On sprawling enterprise networks, it becomes increasingly difficult for network administrators and developers to identify and correct every issue that arises. In reality, even if these professionals had the time to correct all network problems, their energy and expertise could be better spent on more strategic and complex initiatives for the network.
Network troubleshooting and diagnostic tools work to support these professionals with automated detection and basic problem-solving for network performance. Read on to better understand what network troubleshooting and network diagnostic tools do and what some top vendors offer their customers.
Network troubleshooting tools are tools that, in addition to offering other basic network monitoring features, identify and correct problems across the network and its various endpoints. Network troubleshooting tools look for network disruptions and anomalies and work to follow service level agreements (SLAs) so that the network runs quickly, efficiently, securely, and compliantly.

Some network troubleshooting and diagnostic tools are open source, command-line tools that are flexible enough to work on a variety of platforms, but many of these tools don’t offer the same in-depth insights and automations on their own until they’re integrated with a bigger platform. More holistic network troubleshooting and diagnostic tools, on the other hand, will offer a variety of analytics and support features, and they will also improve the user experience with network traffic and behavior maps that help to identify network bottlenecks visually.
Regardless of the type of tool or collection of tools that you think you want, consider these common network diagnostic tool features, and more importantly, make sure you know which ones are most important to your business and if they’re available in your preferred tools:

Auvik is one of the simpler tools on this list with a strong focus on logging and root cause analysis. It is a cloud-based network diagnostics solution that is highly praised for its speed and accuracy, as well as its easy-to-understand data visualizations. Visualizations in particular are a top feature for Auvik, as customers have the ability to manipulate their network maps and models to exactly what they need; it is a strong option for teams that have less experience building out and interpreting network data on an enterprise scale.
Pro: Auvik offers strong and holistic network visibility, particularly through its robust network mapping features.
Con: Some users have commented on the limitations of Auvik’s reporting features.
Pricing: Auvik offers Essentials and Performance pricing packages to its customers. Learn more about pricing here.
ManageEngine OpManager offers a variety of other solutions and use cases beyond network diagnostics, but its support for diagnostics and troubleshooting is a strong feature for finding network problems in switches, routers, servers, and storage devices. Particularly at the server level, OpManager is helpful because it allows administrators to set performance thresholds from initial deployment, which makes notifications about potential network problems more accurate and timely.
The user interface for OpManager is also friendlier than most tools in the diagnostics market. With simple and customizable data visualizations and a clear administrative dashboard, this tool works for a full spectrum of network management experience levels.
Pro: OpManager not only focuses on network diagnostics but also offers several tools and features for follow-up network optimization needs.
Con: OpManager has frequent point releases to update its features, but these new features often come with bugs that aren’t resolved immediately.
Pricing: Pricing information is available upon request from the ManageEngine sales team.
NetSpot is a diagnostics and troubleshooting solution that focuses on creating wireless site surveys, primarily for local area networks (LANs). Although this is a great tool for understanding how an existing network is functioning and where problems lie, this is actually a top solution for creating an optimized plan before launching a new network. The Wi-Fi site survey that NetSpot offers can help networking professionals determine where cables, antennas, and other important networking equipment should go for the best service. These site surveys and the data visualizations they produce will continue to be useful as the network grows and new service bottlenecks need to be corrected.
Pro: NetSpot supports a variety of Wi-Fi security goals, including rogue access point identification, unauthorized workstation and user detection, and elimination of false-positive alerts.
Con: The free version of this solution offers only limited data on network metrics like dead zones.
Pricing: NetSpot comes in four different pricing package options: NetSpot FREE Edition, Home, PRO, and Enterprise. Learn more about pricing here.
Wireshark is an open source network diagnostic and management solution. Consistent network traffic capture and filtering capabilities make it easier for networking teams to not only identify problems but to quickly determine which problems are most urgent. The open source format of Wireshark means that it receives frequent updates, which can be a pro or a con depending on the user. The pro is that new features are constantly added and documented for the tool, while the con is that the tool’s performance can get bogged down in new features with occasional bugs. Teams that keep up with updates and changing documentation will experience the most success with this tool.
Pro: The open source format of Wireshark leads to very clear documentation and frequent user-driven updates for the tool.
Con: Wireshark’s functions are very reliant on the OS you choose to use it with; if your operating system is outdated or limited, Wireshark will not work very well.
Pricing: Wireshark is free, open source (FOSS) software under the GNU General Public License version 2.
The previously mentioned network diagnostic tools offer a variety of troubleshooting strategies and features to customers, but often with a greater learning curve and additional administrative expense.

Network troubleshooting and diagnostic tools support network administrators in a variety of network management areas, including more efficient operations, increased analytical insights, and heightened visibility for security and compliance issues. These are some of the main benefits that enterprises discover when they invest in a diagnostic toolset for their network:
In most traditional networks, problem-solving and troubleshooting begin once a major error is discovered by a networking or security professional. With troubleshooting and diagnostic solutions, network errors are discovered at an earlier stage and automatically alert these professionals to the rising issue. The earlier identification of network issues gives the team precursive knowledge to resolve any connectivity, latency, or security issues before they bring parts of the network down.
Especially on larger enterprise networks, the exponential number of endpoints can make it difficult to determine where anomalous traffic is entering the network. Diagnostic and troubleshooting tools are used to find and alert network administrators to the what and where of unusual network behaviors and unauthorized users, thus increasing endpoint-, device-, and user-level insights for security needs.
Administrative network visibility provides other benefits beyond security. Seeing how users and devices interact with the network helps network professionals to identify bottlenecks and inefficiencies that negatively impact the user experience. Some diagnostic tools even offer the data visualizations and reports necessary to understand which parts of the network need to grow to meet new business needs and which parts can be scaled back.
Almost immediately after their deployment, network diagnostic tools help networking teams find new ways to save time in network management. Troubleshooting and diagnostic tools are designed to target individual network components, which streamlines network management data and makes it easier for professionals to visualize and correct problems in a focused area.
With their automated workflows, machine-learning powered resolutions, and detailed reports and visualizations, diagnostic tools also take over the most tedious parts of network troubleshooting for the networking professionals who used to perform this work manually. With their time freed up from previous troubleshooting tasks, network and security professionals now can focus on higher-value needs for the network and business.
