openITCOCKPIT version 5.6.0 has been released! Packed with new features, such as support for Proxmox VE, a new parent-child relationship tree, support for the latest Linux distributions, security updates and much more.
Import Module: Proxmox VE
The Import Module now supports Proxmox VE as a data source. This allows you to easily import all virtual machines and LXC containers from Proxmox VE into openITCOCKPIT for monitoring. openITCOCKPIT will automatically create services for all VMs and containers to keep an eye on CPU, memory, disk usage (LXC only), network traffic and more. No modifications or agents are required as openITCOCKPIT will use the Proxmox API to query all the necessary data.
In addition, hosts that are imported from Proxmox, will have a new Tab in the host details view named Proxmox VE. This tab will provide an overview of the VM or container and provides access to actions such as start, stop, restart. It is also possible to create or rollback snapshots, as well as to open the Proxmox VE web interface directly from openITCOCKPIT.
Please see the docs for more details: https://docs.openitcockpit.io/en/configuration/import-module/#proxmox-ve
Checkmk update to 2.4.0p30
We decided to upgrade the integrated Checkmk version to Checkmk Raw Edition 2.4.0p30.
This update will probably cause some issues and requires manual adjustment due to breaking changes. Please consider this before running the update.
Most issues could probably fixed, by rediscovering Checkmk services with the following command:
oitc CheckmkModule.service_discovery --dry-run
With the --dry-run parameter, the command will ony print the changes that would be made, without actually applying them. This allows you to review the changes before they are implemented.
To apply the changes, simply remove the --dry-run parameter.
It is also possible to filter for specific check types to a host IDs like this:
oitc CheckmkModule.service_discovery --dry-run --check-filter if64 --check-filter lnx_if --host-id 1 --host-id 2
Known Issues
Checkmk changes the syntax of some check parameters from time to time which will cause issues like check failed - please submit a crash report! (Crash-ID: 39acbedd-0dd5-4192-b19d-8ea8550daac0).
If you encounter such an issue, the best way to fix it, is to delete the affected services and rediscover them again. It could also be required to delete the service template.
Please follow our documentation on how to create custom service templates: https://docs.openitcockpit.io/beginners/monitoring-checkmk/#fehlende-servicevorlagen-fur-checkmk-erstellen
Known affected check types are:
- Fortigate
- APC (UPS)
- HP iLO
For example:
OLD: fortigate_sessions_base None, (100000, 150000)
NEW: fortigate_sessions_base None {'levels': (100000, 150000)}
New Parent Child Relationship Tree
The relationship between parent and child hosts will now be displayed in the detail view of a host as tree structure.
Support for Ubuntu 26.04 and Enterprise Linux 10.2
With openITCOCKPIT 5.6.0 we are now supporting Ubuntu LTS 26.04 (codename “Resolute Raccoon”), as well as the latest Enterprise Linux releases, such as AlmaLinux 10.2 (codename “Lavender Lion”), Rocky Linux 10.2, Red Hat Enterprise Linux 10.2 and other RHEL compatible clones.
Drop support for Ubuntu 22.04
openITCOCKPIT 5.6.x will be the last release to support Ubuntu 22.04 (Jammy Jellyfish). This step is necessary as Ubuntu 22.04 uses PHP 8.1, which does not receive security updates for more than 6 months now.
Please update to Ubuntu 24.04, the process is well tested and documented: https://docs.openitcockpit.io/en/update/ubuntu-jammy-to-noble/
With openITCOCKPIT 5.7.0 Ubuntu 24.04 will be the minimum required version.
Drop support for Debian Bookworm
openITCOCKPIT 5.6.x will be the last release to support Debian Bookworm (12) due to Debian 12 has reached its end of regular security support in June 2026.
Please update to Debian 13, the process is well tested and documented: https://docs.openitcockpit.io/en/update/debian-bookworm-to-trixie/
With openITCOCKPIT 5.7.0 Debian 13 will be the minimum required version.
Drop support for PHP 8.1
openITCOCKPIT 5.6.x will be the last release to support PHP 8.1, as it has reached its end of life.
This change will only affect users of Enterprise Linux (such es Red Hat Enterprise Linux, AlmaLinux, Rocky Linux, etc.). Users of Ubuntu and Debian are not affected by this.
With openITCOCKPIT 5.7.0, PHP 8.3 will be the minimum required version. You can already update to PHP 8.3 on Enterprise Linux today.
Assuming you are using Remi’s RPM repository, the update process is as simple as running the following commands:
dnf --refresh check-update
dnf update
dnf module switch-to php:remi-8.3
Security Update: MapModule
The MapModule was affected by multiple security vulnerabilities. One of the vulnerabilities enables an attacker to delete files on the server. Only files where the web server user (www-data) has write permissions were affected.
Another issue was, that the MapModule did not properly check the user container permissions under all circumstances. So a user could access maps they should not have access to.
Also background images are now bound to the container permissions. #1795
New Wizards
We are still following our mission to provide many pre-configured monitoring templates for a wide variety of applications, databases, and hardware. In this release, we have added a number of new Wizards:
- Raritan KVM
- SonicWall
For a quick overview of the available metrics openITCOCKPIT can monitor, please see our metrics page.
Updated translations
openITCOCKPIT is available in multiple languages. Unfortunately, we do not have native speakers for all languages, so we rely on the community to help us with translations. In case you want to contribute, please see our translation guide.
To fill in the gaps, we used AI to generate some of the missing translations. We know that AI translations are not perfect, so if you find any issues, please let us know or even better, contribute a fix 🙂.
