about Opensource and Homelab initiative. Looking to explore virtualisation opportunities and different gadgets, servers and network equipment that can simplify our day to day operations at home and also in enterprises.
If your goals are to learn about IT Technology and not being only pushed raw knowledge, but also be entertained, then stay tuned.

Great video, thx
This video doesn't talk about Service Now.
that was great i have put an alarm just for the new video am looking to learn more on zabbix from you
Thanks
did not help
Nice video
@DimitryLambert - check with you what should be the basic authentication ?
Great video effectively. One point I missed, maybe because running debian. The need to add the zabbix user to the docker group via sudo usermod -aG docker zabbix. I wonder if you could also make a video related to the install of the zabbix agent within docker to monitor the docker environment (would be handy for my synology environment)
adicionei a linha CacheSize=256M no diretorio sudo vim /etc/zabbix/zabbix_server.conf E funcionou !
Any idea on this after upgrading Failed: cannot extract value from json by path "$.[?(@.id=="clx0t68sw00016ti75jat0ov1")].first()": no data matches the specified path
I am getting error for last function which i have used.(last(anything,#1,30m)) Incorrect value for field "Formula": incorrect expression starting from "last(anything,#1,30m)". Why getting this error and how can i solve this ?
Thanks you help my a settings
Thanks mate, this helped a lot.
Great tutorial! tnx!!!!
Could you please make a video to configure sending telegram alert message with webpage screenshot?
I want to create a trigger for docker restart in Zabbix can anyone help me?
Thanks!
Great video Dmitry! pgadmin is free for pgsql!
I use the express version of dbForge Studio for PostgreSQL, and I like it more than pgAdmin. Its interface is user-friendly, the code completion is excellent, and the overall user experience feels smoother and faster.
Hi, can i install multiple agents via MSI?
its still not work i get error in log file 37041:20240702:022742.305 for a discovery process with 5 workers, the user limit of 1024 file descriptors is insufficient. The maximum number of concurrent checks per worker has been reduced to 122 and when i check with cat /proc/$(cat /var/run/zabbix/zabbix_server.pid)/limits | grep open.files i get Max open files 1024 262144 files when i do sysctl -p fs.file-max = 10000 ps i rebooted server still no changes + instruction works fine
Hi Dmitry, thanks for this tutorial. It helped me a lot to visualize my Zabbix items in Home Assistant. However, there is one crucial hint missing which cost me some time: In the default configuration of the Zabbix server, the StartConnectors are set to 0 and thus no data is sent. In the Zabbix documentation, this is only mentioned in a subordinate clause. After I set the StartConnectors to 1 (1 StartConnector per connector in the Zabbix UI), the items were sent directly to Home Assistant.
THANKS DUDE!
i was wondering why do we migrate to postgresql please dont judge am just in middle of forest
Strange in the cloud it says plugin is installed but it doesn't show up in data sources anywhere. Am I missing something?
One very painful topic is how to monitor process CPU usage under Windows properly?
Hi. My self Venkatesh and from India can u let me know how to monitor manageable switch in zabbix
thànks 4 shàRing
I must disagree with you, the process is different from version to version and it is complicated. I have been using Zabbix since version 4. and everytime i get into upgrade it gets into firefighting mode. this time from 6.0 to 7.0. Repos are not complete for ubuntu 20.04 I had to upgrade to 22.04 to be able to install, then i ran into a database error [Z3005] query failed: [1118] Row size too large. The maximum row size for the used table type, not counting BLOBs, is 8126. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs [alter table `media_type` add `provider` integer default '0' not null]. without a known solution. So sorry to say no it is not the same. for now, I will leave 6.0 as is to avoid the firefighting again.
I spun up a vm with ubuntu 22 on it to test out zabbix 7 with a fresh install. The agent crashed every five minutes, until I downgraded the agent on the server to 6, then it (the agent) became stable. Mostly 7 runs fairly well, however the vm has super high cpu load, and very little cpu usage. Out of the box 4 gigs ram, 4 cores, and 50 gigs of HD space, the exact same environment as my zabbix 6 server, but I already have had to delve into the weeds to fix performance issues. I am now burning the vm running 7 to the ground and sticking with my functional and much less headache free server 6 setup. In a year or so I'll give 7 another chance, but I don't get a big enough budget to waste my time with this level of bug fixing.
If i ever get this issue, i know what video to turn to! Thank You Dmitry!
How can I reconfigure MFA for a user account? The user lost their old code, and now I can't set a new one.
Does 7 allow GitHub authentication?
You can enable 'HTTP authentication' and configure your webserver to manage the authentication in any way you want, but then you loose the 'JIT' part.
Where is the kubernetes documentation?
awesome shirt Dmitry!
How can we upgrade mysql???
So much of the video is about updating postgre What about Mysql? It's default DB on appliances
As we know, the TimescaleDB feature is designed for databases and high-volume, professional environments. In these environments, not using a proxy is impractical and incurs high costs for the main server. However, even in the latest versions, Zabbix proxy does not support this feature, and it is very difficult to choose between TimescaleDB and the proxy!!! I hope a solution for this issue will be found soon.

Hi, I followed your video and I can get the AWS instances in my zabbix, thanks for this helpful video. There is an item instance check failed but it's not generating a problem although I stopped the instance in my AWS console. Can you help me ?
Thank you for this point ! what do you recommend between mysql and postgresql for a zero installation on debian 12 ?
PostgreSQL with TimescaleDB
Hi , can I reboot the host server using the Zabbix script, please I need to add a script that will reboot the host server.
Yes you can via actions. But firstly you need to create script in Alert > Script first.
Thanks for sharing your knowlegment
Hi, I installed version 7 when it was still in Beta. So i'm currently at version 7.0.0beta3. How can i upgrade to the LTS (release) version ?
Exactly like this howto:)
Thank You 🍻
I was waiting for this one ❤
I was attending Zabbix meeting in San Francisco about 2 weeks ago and asked this question. Official answer was it's not recommended for enterprise and big Zabbix deployments, mostly because of the disk size when you use VHD or OVA templates. Also because limited flexibility, it's all in one box... But with ISO we don't have the drive size issue and I got confirmation it's absolutely ok to use in small deployments and there are no security or features disadvantages in an appliance version of Zabbix. So it's not the best practice but at the same time it's ok for small deployments.
And if you want to expand, you can always remove database from appliance server and install a new one on server of your preference.
Thanks
Is it possible with a website does have a login page?
For those who want to automize installation process via GPO, you'll need a tool called Orca (part of Winsdk kit), and then you can create .mst file for .msi, which may have some parameters for silent install of .msi via GPO (for example Server name/address, TLS identity and key, etc). Full list of parameters can be found in zabbix documentation ("Windows agent installation from MSI").
The template requires version 7.2 of Zabbix which does not exist, how can I do it?
Change git branch to 7.0
what about making a dashboard for monitoring alarm system? can Zabbix display it? every time one of the alarm goes off, it shows it on the dashboard.
I love you, my brother. You safe my life!
