Nagios Enterprises today announced the general availability of Nagios XI 2024R2.1, the latest update to its flagship IT infrastructure monitoring platform.
This release delivers vital security hardening alongside new SNMP management capabilities designed to improve large-scale network monitoring and reporting.
Strengthened Security and License Management
One of the headline enhancements in 2024R2.1 is the closure of a cross-site scripting (XSS) vulnerability in the Graph Explorer feature, which could have allowed attackers to inject malicious scripts via certain URL parameters.
The Nagios XI team credited security researcher Marius Lihet for responsibly disclosing the issue.
In addition, the release adds support for new license levels, enabling more granular control over user permissions and feature access within large enterprise deployments.
The update also removes support for Ubuntu 20.04 due to its end-of-life status, ensuring that customers are running on up-to-date, supported operating systems.
Administrators will need to plan migrations accordingly to maintain platform security and receive future updates.
Expanded SNMP Functionality
Nagios XI 2024R2.1 significantly enhances SNMP-based monitoring workflows.
A new “SNMP Walk Jobs” page allows users to manage and execute SNMP walks independently from the Wizard interface, improving the scalability and reliability of large device audits.
Under the hood, the SNMP Walk Wizard has been updated to utilize jobs created by this new page, while step 2 of the wizard now supports MIB grouping and “select all” functionality for faster configuration of hundreds of OIDs.
In addition, administrators can now integrate Nagios Mod-Gearman to offload event processing and distributed checks, which helps large deployments maintain high performance under heavy loads.
The Nagios Core version bundled with this release has also been updated to 4.5.9, bringing the latest performance optimizations and stability improvements.
