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

Zweep: A self-hosted Android alerting solution for Zabbix

Nicodroid — Wed, 07 Oct 2026 14:24:20 GMT

Hi everyone,

while looking through the community for existing solutions to manage Zabbix alerts from mobile devices, I found several interesting options, but none that fully matched what I was looking for.

So, over the past few weeks, I started working on Zweep, an open-source, self-hosted alerting system for Zabbix, with an Android app for receiving alerts, viewing active problems, and acknowledging them directly from the phone.

The idea came from a practical need: being able to receive Zabbix alerts without relying on third-party cloud services, using a channel dedicated exclusively to Zabbix rather than mixing these notifications with those from other services.

The basic flow is:

Zabbix Action → Zweep media type → Zweep server → Android app

The main goals are:

keeping alert delivery completely self-hosted;
avoiding Firebase/FCM and other third-party notification services;
not storing Zabbix credentials on mobile devices;
allowing operators to view and acknowledge problems directly from the app (which can also be useful for quickly stopping an escalation);
leaving recipients, retries, timing, and escalation logic to Zabbix Actions.

I’m aware that Zabbix has announced an official mobile app. Zweep is not intended to replace it or compete with its broader features. The goal is rather different: to provide a completely self-hosted alert-delivery system that can continue working even without Internet access (as long as the Zweep server and the devices can reach each other over the internal network). The app also makes it possible to quickly keep track of notifications and the problems that generated them, without having to open the full Zabbix dashboard every time.

For transparency, my professional background is mainly in systems administration, networking, and Zabbix rather than software development. Zweep started from a real operational need, and I developed it iteratively with significant help from AI-based coding tools.I’ve reviewed and tested the project’s behaviour and added automated tests, security checks, dependency scanning, and an SBOM. I’m sharing the project because I think there may be similar use cases where it could be useful.

If anyone would like to try it in a lab environment, I’d be very interested to hear what works, what doesn’t, and what you think could be improved.

The project is available on GitHub:

Thanks for taking a look!

"Proxmox VE by HTTP" duplicates alarm on storages.

Pigi_102 — Wed, 07 Oct 2026 06:57:32 GMT

Hello all,
I have a three nodes cluster where, among most other external storages, I have a local zfs storage on every node.
One of three nodes have this local storage almost full while others have it fine ( but I think this also happens on external storages).
So, to better explain, this is the situation:

Code:

=== Storage of: pve1 ===
LocalZfs: Total=67GB, Used=61GB, Free=7GB (Active: 1)

=== Storage of: pve2 ===
LocalZfs: Total=67GB, Used=3GB, Free=65GB (Active: 1)

=== Storage of: pve3 ===
LocalZfs: Total=67GB, Used=3GB, Free=64GB (Active: 1)

This should lead to an error on only pve1 but instead:

Is this something that could be corrected In someway ?
Who should I ask, eventually ?

Thanks in advance

Allow setting mysql connection Options

cbergmann — Tue, 06 Oct 2026 14:26:47 GMT

Hi,

we are using the PAM module for authentication against our MariaDB cluster.
We also want to monitor that authentication with Zabbix.

Unfortunately this seems to be impossible.
At first we got the error "this authentication plugin is not supported". This is because by default the PAM module for mariadb uses the dialog authentication plugin which is not supported by go-sql-driver. After adding "pam_use_cleartext_plugin" to the mariadb config it now uses the "mysql_clear_password" authentication plugin. Unfortunately enabling this requires setting "allowCleartextPasswords=1" in the DSN. But I found not way of passing this DSN parameter through the zabbix agent.

If there is a way I could not find it would be highly appreciated.

kind regards
Clemens

Unsupported DB! timescaledb version 23002 is newer than 22999

splarv — Tue, 06 Oct 2026 12:09:56 GMT

Hi all.
We use Debian 13.7 and PostgreSQL from the Debian PGDG repository. There are TimescaleDB in the PGDG repository with versions: 2.30.0+dfsg-1.pgdg13+1, 2.30.1+dfsg-1.pgdg13+1, 2.30.2+dfsg-1.pgdg13+1. There is not 2.29 version. Zabbix used from the zabbix repository:
http://repo.zabbix.com/zabbix/7.4/stable/debian

The problem is:

983233:20261006:150005.457 using configuration file: /etc/zabbix/zabbix_server.conf
983233:20261006:150005.472 Unsupported DB! timescaledb version 23002 is newer than 22999
983233:20261006:150005.472 TimescaleDB version is too new. Recommended version is up to TimescaleDB Community Edition 2.29.
983233:20261006:150005.474 Zabbix Server stopped. Zabbix 7.4.15 (revision bd350f540cd).

Why do you artificially restrict to 2.29? 2.30 is the minor version upgrade so it is will work with 2.30 too. May be you want to guarantee zabbix working, but you measures guarantee only that zabbix will not working. Now I have to drop database and recreate without TimescaleDB, this is not good.

There is a way to change the database failure message?

galavichid — Mon, 05 Oct 2026 19:57:40 GMT

I have few Zabbix servers, all using same smtp relay for sending e-mail notifications. Last week, I had failure in one of them, but I need to check first which one isn't instead just see it from the e-mail I got.

There is a way to change the message so I can make it more specific?

The message:

MySQL database "zabbix" on "localhost" is not available: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Thanks

How can I monitor an on-premises ESXi host using Zabbix Cloud?

jmmalbas — Fri, 02 Oct 2026 16:31:29 GMT

Hi,

We are an MSP provider and have Zabbix deployed in the cloud, running the latest version, 7.4.13.
We would like to monitor our clients’ ESXi hosts using our centralized Zabbix server. Is this possible?

It looks like Zabbix Agent 2 is not available for installation on the ESXi operating system. What would be the recommended approach for monitoring ESXi hosts with Zabbix, especially when the Zabbix server is hosted in the cloud and the ESXi hosts are located at different client sites?

Any recommendations or guidance would be greatly appreciated.

Thank you!

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

Proxmox VE by HTTP (8.0.0rc1): hardcoded 10m/10s on per-disk "Get info" causes issues

broth-itk — Thu, 01 Oct 2026 22:31:26 GMT

Dear Zabbix team,

in the "Proxmox VE by HTTP" template (8.0.0rc1), the item prototype Node [{#NODE.NAME}]: Disk [{#DISK.NAME}]: Get info has a hard-coded update interval of 10m and a timeout of 10s. The existing macro {$PVE.PARAMS.INTERVAL.DISK} (1h) is only used by the Disks discovery rule, not by this prototype.

Every disk gets its own item that requests the same URL, /nodes/{#NODE.NAME}/disks/list, and extracts its own entry by JSONPath. On a node with 58 disks, that is 58 identical requests every 10 minutes. On my node a single pvesh get /nodes//disks/list takes 14s (about 5.6s CPU), so every request runs into the 10s timeout, and the dependent items (Model, Serial, Type, Vendor) go unsupported. In addition, the constant stream of these requests keeps the node busy permanently. The discovery rule and SMART status also use the hard-coded timeout of 10s.

Suggestions:

A) Quick fix: change the hard-coded values to {$PVE.PARAMS.INTERVAL.DISK} (1h) and a timeout of 60s. Static data like model and serial does not need a 10m interval, and it matches the SMART interval.

B) Add macros for the interval and the timeout (e.g. {$PVE.TIMEOUT.DISK}), so they can be adjusted per host without cloning the template.

C) Cleaner: let the discovery rule (which already fetches /disks/list) or one master item per node fetch the list once, and make the per-disk items dependent items with JSONPath. That replaces N redundant requests with one and avoids the timeout problem entirely.

Happy to test any of these on my setup. Keen to hear your thoughts.

Best regards,
Bernhard

Windows Event Log Unique Triggered Problems

jwrober — Thu, 01 Oct 2026 17:48:21 GMT

Hi all, I'm new to Zabbix. I'm running a newly installed v7.4.15 setup on a CentOS Stream 10 Linux VM. I am wanting to use the windows agent to capture windows event logs. In the "Windows by Zabbix Agent Active" template I have created 3 new items with the following code:

Code:

Name: Application Event Log Events (Critical/Error/Warning)
Key: eventlog[Application,,"Critical|Error|Warning",,,,skip]

Name: Security Event Log Events (Critical/Error/Warning)
Key: eventlog[Security,,"Critical|Error|Warning",,,,skip]

Name: System Event Log Events (Critical/Error/Warning)
Key: eventlog[System,,"Critical|Error|Warning",,,,skip]

I then created three triggers to log problems on the console:

Code:

Name: Windows: Event Log: Application (Critical / Error / Warning)
Expression: length(last(/Windows by Zabbix agent active/eventlog[Application,,"Critical|Error|Warning",,,,skip]))>0
Ok Event Gen: None
Problem Event Gen Mode: Single
Allow Manual Close: Yes

Name: Windows: Event Log: Security (Critical / Error / Warning)
Expression: length(last(/Windows by Zabbix agent active/eventlog[Security,,"Critical|Error|Warning",,,,skip]))>0
Ok Event Gen: None
Problem Event Gen Mode: Single
Allow Manual Close: Yes

Name: Windows: Event Log: System (Critical / Error / Warning)
Expression: length(last(/Windows by Zabbix agent active/eventlog[System,,"Critical|Error|Warning",,,,skip]))>0
Ok Event Gen: None
Problem Event Gen Mode: Single
Allow Manual Close: Yes

The challenge I have is I am getting problems for new log events associated with closed/resolved problems. Here is a sample. The original event was for a DLL not have perfmon data. I acknowledged it with some update entries

and closed. Then today it "came back" with this new event that isn't a repeat of the first one.

Is there a way to change the trigger to add some kind of unique values to the problem so as I resolve things Zabbix finds, it doesn't bring back old problems as new?

Thanks in Advance

problems with SNMP Bulk Request - bits send/received in Dependent Item

daniel.ramirez — Thu, 01 Oct 2026 16:46:34 GMT

i have a rare problem with data collection from SNMP Bulk Request.
this is Master Item:

and this is dependent item:

the dependent item sometimes do not poll on the configured time (5 minutes in the master item) and this produces strange peaks in values:

value table:

in the last polling, it tooks 9 minutes to poll a new value, after that only took 1 minute and generate that strange value (400Gb aprox.)

what could it be causing this behavior?

PD: the proxy is stable with normal vps and no queued values.

Can I apply a template to multiple hosts I have already discovered?

John_W — Thu, 01 Oct 2026 15:18:08 GMT

I don't see a way to assign a Template in the Discovery Rule. I can manually add the template after discovery, but that can take up some time, depending how many hosts I discover.
