NetEye 4.42 Release Notes
Welcome to version 4.42 of our NetEye v4 Unified Monitoring Platform.
Summer has arrived on the Seiser Alm, and with it, clear views of two of South Tyrol’s most iconic peaks: Langkofel (Sassolungo) and Plattkofel (Sassopiatto). From the trails that wind across the plateau, hikers can reach the summit cross of Sassopiatto at 2,964 meters, where a wide-open view of the Dolomites awaits, from the Sella Massif to the Marmolada, and even the lesser-known Grohmannspitze and Fünffingerspitze.
Security enhancement
Brute Force Protection
NetEye now includes enhanced security measures with the activation of brute force protection in the login process. This feature mitigates potential threats by limiting multiple failed login attempts, thereby safeguarding user accounts from unauthorized access attempts.
Enabling the Content-Security-Policy headers for IcingaWeb2
Starting from NetEye 4.42, all NetEye modules fully support strict CSP headers, providing stronger protection against XSS attacks. To take full advantage of these security enhancements and ensure a smooth transition to future releases, admins have to enable the CSP header and update their modules during this release cycle. Detailed instructions can be found in the NetEye Upgrade User Guide.
General
MariaDB Galera cluster
In this release, we are excited to introduce a clustered solution for MariaDB, namely MariaDB Galera, aimed at enhancing the high availability of all NetEye services. This improvement ensures that as the availability of the MariaDB database increases, so too does the reliability of all dependent services, such as Icinga2, IcingaWeb2, Grafana, Keycloak, and others.
With this change, we significantly reduce database downtime. Unlike previous versions of NetEye, which relied on a single instance of MariaDB, the new setup allows multiple MariaDB instances to work collaboratively, thereby providing a more robust database service.
For further details on this feature, please refer to our upgrade guide.
New User Guide
We’ve completely restructured and restyled the NetEye documentation to offer a more intuitive, use-case-driven experience. The new guide starts from real-world scenarios and then dives into the technical details, making it easier for both beginners and experts to navigate and apply. This release introduces a fresh layout and clearer chapter organization focused on practical usage.
With this new structure, we also reorganized the Elastic Stack module (previously known as the SIEM module) into a more coherent and accessible format. Additionally, we’ve added the Reporting module to the guide to provide complete and up-to-date coverage of NetEye’s capabilities.
Please take a look at the NetEye Guide Home Page to explore the new structure and discover how it can support your daily work with NetEye.
Note: Due to the documentation refactoring, some URLs have changed. As a result, links from older versions or external sources may no longer be valid.
Deprecation of the NetEye RPM Mirror
NetEye 4.42 deprecates the NetEye RPM Mirror, which will be removed in a future release.
Monitoring
Upgrade of Director to version 1.11.3
With this release, we continue improving the Icinga Director.
In order to improve the UX of the Director module, custom variables inside Host/Service overview page are now grouped by type and also collapsible: this should drastically improve the experience when hosts have many different custom variables assigned.
Additionally, version 1.11.3 addresses various key issues and brings many improvements to enhance stability and usability.
For a full list of changes, please refer to the official release notes.
Tenant Segregation for Icinga2 MariaDB Data
Grafana dashboards provide users with an intuitive way to visualise Icinga2 monitoring data. However, in multi-tenant environments, users from different tenants have previously faced challenges, as the Icinga2 monitoring data could not be segregated to ensure that each tenant only accessed their own information.
The release of NetEye 4.42 effectively addresses this limitation by automatically generating a dedicated view of the Icinga2 monitoring data for each tenant. Additionally, it provides a ready-to-use Grafana data source for each tenant, enabling tenant users to construct and visualize their own dashboards with ease.
NetEye Elastic Stack
Elastic Stack Update
NetEye 4.42 has upgraded its Elastic Stack from version 8.17.6 to version 8.18.1, allowing all SIEM and Observability users to take advantage of the latest features, performance improvements, and bug fixes.
For a deeper understanding of the new capabilities and improvements introduced in Elastic Stack 8.18.1, please refer to the official blog post. A full list of feature enhancements, fixes, and other changes can be found in the official release notes.
Renaming of the NetEye Elastic Stack Feature Module
We are updating the naming of one of our key feature modules: going forward, we will refer to it as the NetEye Elastic Stack, rather than SIEM, to better reflect the full set of capabilities it offers. This module includes both Elastic SIEM and Elastic APM functionalities, which are part of the broader Elastic Stack available in NetEye. To align with this wider scope, we have introduced a new feature module called neteye-elastic-stack, replacing the older and more narrowly named neteye-siem module. The new name provides a clearer understanding of the complete Elastic Stack available in NetEye. While neteye-elastic-stack is now the recommended module, the legacy neteye-siem module will remain available for a limited time to support a smooth transition. It is now deprecated and will be removed in a future release, giving users time to adapt to the new naming convention. You can find more information regarding this in the NetEye Upgrade User Guide.
