Nagios Core Reviews Summary
Author infoRatingReview Summary
Senior System Administrator at Interactive Group5.0I've been a senior system administrator using Nagios Core for over a decade to monitor everything from databases to application servers. Its simplicity and comprehensive features, including configurable alerts and dashboards, make it an effective IT monitoring solution.
Tech Lead at STL Digital Limited3.5I use Nagios Core to monitor over 2,500 services and devices, finding its extensibility valuable, though its UI needs improvement. I recommend better integration and reporting features, considering alternatives like Zabbix and Grafana for superior visualization.
Senior application performance monitoring and alerting specialist at a transportation company with 1,001-5,000 employees4.0We use Nagios Core for internal system monitoring, valuing its backend capabilities. However, I prefer Zabbix for its scalability and full solution benefits. Nagios lacks advanced dashboarding, so we integrate its data into tools like Grafana for presentation.
Manager, IT at kas4.5I use Nagios for network monitoring, receiving alerts for device status via email or SMS. It effectively monitors disk space, processor usage, and temperature. However, the interface could be improved. I haven't considered alternate solutions or cloud providers.
Sr. System Administrator at Guj Info Petro Limited5.0I use Nagios Core for cost-effective infrastructure monitoring, offering extensive plugin support and strong community backing. Despite needing shell-based configuration, its reliability over many years significantly saves costs compared to paid monitoring solutions.

Administrator at self-employed4.5I use Nagios Core to monitor the network and some servers. Its most valuable feature is the alerting capability, which required customization and automation to work effectively. My company also utilizes Elastic, Grafana, and Kibana, seeking integration within one interface.
Regional Portfolio Manager at First in Business Solutions5.0I mainly use Nagios Core for monitoring servers and services, both inside and outside our network. Its notifications are valuable, but it could improve in graphics and usability. Previously, I used Centreon, which had a nicer interface.
