Nagios vs Zabbix – What’s the Difference ? (Pros and Cons)
Nagios vs Zabbix – What’s the Difference ? (Pros and Cons). Here we talk about two programs. Nagios monitors networks, network devices, applications and servers running on Linux and Unix distributed under the GPL license. Well, hosts and services are monitored according to specific settings, so you customize it to fit your needs. One of the other solutions is Zabbix. An open source software tool for monitoring IT infrastructure such as networks, servers, virtual machines and cloud services.
Shell we start with Nagios vs Zabbix – What’s the Difference ? (Pros and Cons).
What is Nagios?
Once again, we are dealing with open source software, and Nagios purpose is aimed at monitoring computer systems. In addition, it is run on the Linux operating system, precisely for the purpose of monitoring devices that are executed on Windows, Unix and Linux operating systems. Its main task is to constantly check key server resources, applications, networks and tasks.
Also, it monitors disk memory, microprocessor load, number of processors, and currently running logs. It’s worth noting that you can also check other services including mail protocol, SMTP, HTTP and other network protocols.
How does Nagios work?
So, Nagios retrieves information about your server’s statistics via the NRPE agent, check_mk or via SNMP. An alert is then sent to you, and it tells you when the value of the metric is above a given threshold. After that, after each so called interval, it does a status check on the remote service by executing a plugin, and this sits on the remote client.
In fact, note these highlights of how Nagios works:
- Response.
- Monitoring.
- Alerting.
- Reporting.
- Maintenance.
- Planning.

Up next with Nagios vs Zabbix – What’s the Difference ? we guide you through Zabbix.
What is Zabbix?
Another tool in our list is Zabbix. Defined as open source for monitoring servers, networks or cloud services and virtual machines. Moreover, it provides metrics for monitoring and monitoring network usage, disk space consumption and CPU load. Interestingly, the tool has within it the ability to support various operating systems.
And these include Solaris, Mac OS and many others. A nice advantage of this tool is the use of a separate database for data storage and monitoring.
How does Zabbix work?
Active discovery: This mode allows Zabbix to actively send probes to specific devices or IP addresses to gather information about them. Also this is useful, if you want to gather more detailed information about a specific device, or if you want to scan a large range of IP addresses more quickly.
Network range discovery: Primarily, the mode allows Zabbix to scan a range of IP addresses and identify devices within that range. Moreover this is useful if you want to discover all the devices on a specific subnet or if you want to scan a large range of IP addresses to find specific devices.
Not to forget, Zabbix uses these three discovery modes to provide a comprehensive view of your network and its devices, allowing you to monitor its health and performance and identify potential problems.
Features of Zabbix
This network monitoring software provides various features to monitor and manage networks and devices. Some of the key features of Zabbix include:
Scalability
Designed to work on large networks with thousands of devices and is scalable to fit the needs of an organization. In addition, it also includes features such as Distributed Monitoring, which allows multiple locations to be monitored from a central location.
Security
Includes security features such as encryption and authentication to help protect your network and its data from unauthorized access. It also provides tools to identify and fix security vulnerabilities.
Monitoring
Basically, it monitors various network metrics including device availability, performance, and security. Alerts are sent when certain conditions are met, such as when a device goes offline or when a security breach is detected.
Integration
Integrates with many other tools and systems including databases, applications and cloud services. In turn, this allows you to collect and analyse data from multiple sources and view it in a single dashboard.
Network discovery
Uses a variety of methods including low level discovery, network wide discovery, and active discovery to identify devices on the network and collect related information.
Pros and cons of Zabbix
Pros
- Detects problems before the customer does and before it actually happens using the predictive functions in Zabbix.
- Extra features added, such as noise cancelling and facial recognition, which is great.
- Download it for free and modify it to fit your organization’s needs. Also, this significant benefits the organizations looking to customize their network monitoring solution.
- Creation of new alerts either fault based or performance based.
- Several options for monitoring, from agent to SNMP and so on.
Cons
- Zabbix is free to use, but can be expensive to install and maintain due to the resources and experience required. Some users may find that the cost outweighs the benefits.
- Installation and configuration are difficult, at times, especially for users new to monitoring systems. This requires a good understanding of network infrastructure and system architecture.
- Compared to other monitoring tools, it has a limited number of third party integrations.
- Doesn’t have an official support.
We have reached the main part of our article Nagios vs Zabbix – What’s the Difference ?
Nagios vs Zabbix - Key differences
Both, Nagios and Zabbix are open source network and infrastructure monitoring tools that help organizations monitor the availability and performance of their IT systems, devices and applications. Hence, both tools offer a wide range of features including alerts, reports and visualizations and are used to monitor a variety of devices and metrics.
Here are examples of how the two tools differ:
Cost and installation steps
In detail, Zabbix tool is much cheaper, easier to install on the user’s system and requires no additional installation steps. In contrast to Nagios, which is also has the free version but this has very limited functionality. The premium version is better. Nagios is expensive and requires additional assistance to install.
Visualization
In Zabbix tools, data are visualized in various forms such as screens, charts, overviews, and maps. This tool monitors your server, providing up to date statistics and performance information. But with Nagios data analysis and system monitoring are problematic because the tools lack data visualization capabilities.
Customization
Here, Nagios is known for its high level of customization that allows users to create their own plugins and scripts to monitor specific devices or metrics. Oppositely, Zabbix also offers a high degree of customization, but may not be as flexible as Nagios in this respect.
High availability and Automatically Fixing Issues
High availability with Nagios maintains system security and system high availability for other business operations. In essence, Nagios tools automatically troubleshoot whenever any situation arises. In contrast, Zabbix tools do not automatically fix problems. You will need technical support.
Database and Monitoring the system
Subsequently, with Zabbix tools, one centralized administrative web interface is used to manage data in the database and monitor the system. But Nagios, there does not have centralized system monitoring systems and data. All in all, Nagios tools use GUIs that use CGI to display web pages. Web pages contain graphics, buttons, and sounds that alert you to alerts. If more than one warning occurs, an immediate hard alarm is raised to notify the maintenance team.
Sending Alerts and Alarms upon any raised issue
In that case, Nagios tools send alerts immediately when unusual behaviour is observed on your system. You are able to take appropriate action on alerts. In the other hand Zabbix tools do not have the ability to send alerts and notify the technical team.
Monitoring Services
That is it. Thank you for reading Nagios vs Zabbix – What’s the Difference ? (Pros and Cons). Let’s conclude the article now.
Nagios vs Zabbix – What’s the Difference ? Conclusion
Finally, Zabbix is generally considered to be more scalable and feature-rich than Nagios, and it offers a more modern and intuitive user interface. However, let us remember Nagios is known for its high level of customization and a larger user base and community, which may make it a better choice for some organizations.
Ultimately, the choice between Nagios and Zabbix depends on the specific needs and resources of an organization. Both tools are widely used and have their own strengths and weaknesses, and it’s important to carefully consider the requirements of an organization when deciding which tool to use.
