Welcome from Latvia! From Zabbix homeland.

Thank you so much!

[@AaronMolligan]

I tried setting up a docker solution for zabbix many many months ago and it was a headache. The easiest solution was to run the dam thing as a virtual machine. Where it took me days tinkering and stressing out myself without any luck it took me literally 10 minutes to have it up and running as a vm. It's still up and working perfectly for the company I work for and the backing up..OMG so easy.

[@talbech]

Very nice video. Been using Zabbix for several years for monitoring a small data center setup across 3 locations. The proxy function works well for situations like that. I don't particular like the interface, but using Zabbix more as a back-end with a Grafana front-end works well for us. Had to switch to a SQL cluster to make the Zabbix scale a little better. Zabbix/Graylog/Grafana makes a great monitoring solution for smaller installations. Less than 300 devices. May I suggest Graylog for a future video.

[@AwesomeOpenSource]

I will absolutely take a look at Graylog. Thanks for the suggestion!

[@Michael201078]

I use Zabbix for ages. Good reliable and free system. Very convinient for OS monitoring. But need some knowledge to install.

[@AwesomeOpenSource]

Indeed, it is a big one, and getting the settings isn't easy, but their docker stuff is really ready to go other than the few changes I made. It leaves a lot of room for tweaking as you get more into it, so for me that's a huge bonus!

[@mrjazze1520]

@brian, Great job on sharing all the awesome opensource project. FYI: I have noticed in several of your recent videos that you have been cutting out key points in the videos during editing. Case and point at 12:35 while editing the .env_db_mysql_proxy file there is a jump/skip of key information. The audio gives the impression you didn't change anything in the file, but is not the case. Go back and view like the previous 3 vids and you see simular issues.

[@AwesomeOpenSource]

I do occasionally cut certain parts. I'll make edits in some cases, but if the edits are not necessary, just something I did, then I'll cut that part for time sometimes. I ran the Zabbix setup and install 6 or 7 times before recording, then did it a few times while recording, and I take bits from each piece. Most likely why you are noticing these little jump cuts here an there...but almost talways I cut parts that aren't necessary bits to trim down my already very long form content.

I've used Zabbix for years now and it just keeps getting better and better. Flexible as well! I use Node-Red to grab and process data from a flaky energy meter and send the data to Zabbix. I also have a trigger when I don't get data for 5 mins to run an expect script that logs into a PDU the energy meter is connected to and toggles the power to reset it.

I love how you all have such great ways of getting things done. I would love to start collecting up "how to" from everyone on these videos. Maybe I can setup a wiki for sharing more ways of doing these things.

[@itsmith32]

Dear Author, thank you so much for your great video on Zabbix install! Even though there are lot of changes now in Zabbix repo, it is still worth to follow your guide. It would be very useful to find out how to set up zabbix-agent on the host machine. I've been trying to find some guides about that, but unfortunately I can't. Looks like I'm setting config in the wrong way and cant even start service, even though it is running like a charm on a similar install on another host. I would appreciate if you will share your ideas about that. Keep up your brilliant work!

Let me see what I can do. Glad it was helpful.

@@AwesomeOpenSource I have eth0 and tailscale0 interfaces, alongside with all of those bridges created by docker. Playing with addresses I have found a way to run zabbix-agent successfully at host OS, but Zabbix server still cannot get anything from agent.

So, you may need to make sure the host os can talk through the docker gateway address to the port that Zabbix server listens on. Not sure it will work, but should in theory.

A huge problem with zabbix is its lack of DNS caching. if you use DNS names instead of IPs then your DNS servers, with 50 hosts loaded into zabbix, will be hit approximately 46000 times a minute. a local DNS caching server is required for this. otherwise only use IPs and set everything being monitored with zabbix as static addresses. Zabbix otherwise is a great software and monitoring system. with our system, we have specifically denied all DNS requests from the zabbix server and all clients have the agent config set with just IPs.

Great Video, but how do you solve the problem with the Zabbix Server in red?

[@AwesomeOpenSource]

I apologize, it's been so long since I did this video that I don't recall what I had to do...I think, however I just had to allow it access to itself. I think it was just a port issue, but not 100^ certain anymore.

[@dimitristsoutsouras2712]

While you were deploying this with docker-compose up && ,...... was there an option to specify if the container would be privileged or not? That may solve the problems you had afterwards? Or is this something completely irrelevant? Thank you

[@AwesomeOpenSource]

I didn't see an option for that specifically in their documentation. I found an article from someone else who was seeing the same issue, and since Docker creates its own firewall rules, it appeared to be an issue with the docker firewall... you can adjust those rules in the container with iptables commands, but if you do docker-compose down, then docker-compose up again, it will reinstate the original blocking rules. There could, however, be a more elegant solution that I'm just not aware of.

Great video (as always 😉). Quick one: I'm using Portainer to manage stacks and containers, and would like to create a stack from the docker-compose.yml file. I understand I'll have to use absolute path to the .env_* files (in env_vars folder) but the yml file references a ./zbx_env/var/lib/... folder which I cannot find in the folder tree created from git: is it created at runtime or should I create it before creating the stack? Thanks in advance for any help!

[@AwesomeOpenSource]

I said it in the video, but admittedly very quickly..the ./zbx_env folder is created when the docker-compose is run...so it's not there at the time you are editing the vars. Hope that helps.

This will absolutely work on windows machines. They have agents for all of the major OSes, and you can also use SNMP for various systems.

Uw this looks super fun to spin up a ubuntu server and test on... Question though, i'm following along with the video. If my host OS is ubuntu server any reason I wouldn't want to use the compose file with ubuntu in it? 🤔

I don't think it maters which one you use. Alpine will be a smaller footprint generally, but if you have the space, and you're more comfortable with ubuntu, it should be fine.

Zabbix really struggles with any sort of scaling. Beyond a handful of servers (20 or so) it really starts to crap out. Especially if you use any templates that collect a lot of data. It will also just completely die if you do a lot of backups and such over night. We need to restart our Zabbix server every hour. The default parameters for config cache fills up after bout 45 servers. You need to set at least 256MB for the config cache. Many people configure 1GB. The other cache values also need tweaked for each environment. You'll also need at minimum 50 pollers and tons of proxies. Probably 1 proxy for every 20 servers is a good place to start. If you spend any time on the Zabbix forum you'll find overall system performance and long term stability is a big issue. Not to mention you won't get any real support on the forums.

[@AwesomeOpenSource]

This sounds like a job for Kubernetes clustering. You could setup your zabbix in a small cluster of kubernetes systems to help load balance and scale in and out as needed.

[@techmattr8483]

@@AwesomeOpenSource Maybe in a homelab or shop that already utilizes kubernetes that would be a great solution but trying to deploy kubernetes clusters in a shop for a single use case just isn't a reality. It's hard enough getting buy in for a standalone docker container.

[@veepee78]

I dont recognise that kind of problems with zabbix. There are demos of thousands of monitored devices and I have experience for few hundred devices, with no performance issues. And what comes to scaling it scales nicely with proxies.

[@SB-qm5wg]

I know nothing of Zabbix. 1st I've heard of this. But what I would do is check the backend DB for performance issue. Modify OS configs if needed like dynamic hugepage and the like. I'm sure Zab already has correct table indexing. I've worked with software like this for over a decade. If the SNMP pollers aren't holding things up and it's not obvious hardware bottlenecks, I'd go to the DB.

I think 2 things could be going on. The first part about the resources ignored, is that part I talk about in the video where docker-compose ignores the resource limit parts... that's really for docker-swarm. No issue for that, just ignore it as well. The errors, may be due to either an older version of docker (are you using docker.io vs docker-ce?) I would suggest installing docker-ce, and you may need to install a newer version of docker-compose. I had to update my docker-compose from 1.25.x to 1.29.x in order for it to work properly. Maybe that will help. Let me know.
