Nagios XI and Zabbix compete in the monitoring tools category. Zabbix appears to have the upper hand with its extensive scalability, integration capabilities, and being cost-effective with no initial licensing fees.
Features: Nagios XI offers easy installation, support for various services out-of-the-box, and high customization through plugins. It is flexible and backed by strong user support. Zabbix provides extensive scalability, auto-discovery for multi-host monitoring, and detailed templates suitable for large environments with a strong open-source community.
Room for Improvement: Nagios XI needs better clustering and failover features along with improved configuration interfaces. High availability solutions are complex and not fully integrated. Zabbix could enhance its UI, reporting, and predictive maintenance. Pre-built templates for various devices and better documentation could improve usability, indicating where support could be better.
Ease of Deployment and Customer Service: Nagios XI is praised for straightforward deployment in on-premise environments, but installation complexity varies across Linux distributions. Technical support receives mixed reviews, balancing significant support experiences with costly licensing. Zabbix offers flexible deployment across multiple environments with wide community support and extensive documentation. Some users note challenges in complex setups.
Pricing and ROI: Nagios Core is free, but Nagios XI is a paid version with added features, sometimes seen as costly. Users suggest starting with low-cost options and scaling based on needs. Zabbix, as an open-source solution, incurs no initial licensing costs, offering cost-effectiveness. Users value the lack of hidden fees, making Zabbix attractive for enterprises needing extensive monitoring at no cost, despite optional paid support.
It is so straightforward that I have never had to use the support.
If the user interface isn’t presenting data well, it becomes difficult to manage when scaling.
Zabbix has high scalability.
Zabbix is very scalable and lightweight.
Zabbix is good and scalable, but not as fast as SolarWinds.
It is very stable.
Zabbix is very scalable and lightweight.
I think the stability of Zabbix is around five to six on a scale of ten, where ten is the best and one is the worst.
Zabbix is quite stable, and we haven't had any problems with Zabbix itself.
Many tools have poor user interfaces, making them hard to manage and navigate.
The GUI could be improved. It's a bit too basic.
The only issue I can note is that it's Linux-based, and Linux documentation is not the best.
The potential and customization is a little difficult because you have to learn scripts.
We are using the free, open-source version.
The pricing for the Nagios XI product is good and better than other solutions.
Zabbix is providing everything free of cost.
It is literally free.
Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.
The alerting system is very effective.
If disk usage surpasses a threshold, say 70%, I receive alerts and can take proactive action.
The alerting systems are very good in Zabbix, and it has helped us to reduce time for reaction.
People want to save costs, which is why they install Zabbix, but the reporting functionality is not properly developed.

Reviews from Real Users
Nagios XI stands out among its competitors for a number of reasons. Several major ones are its integration options and monitoring abilities, as well as its alerting features.
David P., a senior DevOps engineer at EML Payments Ltd, writes, “We use Nagios as a network discovery tool. We use Nagios to maintain our uptime statistics and to monitor our services. It has allowed us to be much more sophisticated in our monitoring and alerting.”
An IT-OSS manager at a comms service provider notes, “Nagios XI has a custom API feature, and we can expose custom APIs for our integration. This is a great feature.”
