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."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"We use the product to monitor server applications."
"I like the way the solution sends alerts and how it keeps on escalating them."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"Nagios Core is very configurable. Whatever you want, you can do it."
"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."
"The most valuable feature is the performance parameters of the system."
"We use Zabbix to monitor our organization's IT infrastructure and workstations. We don't use Microsoft Intune since it's expensive. The tool's real-time alerting system has proved crucial for us, particularly when a new device joins a network that is not one of our own devices. It notifies us about the presence of this new device, allowing us to investigate further. Additionally, it alerts us about disk usage, memory usage, and the software installed on the machine."
"Its overall flexibility is most valuable. When our customers have some custom applications that are not necessarily covered by the community or a standard monitoring tool, we use Zabbix to build our own modules with our own templates. This feature has been useful in using Zabbix for infrastructure and IT monitoring. It has also been useful for industrial equipment monitoring. Zabbix is very lightweight. It is efficient in terms of performance because it doesn't use a lot of resources."
"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."
"The solution is stable."
"It's a flexible solution."
"Zabbix is a cost-effective solution. We're a small organization with a few dozen devices to monitor, and it was available for free. We can see what we need. We haven't done an in-depth analysis on it, but we're currently okay with the product."
"I'm supervising all the IT departments, and Zabbix seems quite good for them. It provides graphics and information in real time. We get alerts about crashes on the system, enabling us to quickly repair issues. We can easily find devices with problems."
"It has good graphs of what is going on within the operating system."
"The Wi-Fi side needs improvement."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"The tool needs to improve the integrations."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"The mapping is a little hard."
"The UI is a little outdated and graphics could be displayed in a better way."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"We had some scalability issues with a large number of nodes."
"In the next release, I'm hoping for features targeted towards larger users with more customizable options. Despite this, I think pre-canned reports that can be used straight out of the box would be beneficial rather than having to configure each report individually. Additionally, a deeper dive into software configurations on the machines would be useful, although I understand there may be challenges in implementing this due to scripting requirements. More documentation would also be appreciated."
"Look and feel."
"When using this solution in enterprise monitoring, you are able to see that there are some issues with equipment that could be causing a problem. Sometimes you want to make a root command that you do not want to be executed automatically. What we have tried to do is open an SSH session directly from the solution's interface but it is not possible."
"They should open an SSH session from the web interface."
"One of the things we don't like is that Zabbix has a license structure with a price that is high compared to the competition. It's very high, for example, compared to something like Microsoft Teams."
"I think the reporting part of Zabbix can be improved in terms of more user-friendly graphics to display the collected data. Many simple users who don't know how to use Zabbix properly might get confused by the reporting, although at the same time it is very versatile for my company."
"The performance reporting could be improved."
