Nagios Core and Zabbix are open-source IT infrastructure monitoring solutions. Nagios Core is a mature solution that focuses on flexibility in customization, timely alerts, centralized dashboards, and plugin support for versatile monitoring solutions. Zabbix offers comprehensive monitoring capabilities, customizable alerting, user-friendly interface, and extensive reporting.
Comparing the features of Nagios Core and Zabbix:
Pricing and ROI: Nagios Core and Zabbix are free and open-source. Zabbix's user-friendly interface and web configuration might reduce setup and maintenance costs for some. Conversely, Nagios Core's large community and extensive plugin library could minimize the need for paid support. Ultimately, ROI depends on your technical expertise.
Room for Improvement: Nagios Core reviews highlight the need for a more modern UI and easier configuration options. Zabbix reviewers mention occasional scalability limitations for extremely large deployments.
Customer Support: With an open-source model, both rely on community support forums for free assistance. Paid support options are available for Nagios XI and Zabbix enterprise versions, offering faster response times and dedicated help. Reviews suggest a slight edge for Zabbix's community support due to its larger user base.
Deployment: Zabbix offers a more straightforward installation process with a web-based interface for configuration. Nagios Core requires manual configuration through text files, although a web interface is available with the paid Nagios XI version. Both have good documentation, but Zabbix's web interface might be easier for beginners.
The summary above is based on 58 interviews we conducted recently with Zabbix and Nagios Core users. To access the review's full transcripts, download our report.
"We can manage the entire system across the network and troubleshoot the pain points."
"Nagios Core is stable."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"We use the product to monitor server applications."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"The application performance monitoring feature is valuable."
"I like the way the solution sends alerts and how it keeps on escalating them."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"It has improved our server performance monitoring overall. We know right away when there are problems. It has built-in statistics, so we can go back and see if there's spiking. We can check what's happening every day around the same time and check the configuration to see if there's something that's running and needs to be fixed."
"During my testing, the features that I like the most are that it can be integrated with my system, and it provides me with reports of all of my servers."
"There are lots of great features and functionality within the solution."
"I like being able to use proxy servers for different locations. The agents are pretty cool. They're easy to roll out. The standard out-of-the-box templates are also pretty easy to use. The integration with other learning products is also good. I have, in the past, used Slack, but we've integrated it with Microsoft Teams. We also use it for SMS with a service called Redcoat. It is very flexible. It does what I need it to do, and my manager is very happy because it doesn't cost anything. We are nearing 4,000 hosts inside Zabbix, and we've got another 6,000 access points to add to it. We've thrown everything at it, and it has managed to keep going. I am very impressed with the tool, and I'd shake their hand very hard if I got to say the compliments to the Zabbix team. They keep improving it and doing refreshes, which is one good thing about it. There is also online information as well as books that you can purchase if you're willing to read enough. There is a lot to pick up, but it is a pretty complete solution."
"It has good graphs of what is going on within the operating system."
"The most valuable features are the monitoring and the ease with which we can set it up at customer sites with our custom Zabbix proxy and tools."
"The template system in Zabbix is very beneficial as it saves time in configuration."
"Our customers also like that they don't have to use multiple modules. Micro Focus and major vendors typically require you to buy several modules and plugins. Our customers do not like that. We offer them a single product for all their monitoring needs."
"The Wi-Fi side needs improvement."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"The tool needs to improve the integrations."
"The initial setup process could be easier."
"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."
"The dashboard and monitoring features could be improved."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"The user interface could be more interactive because it is pretty basic."
"I am having difficulties connecting it to Grafana, as well as some of the other plugins like Kibana."
"The only improvement I would suggest, revolves around its AI and ML capabilities."
"In an upcoming release, there should be automated reports which we are currently doing manually. For example, if we collect a report file every day and want to send it to a moderator for review. We are expecting this feature to come out soon but it would be valuable to have now."
"Zabbix can use better documentation and support for troubleshooting."
"The user interface could be better."
"I want Zabbix to improve the UX/UI. Zabbix doesn't use a JavaScript chart for images, and I want them to improve this."
"The dashboard and the graph section could be a little bit more professional."
"Zabbix does not draw automatic mapping of the network, this is something they should add in the future. There is a lot of effort that is involved in tailoring some of the settings which could be made easier."
