6. Mod Gearman Is Now Officially Supported
One of the most significant additions in Nagios XI 2026 is the official support for Mod Gearman, Nagios’ long-standing distributed job-processing plugin.
What Is Mod Gearman?
Mod Gearman allows you to offload checks from the main Nagios XI server to one or more remote workers (also called “gearman workers”). This enables distributed load processing — perfect for large environments or multi-site monitoring setups.
Why This Matters
Until now, Mod Gearman was community-maintained and required manual integration. In XI 2026, Nagios has:
- Fully integrated Mod Gearman into the Core Config Manager (CCM) and Admin GUI.
- Added a setup wizard for distributed worker nodes.
- Included pre-built configuration templates for worker and server nodes.
- Ensured full compatibility with Smart Dashboards and XI reporting modules.
Benefits
- Performance boost: Offload thousands of checks from the central XI server.
- Better scalability: Easily monitor remote networks or large enterprise infrastructures.
- Simplified management: Manage distributed nodes directly within Nagios XI without custom scripting.
With Mod Gearman officially supported, Nagios XI 2026 now scales far beyond traditional single-node limits — making it an excellent fit for organizations that need enterprise-grade distributed monitoring.
Security and Maintenance Updates
- Fixes for critical vulnerabilities, including a remote command execution issue and several injection bugs in older wizards.
- Enhanced compatibility between Smart Dashboards and the latest Neptune UI theme.

Final Thoughts
The Nagios XI 2026 release represents a thoughtful step forward — refining usability while expanding scalability.

If you’ve been waiting for a version that combines enterprise-level scaling with friendlier day-to-day management, Nagios XI 2026 is the upgrade to make.
