Healthcheck Module for Zabbix 7 – Monitor Zabbix Itself

Keberneth — Sun, 12 Apr 2026 10:14:33 GMT

Hi all,

I’ve published a Healthcheck module for Zabbix 7.

Zabbix monitors your infrastructure, but what monitors Zabbix itself?

This module verifies that the Zabbix API is responding, checks monitored hosts, enabled problem triggers, enabled items, and the freshness of collected item data. If everything passes, it sends a success ping to a configured healthcheck endpoint such as healthchecks.io. If a check fails, the ping is not sent.

That helps detect cases where Zabbix may still be polling hosts, but something on the Zabbix side is failing, or outbound connectivity is broken so alerts and actions never leave the server.

With a service like healthchecks.io, a missed ping can trigger an alert through integrations such as PagerDuty, Teams, Slack, GitHub, and others.

The module also adds frontend pages for heartbeat, history, and settings, and includes a runner you can schedule with systemd or cron.

Zabbix AI module - Game changer, fully integrated AI assistant

Keberneth — Sun, 12 Apr 2026 10:02:48 GMT

Hi all,

I’ve published an AI module for Zabbix 7 that adds AI chat and webhook-based problem analysis.
Fully integrated in Zabbix. No external calls, no external services this module is a part of Zabbix. Copy paste installation.

The webhook can receive triggered problem from trigger action and send details to an AI provider and post the response back as a problem update.

The chat can use session context from a selected host and active trigger to help with troubleshooting and explanation.
AI assistance is also available in multiple Zabbix functions, including items and triggers. When editing an existing trigger or item, you can open the AI panel and ask for help modifying it. The module passes the current configuration and relevant variables to the chat so it can return more accurate suggestions.

From Latest data, it can also include item, trigger, and selected history data for better analysis.

Possible to add integration to Netbox to get even more session context.

The module also includes redaction and logging controls. Sensitive data such as hostnames, IP addresses, FQDNs, URLs, and inventory values can be masked before requests are sent to the AI, and audit logs can be stored locally with redacted payloads.

AI module can also perform actions in Zabbix like: (Can be limited to Super Admins)
Create:
Maintenance windows, Items, triggers, host groups and add hosts to host groups.

Can add different AI's for different tasks. This can improve response and cost by choosing different AI depending on function.
Default chat
Default for webhook
Default for actions

Dedicated Zabbix Sql Server restarts

bep6vaku — Fri, 10 Apr 2026 21:26:11 GMT

I have a dedicated Zabbix SQl running MariaDB ver.15.1 on an Ubuntu 24.04 and when the memory utilization approached 78 or better precent, the SQL service restart. Not sure what is causing this or what settings need to ne adjusted. This is a physical server with 380GB of ram. I looked at the InnoDB settings but not sure if any need to be adjusted: Current version of Zabbix is 7.4.8

innodb_buffer_pool_size = 285G
innodb_log_file_size = 16G
innodb_log_buffer_size = 256M
innodb-file-per-table = 1
innodb_buffer_pool_instances = 16
innodb_old_blocks_time = 1000
innodb_stats_on_metadata = off

Zabbix HA cluster strange behavior

olegus — Fri, 10 Apr 2026 19:32:23 GMT

Hi, we use Zabbix HA cluster functionality (2 servers) and every time we need to do maintenance on active server, we see ~5 min gap in charts. It looks like HA cluster does not work as expected even though a stand-by server correctly switched to Active according to SystemInfo page . We have fallover delay set to 1 min (which is probably too much) - but a gap is longer - up to 7min in some cases.
So when we bring the first server back again, we see all processes running high, struggling to process queues. All our proxies set both server's IPs correctly according to docs.
I wonder if it is expected behavior ? Would it help if we reduce failover delay down to say, 10 sec? What is the best practice here?

How we can discover host but just want discover selected interface only?

kronicklez — Fri, 10 Apr 2026 09:18:39 GMT

HI all,

By default when we discover host using snmp it will discover all the interface in that host. But i want it just discover selected interface only. How to do that?

Appreciate any help.

Zabbix server is not running: the information displayed may not be... (split servers)

Jaceqp — Fri, 10 Apr 2026 08:06:51 GMT

Hi there.
I'm trying to troubleshoot my split zabbix environment. I've had everything up'n'running on all-in-one zabbix srv. Then I created separate servers for frontend and DB, created empty DB and restored backup into it. I guess I tweaked all conf files as expected, reconfigured GUI using IP/zabbix/config.php - went smoothly, no issues connecting to DB...

Anything else to check?

zabbix 7.4.2 + postgresql 17

PS. Here's some issue connecting to DB in logs (kinda weired since gui configurator shows no issues):

Code:

801:20260410:100002.350 database is down: reconnecting in 10 seconds
801:20260410:100012.366 [Z3001] connection to database 'zabbix' failed: [0] FATAL:  password authentication failed for user "zabbix"

Best OS choice for a school district?

John_W — Thu, 09 Apr 2026 17:43:05 GMT

Our school district is considering moving from SolarWinds to Zabbix. I can see Zabbix can be installed on many Linux versions. I have read CentOS is "end of life". Beyond that, is there a "best" Linux variant that is both free and secure to install Zabbix on?

How to preserve SNMP Trap Operational data after new input

jdfranklin2 — Thu, 09 Apr 2026 17:38:10 GMT

Hello,

I have an SNMPv3 Trap set up on my host with triggers for higher severity traps. The problem is, my host is a Broadworks PBX switch with >4000 subscribers and it sends a very large number of SNMP traps, so when my trigger expression is met, the operational data on the problem gets quickly overwritten by new traps that arrive. The problem name doesn't get overwritten, but the operational data does.

The trap text is fairly custom and usually quite verbose (additionally, it does SNMP on port 8001 rather than the standard 161/162), so I have some dependent items to be able to do value mapping for some of the fields and for easier trigger configuration:

We'll focus on the trap.alarmName, snmptrap.fallback, and trap.severity. Here's the fallback setup:

trap.alarmName setup:

and the trap.severity setup

And then here's the trigger expression:

And here's an example. The alarm type bwSipServiceUnavailableReceived came through at 12:42pm local time and has a severity of 3, but it's being overwritten by a trap sent at 1:23pm local time with the alarm name bwSipMaxRetriesExceeded and severity of 1 (which doesn't trigger an alert)

Is it possible to make it so that operational data doesn't get overwritten?

And since I'm on the subject, partially, is there any way to throw away certain trap data based on regex before it gets past the "fallback" step? That might solve my problem, since we get ~2000 traps every hour, most of them low or informational severity. I would still like the operational data to not be overwritten, if possible.

Graph widget data set aggregation uses the last colour in a list instead of the first

Ace — Thu, 09 Apr 2026 10:21:59 GMT

Hello,

As you know, when selecting a data set color in graph widget, further items get assigned a different color by approximation. However the issue is when you aggregate the data set, the resulting color is not the first color which is what you assigned specifically, but the last color of the list of items, which is completely different and often a much darker shade.

I find currently in version 6LTS and plan to upgrade to 7LTS, does anyone know if this issue has been fixed in future versions or if there is a way to change this behavior with a php file edit?

Zabbix version 7.0.25 released?

hrrapozo — Thu, 09 Apr 2026 02:12:23 GMT

So today (4/8/26 - 3:30 pm HST) I was doing the weekly backup of my Zabbix MySQL database. Normally I shutdown the zabbix server, do the backup, perform any Ubuntu OS updates and then reboot the system.

There is also a Alert Trigger Action (email) dealing with Zabbix server. The email informed me that Zabbix server changed to 7.0.25 (it used to be 7.0.24). I do know that 7.0.25rc1 had been released on March 31, 2026 but there was no indication of the stable version of 7.0.25 was ready.

I am not complaining that 7.0.25 came out early but I also noticing that the System Information widget (shown below) says the server version is 7.0.25 but the latest release says 7.0.24.

Is a maintenance period the right way to stop Zabbix triggering alerts?

G0nz0uk — Wed, 08 Apr 2026 14:39:35 GMT

Hello,

We have maintenance on out systems between 2-3am every days and 12-1am for some other devices, what is the easiest way to stop any triggers being fired during this time please?

I've found Data Collection > Maintenance

I'm guessing I can create too here which stay active for some far off date and use tags?

Thanks

Индикатор горизонтальный

djin59 — Wed, 08 Apr 2026 04:16:33 GMT

Есть такое отображение, если посмотреть картинку то Utilization шкала
как такое реализовать столбиком для отображения на 1 узле нескольких данных
к примеру размер бд на сервере субд но чтобы отображались элементы данных в каждый в новой строке

p/s или я не разобрался как это сделать или реально только в строку можно
