Nagios XI 2012r2.0 Now Available

We are pleased to announce that Nagios XI 2012r2.0 is now available. As an ongoing commitment to our customers, this release includes numerous small bug fixes, improvements, and new features to extend upon the most powerful IT infrastructure monitoring solution on the market.

This release includes an upgrade to Nagios Core 3.5.0, which contains bug fixes and updates related to downtime, restarts, and the way non-ASCII characters are handled. To learn more about the changes included in Nagios Core 3.5.0, you may view the changelog here.

Also included in XI 2012r2.0 is an upgrade to NDOUtils 1.5.2, which includes updates to address the effects that low system resources can have on database communications. Read more about NDOUtils 1.5.2 here.

A new feature included in this release is the ability to display a custom logo in your exported reports. In past versions, reports displayed the Nagios XI logo by default, but now with the use of the custom logo component, you may display a logo of your choosing.

An additional feature now allows host aliases (descriptions) to be searched via quick find.

Lastly, as part of this release, XI is now compatible with PHP 5.4.

We greatly appreciate the feedback that the Nagios community continues to provide. If there is a feature you would like to see in a future release of Nagios XI, be sure to share your ideas with our tech team in our Nagios Ideas forum!

Nagios SNMP Trap Interface – NSTI v2.0

NSTI version 2.0 has officially been released.  After a lot of hard work, and many feature-rich additions, the Nagios SNMP Trap Interface has been overhauled to include some major performance increases and greater ease-of-use.

The User Interface has been reimagined and streamlined to make exploring and managing SNMP traps much easier.  The functionality of NSTI 2.0 is not hidden within various menus, but exposed on the main GUI to reveal the capabilities of NSTI.  This allows you to parse through streams of SNMP traps more quickly and efficiently.

NSTI Interface

While creating a more straight-forward version of NSTI, advanced functionality was not forgotten.  NSTI 2.0 provides users with a dedicated screen for each trap that presents all of the data that has been captured from that trap.  This allows for the advanced trap information to be accessed easily without cluttering the main NSTI page.

SNMP Trap Information - NSTI

Improvements have also been made to NSTI’s ability to integrate with existing Nagios XI implementations. Integration with Nagios XI makes it easier for system admins to manage and stay on top of SNMP trap information.

  • NSTI now has the ability to write SNMP trap information directly to the Nagios XI server.  This allows checks to be made for unread SNMP traps, and for admins to be alerted to traps based on their status (Critical, Warning, Unknown).
  • Previous SNMP trap management within Nagios XI only showed the last trap that was received, but now NSTI allows you to view all old traps and let the Nagios server know which ones have yet to be read.  This assists the user in keeping track of all historical SNMP trap data.
  • Another major improvement made to NSTI is its ability to force hostname information and sync it with the Nagios XI server.  This allows admins to easily correlate SNMP trap information with the corresponding host on the network, and eliminating tedious sorting of traps and crucial information falling through the cracks.   NSTI Hostname Integration

Nagios XI 2012r1.4 Improvements

With each new version of Nagios XI, we do our best to include the most important bug fixes, improvements, and features that we can accomplish in a few weeks time. The upcoming Nagios XI 2012r1.4 is going to be a notable release of XI for both performance improvements and internationalization.


For our international users, we’ve been hard at work to update XI appropriately for internationalization, as well as kick-starting multiple translations using Google translate. We’ve been working to balance code updates with community contributions for languages, and this upcoming release will ship with a default.pot file that can be used to update user’s PO files that they may have begun populating. This release of XI will ship with kick-started translations in the following languages.

  • German
  • Spanish
  • French
  • Italian
  • Portuguese
  • Russian
  • Korean
  • Chinese

Performance Improvements in 1.4

For customers with larger installs, we’ve been analyzing bottlenecks in both the monitoring process and the UI to try and make XI run faster and leaner. Users with hosts+services in the thousands will almost certainly see an improvement both in CPU load and page load times in the UI. For changes that affect the monitoring process, we updated the Monitoring Engine Event Queue dashlet and the Monitoring Engine Check Statistics Dashlets to all pull data from the same status information that the rest of XI uses, which reduces an enormous amount of data from needing to be logged to mysql from the monitoring process. The end result of this change is that mysql will only need to be doing about 30% of the work that it was having to do in previous releases. For large installs, this is a big deal!

The other key change that all users will probably see a benefit from is a refactoring of data queries for AJAX loaded content in the XI interface. Load times for dashlets that contain tactical or summary data went from 15-20 seconds per dashlet down to .05 seconds in local tests with 10k checks. The other upside of this change is that the CPU usage from XI users accessing the interface is substantially reduced. The Tactical Overview dashlets see the largest benefit in load times by far. For users who had to utilize the unified Tactical Overview for performance reasons, we encourage you to try the dashlet version in 1.4.

We hope to have 1.4 ready to release sometime this week, we appreciate our community of users and the feedback that we continue to get for our product. Thanks for helping us make XI better!
