Why I picked Cacti

Cacti is a free tool with the capabilities to provide the basic functions of network monitoring, provided that your team has staff that can understand statistical modeling and can connect and maintain the SNMP hook-up.

Why I picked Nagios XI

Nagios XI comes in two editions that build upon the Nagios Core edition. Growing companies that plan to expand their networks can easily scale from the free and open-source Core edition to the enterprise edition. I think this is especially helpful for organizations that need multi-tenant capabilities.

Standout features

You’ll get plenty of templates applied by default. Some of these include templates for HTTP, ICMP, SMTP, and IPMI protocols, as well as templates for Linux and Windows Server systems.

Other notable features of Zabbix include:

• Flexible metric collection.
• High-performance Zabbix agents.
• Agentless monitoring.
• Synthetic monitoring.
• Custom data collection methods.

It’s flexible.	The user interface isn’t the best.
It can send you alerts when a device or link is down.

Use cases

Zabbix is a good fit for larger businesses, especially if they have more complex needs. Keep in mind, though, that Zabbix needs to be configured manually, component by component. Since the interface isn’t too intuitive, you may have to ask the support community for assistance.

It has all the features SMBs need for network monitoring.	It may not have the capacity to manage larger and more complex enterprise environments.

Use cases

I recommend Paessler to people with small-to-medium-sized businesses and network environments.

Why I chose Paessler PRTG Network Monitor

I chose Paessler PRTG Network Monitor because the five different pricing plans provide excellent scalability. I also like that it provides full reporting modules, making a fully featured solution for Windows-only SMBs. However, the price is higher than some open-source options on this list, and it only supports WIndows, so it’s not suitable if you also use MacOS.

It allows you to analyze packets on many different interfaces.	You may get overwhelmed with the network information the platform throws at you at first.
It’s easy to identify and troubleshoot latency issues.

Use cases

Wireshark seems to perform well for many business sizes and use cases. However, small businesses may have a few problems navigating the platform. It sometimes overwhelms smaller teams with the amount of information it provides.

Why I chose Wireshark

I chose Wireshark because it’s a highly popular open-source software with a large community that offers many support resources, including education, a conference, and documentation. I also appreciate that it’s available for many protocols and operating systems, which is ideal for high-growth companies that will need to extend their monitoring.

What are the key features of network monitoring software?

There are dozens of different monitoring tools you can find online, but how can you make sure you’ve found the right one for your business? As a starting point, look for solutions that include these key features and capabilities:

• Real-time monitoring.
• Traffic analysis.
• Fault detection and alerting.
• Performance analysis and bandwidth usage.
• Customizable dashboards and reports.
• Remote monitoring capabilities.

Some products may have all of these features, whereas others may just have a few. It will be important for your team to determine which features are non-negotiable.

Factors to consider when choosing your next network monitoring tool

Not all tools are a one-size-fits-all solution. You must consider your needs and goals as a company if you truly want to choose the perfect network monitoring product and hopefully save money in the process.

Take your time when thinking about the particularities of your networking environment and the type of attention it requires. From there, you can select a product that’s a good fit for your business size, team expertise, security and compliance requirements, and much more.

Here are some factors you should keep in mind when choosing network monitoring tools:

• Your organization’s scalability requirements and the current size of your network.
• Your team’s in-house technical expertise and ease-of-use requirements.
• Integration with other IT management tools.
• Cost and licensing options.
• Vendor reputation and support.

Open-source vs. commercial network monitoring solutions

Open-source software is free, which is probably its best feature. Users don’t have to closely partner with or meet vendors to access, configure, and customize these tools to their liking. Open-source platforms also often receive support from their communities, meaning you’ll get regular updates and access to a forum where you can share your concerns with other people.

Unfortunately, since open-source platforms are less regulated, you may experience more problems or bugs while using this type of tool. Moreover, you will be responsible for fixing these problems most of the time.

Open-source updates are provided by volunteers, so there’s no set schedule for receiving them. This may be a setback for those who are looking for updated tools.

In contrast, commercial solutions offer users stability and maturity with standardized products. However, these products usually come with a higher price tag and may have greater limitations placed on user-level customizations.

Which one is right for your organization?

Does your team have people willing to deal with the volatility of open-source software? If it does, then you can save some money and select an open-source network monitoring solution.

On the other hand, if you have the budget and don’t want to worry too much about quality or stability, commercial network management tools will be a better fit. Regardless of which one you use, if you use your tool alongside IT network monitoring best practices, you’ll achieve consistent results that improve your network as a whole.

Protecting your network with network monitoring tools

Today’s digital world is filled with many potential risks. You must be prepared to monitor your network performance and activity at all times, whether it’s your wireless networks, firewalls, or another component that lives on your network.

The network monitoring solutions covered in this guide do an excellent job of keeping everything safe. However, we recommend you take your time to consider your organization’s specific needs and goals. Each tool has different features that’ll help you, but a thorough evaluation will help you choose the right option.

Research methodology

In my search for the best network monitoring tools, I consulted product documentation and user reviews. I considered features such as different types of monitoring, device templates, graph templates and viewing options, data source management, and plug-ins. I also weighed other factors, such as pricing, user interface design, customer support resources, automations, and reporting.

FAQ

What are network performance monitoring tools?

Network performance monitoring tools collect data for network devices, then display it all in consolidated visualizations. Some of the data gathered by network performance monitoring tools include devices, network flow data, and packet data. Network monitoring tools don’t just report on the health of the network; they can also be used for troubleshooting and optimizing to improve performance.

What is the most widely used network monitoring and management protocol?

Simple Network Management Protocol is the most widely used network monitoring and management tool. SNMP is an application layer protocol that collects data on network devices and their status changes. Other common network monitoring protocols include the Internet Control Message Protocol, the Cisco Discovery Protocol, and the Link Layer Discovery Protocol.

What is the difference between network management and network monitoring?

Network management is a broad category that encompasses many different kinds of tools that NetOps teams use to create and maintain a strong, healthy network. Network monitoring is a specific type of network management that involves collecting data from network devices and then creating visual representations of that data. This network monitoring data is usually consolidated into a single dashboard so the NetOps teams can get an overview of the network status and performance in one place.
