|---|---|---|
| Network and Security Engineer at a educational organization with 1,001-5,000 employees | 3.5 | I use Nagios XI mainly for monitoring server performance like CPU and memory. It's easy to install compared to other solutions, saving setup time. However, its user interface needs improvement. I considered Grafana and Libre NMS as alternatives. |
| Site Duty Manager at Assw | 4.0 | We use Nagios XI for network and server monitoring, appreciating its effective alerting system and useful features like JPS Web. Although we love it, the GUI could be improved. We've also considered alternatives like Zabbix and ScienceLogic. |
| Assistant Director at unpa | 5.0 | I find Nagios XI excellent for monitoring IT infrastructure, being very stable and scalable. While deployment can be complex for some and more integrations would be nice, I rate it highly for its effectiveness and features. |
| Senior DevOps Engineer Individual Contributor at EML Payments Ltd | 4.0 | I value Nagios XI for stable, scalable on-premises network monitoring and good ROI. However, its public cloud limitations mean I won't extend it to my hybrid cloud strategy, seeking alternatives there. |
| Solutions Architect at NTT | 3.5 | No summary available |
| Manager, Information Technology Monitoring at a tech services company with 201-500 employees | 3.0 | We primarily used Nagios XI to monitor Linux servers and scripts due to its simplicity and ease of use. However, we faced issues with graphics and scalability, found it expensive, and ultimately preferred Checkmk for its stability and affordability. |
| DevOps consultant at Africa4Data | 4.0 | I find Nagios XI beneficial for its numerous plugins and scripts that enhance monitoring capabilities. However, it lacks SAP monitoring and a built-in dashboard, requiring manual database connections for creating visuals, which is a drawback. |
| Senior Analyst at a tech vendor with 10,001+ employees | 4.5 | I use Nagios XI for infrastructure and application monitoring, finding its customization feature valuable for tailoring to specific needs. However, improving network and hardware monitoring and adding automatic reporting would enhance its effectiveness. The solution is stable overall. |
