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."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"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."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"The solution is quite efficient."
"Nagios Core is stable."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"We use the product to monitor server applications."
"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."
"The initial setup was very quick. The first time it was long because I didn't know it yet. I was only using Windows. The first time was very difficult because of the operating system."
"We are able to do problem determination on runaway processes."
"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."
"Zabbix can use old data to current data to set the threshold. We can use previous data to set the threshold."
"It meets my organizational needs. It's pretty easy to use."
"The overall functionality of Zabbix is very good. The monitoring of bank applications that Zabbix provides is great. The information is displayed on a dashboard that is easily viewed."
"The flexible licensing model is one of the solution's most valuable aspects. It really allows for great flexibility for companies."
"The most valuable feature is monitoring."
"The Wi-Fi side needs improvement."
"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"Would benefit from aggregations if a particular server goes down."
"The UI is a little outdated and graphics could be displayed in a better way."
"It is a bit slow due to latency."
"The core version is no match for the XI version."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"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."
"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."
"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."
"The solution needs to add remote features."
"For us, the initial setup was complex"
"The stability could be better."
"The performance reporting could be improved."
"As far as improvements, sometimes I get a bit frustrated when I move from a previous version to a new one because some configuration has changed—I need to investigate the documentation to deal with some configuration. But it doesn't take much time, so it's okay."
"Zabbix is not easy to configure, and upgrading is also an issue."
