Nagios XI Infrastructuring Monitoring Software

Nagios XI is an extensible (open source) IT network monitoring software. It allows network and system administrators to check on the health of their network—websites, servers, hardware, software, and any cloud-based resource.

The Nagios XI software is in use worldwide by airlines, biotech companies, defense contractors and systems, emergency services, energy companies, enterprise retailers, governments and other organizations that require high transactional speed and accuracy on load times and data exchanges.

Nagios XI can monitor the overall health of the network, as well as individual endpoints— network "objects" such as inventory application servers, temperature gauge data within a nuclear reactor core, an employees' work-issued mobile phones or point-of-sale credit card scanners used in department stores.


Transform a legacy, engineer-grown product to a "customer-first" strategy.


The client and tech support feedback from new users was that the redesigned system is easier to learn. Expert users found the navigation cleanup helpful, and was happy to see the Core Configurator (an expert component) remained largely the same, but with updated UI and visual design. The system had evolved, but based on the timeframe and budget, had not addressed the unmet needs of the most sophisticated clients.

  • Contextual Interviews
  • Customer and Tech Support Interviews
  • Heuristic Analysis (Global and Page-Level)


My understanding of network monitoring was somewhat limited going into the project, but after some exploration (see "IT Network Monitoring 101 Deck" in Artifacts below), things moved quickly and efficiently. The client was very focused on maturing the user experience, and was willing to adapt and rework as needed, so little stood in the way of designing better UX.

The client had well-documented data supporting the difficult onboarding of new users. Throughout all the redesign, we constantly evaluated what new users (compared to experts) with respect to navigation, help features, and primary, secondary and automated tasks. I created some archetypes (Learner, Legend and Legacy) to help us evaluate the test designs.

During the discovery phase, we received a lot of feedback from long-time users (Legacy archetype) concerning the system's ability to accommodate their size requirements. (As shown here , one 3,000-store grocery chain in Belgium said some reports and visualizations would take days to process, or be unable to be viewable at all.) We did have to report to the client the technology shortcomings, as well as refocus the conversations toward aspects we could improve in the information architecture / within project scope.


I'd primarily worked with the client strategist/subject matter expert and their Chief Technology Officer in daily work sessions. Other roles on the team included: UX Research Lead (myself), Information Architect (myself), Project Manager, IT Network Subject Matter Expert, Visual Designer.

Next Steps

  • Field Study
  • Tree Test Navigation
  • Reevaluate Frequently Used Dashlets (Embedded Components)
