ZBXNEXT-1070 workaround by read-only items/triggers/... database tables replica?

user185953 — Mon, 12 Oct 2026 07:45:02 GMT

Kevin Rodrigues Sometimes you just have to get a bit creative. You could pull the information through the API, including the host relations, or build a Grafana dashboard that queries the database directly. That way you can search by host or filter by template. There's usually a way to solve it if you're willing to look for one.

Idea is a separate zabbix where users have "read/write" access but database tables hosts/templates/items/triggers/proxies/... are read-only replicated from production. Most zabbix server processes disabled to block data collection.

Can this work?

Monitoring Multiple SQL Server Instances

bertman — Thu, 08 Oct 2026 09:28:32 GMT

Hello,

We have a server with two Microsoft SQL Server instances. How can we monitor both instances?
In the host macros for tsrv045, I can configure only one instance using {$MSSQL.URI}.
I could create a separate host for the second instance, but the client is configured to send its data to tsrv045. Therefore, creating a second host would not be useful, as that host would not receive any data from the agent.
What would be the recommended way to monitor both SQL Server instances on the same server?

Regards,
Bert

Corrupt Database Table: history_uint

NismoC32 — Fri, 02 Oct 2026 09:46:06 GMT

After creating a Memory usage table on the Dashboard I get an error message regarding
the table history_uint.

I loggen in to the DB and did a CHECK TABLE and got this:

MariaDB [(none)]> use zabbix
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
MariaDB [zabbix]> CHECK TABLE history_uint;
+---------------------+-------+----------+------------------------------------------------------------------------------+
| Table | Op | Msg_type| Msg_text |
+---------------------+-------+----------+------------------------------------------------------------------------------+
| zabbix.history_uint | check | Error | Got error 194 "Tablespace is missing for a table" from storage engine InnoDB |
| zabbix.history_uint | check | error | Corrupt |
+---------------------+-------+----------+------------------------------------------------------------------------------+
2 rows in set (0.000 sec)

I have very little knowlage of MariaDB.
So it would be really nice if someone could help me how I could go about fix this.

I'm using zabbix 7.0.31 and MariaDB v 11.8.6-MariaDB-0+deb13u1

need to exclude /sys/firmware/efi/efivars from vfs.fs.get

AlexeySaff — Wed, 30 Sep 2026 05:11:38 GMT

Hi, on DELL/HP systems, calling vfs.fs.get provides 2 SMI interrupts at the idrac/ilo level, which dramatically increase osjitter. Is it possible somehow to completely exclude reading this partition? Applying it at the host level doesn't work, as it only filters it.

Docker images for Zabbix 7.4.15 still unavailable after release

Tobias Petri — Fri, 25 Sep 2026 10:40:36 GMT

Hello Zabbix Team,

I am currently waiting to update our Docker-based Zabbix installation from 7.4.14 to 7.4.15.

Zabbix 7.4.15 was released on September 23, but the corresponding production Docker images still do not appear to be fully available on Docker Hub.

In particular, I am waiting for the 7.4.15 images for components such as:

zabbix-server-pgsql
zabbix-web-nginx-pgsql

I can already see some 7.4.15-related build images being published, but the normal server and frontend images still seem to be missing or still point to 7.4.14.

I also noticed that several recent Docker image build workflows in the zabbix-docker GitHub repository were cancelled or failed, so I am wondering whether there is currently an issue with the Docker image publishing pipeline.

Is this a known issue?

Do you have an estimated time for when the complete Zabbix 7.4.15 Docker images will be available on Docker Hub?

Thank you!

Normalizing printer supply names -

furicle — Thu, 24 Sep 2026 20:47:26 GMT

Zabbix 7.4 on Alma 9

I'm monitoring a number of network printers using the Universal Printer template and snmp

It works well, but different manufacturers have different names for their supplies. So when I try to build a dashboard for just the supplies, I end up with multiple entries like

"Remaining Black Toner Cartridge S/N:CRUM-123456789"
"Remaining Black Toner" and
"Remaining Black Cartridge"

depending on manufacturer.

I mucked around a bit and tried to put regex in preprocessing on the five item prototypes in the template of universal printer

Code:

(?i)^(.*?)\s*(?:toner\s*)?(?:cartridge|module|s/n).*

replace with

Code:

 \1 Toner

but that doesn't seem to be working. Feels like I'm in the wrong spot?

Where do I insert the regex to standardize things?

Zabbix logs fill up the /var directory in a week

John_W — Thu, 24 Sep 2026 14:34:12 GMT

We have a 30gig for the /dev/mapper/ubuntu--vg-ubuntu--lv folder and it gets filled up. I checked the /var/log/zabbix folder and found the zabbix_server.log and zabbix_server.log.1 files were very big. We have the server VM setup with 8gig of memory and 32Gig of storage. This is a new install, so we only have a couple hosts setup and not much monitoring.

What do I need to do to fix this issue?

Discovery action continues to process old IP ranges after rule modification

EddieDMorel — Mon, 21 Sep 2026 16:09:41 GMT

Hello there,

We are experiencing an issue with Zabbix network discovery rules (Zabbix version: 7.0.29).
We use discovery rules to automatically create hosts within specific IP ranges. When we modify a discovery rule and replace its IP range with a new one, Zabbix continues to discover and create hosts from the old IP range, even though that range is no longer configured in the rule.
To work around the issue, we created a cleanup action that removes hosts that do not belong to the new IP range. However, this results in a loop: the hosts are deleted by the cleanup process and then recreated again by discovery shortly afterward.
From our observations, it appears that the discovery process continues to scan both the old and the new IP ranges after the rule has been modified. The only successful workaround we have found so far is to completely delete the discovery rule and its associated actions, then recreate them from scratch using the new IP range.

We would like to understand what could cause Zabbix to continue discovering hosts from IP ranges that are no longer configured and whether there is any cache, proxy data, or discovery-related information that needs to be cleared after modifying a discovery rule.

Our environment includes a Zabbix proxy performing the discovery scans, which may be relevant to the issue.

Thanks in advance for you assistance,

Eddie

Random Spikes in Utilization of configuration syncer worker internal processes

Desired — Tue, 15 Sep 2026 12:45:51 GMT

Hello there,

We recently made many of our core services highly available, zabbix server being one of them.
We're using a Patroni cluster of postgres databases behind a load balancer running on our Firewall.
This entails only one 'master' postgres server ever being read from and/or written to at any given time.
These database servers are running with SSD based storage behind them.

Zabbix was the first service we spun up to use this new Patroni cluster - previously we had a single Zabbix server v7.0.23 with a locally running MySQL backend (as opposed to postgres).
We had the same amount of hosts and general configuration from the old server, this recent exercise was really to just change to being highly available - not to change the overall host monitoring scheme or count.

This new postgres backend isn't being loaded/used-by any other services other than Zabbix at this time.
From my current research there are some suggestions this could be database slowness - though I've yet to confirm that is truly the cause and the spiking nature makes me dubious of that diagnosis.

For whatever reason we're getting random spikes of Utilization of configuration syncer worker internal processes hitting 100% for 17mins every occurrence.
The time between occurrences appears random and does not correlate with any other backend operations in our environment.

I'm attaching some graphs to show that on both HA Zabbix servers the spikes occur at the same time.
In addition is a last 7 days graph showing the inconsistency between occurrences.

I'm really stumped as to what's happening here.
Most of our hosts are Active Zabbix Agents (Linux, macOS, Windows), however the Windows Zabbix Agent Active template is the most used (by 317 hosts at this time).
I attempted to modify the template to bring the Windows services discovery to 6hr intervals rather than the default 1hr interval - but this really had no change on these spikes we're seeing.

Ultimately we're not seeing any performance or data gathering issues, but I'd like to address these spikes rather than just ignore them.

Here are some stats on our old and new server estates, do let me know if I can clarify anything further.

Zabbix queue backlog with IIS AppPool current queue size items

andrewkirwin — Tue, 15 Sep 2026 10:25:09 GMT

Zabbix Server: 7.0.17
Zabbix Agent 2 (Windows): 7.0.30
Client: Windows Server 2022 Standard
Template: IIS by Zabbix Agent (7.0-3)

Hi All,

I am experiencing an issue with the IIS by Zabbix Agent AppPool current queue size item getting stuck in the queue when the AppPool is stopped, or running but unassigned.

I have investigated the Zabbix Agent 2 logs on the client machine and believe I have found the culprit, but was wondering if anyone else has seen or been able to resolve this issue?

got nil value, skipping sending of response

I see this after the agent is queried for the AppPool current queue size of a stopped/unassigned IIS application on version 7.0.30 of the Windows client.

Rolling back to version 7.0.12 I get the below...

sending passive check response: '{"version":"7.0.12","variant":2,"data":[{value":null}]}' to 'PROXY-IP-REDACTED'

Suggesting a change in logic between the versions, where the older version sends a "null" value and the newer version doesn't send anything.

Sending nothing means the item sits in the queue on the server... waiting for a value... forever.

Thanks in advance for you assistance,

Andrew

Zabbix Agent VBScript Requirement Query (Agent Version 7)

MetrosWork — Mon, 14 Sep 2026 10:54:37 GMT

Firstly, thank you for any responses.

Zabbix agent version - All version 7 installers (zabbix_agent2-7.0-latest-windows-amd64-openssl.msi and zabbix_agent2-7.4.14-windows-amd64-openssl.msi
Error code - 2738
Error description - Installer has encountered an unexpected error installing this package
Error investigation - Error code linked to VBScript being disabled on the server

Investigation detail:
We have recently run into an error upon installing the Zabbix agent on a new CIS hardened Server 2025 image. In our estate, we have disabled VBScript as part of the hardened image. Upon Zabbix installation, it was discovered that it is using VBScript components during the install to function, leading to an unsuccessful install. For those not aware, Microsoft have released a roadmap where VBScript will eventually be turned off by default and then completely depreciated. Whilst we are ahead of the curve, we wanted to find out if there are alternative avenues to install the required agent, or if there is a Zabbix roadmap that will remove the VBScript component? Reinstalling the VBScript Windows component allowed Zabbix to successfully install, but we would ideally like to avoid this matter, especially when Microsoft will eventually remove it.
