Network monitoring provides comprehensive analytics while the interface requires further development
The quality of Azure Network Watcher is quite good in terms of the in-depth analysis you can create from these matrices. There are other monitoring tools such as New Relic, AppDynamics, and Dynatrace which provide very detailed network tracing. Cloud providers such as Azure or AWS do not have that kind of GUI-based capability at this point, but using PowerShell or Python, you can develop it yourself. From the GUI perspective, it still needs to evolve in terms of quality and standard, though overall, it is quite good for troubleshooting. Regarding areas for improvement, when comparing to other network tools beyond Azure Monitor or Azure Network Watcher, those tools can identify single failed packets. This level of granularity is not currently possible with cloud providers as they only go to a certain level rather than the granular level needed for deep troubleshooting, though they do provide hints with available matrices.

Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature of Azure Network Watcher is using the gateways with the connections. The monitoring is useful for the logs and application insights into the data. The traffic filtering issues when it comes to deploying those applications are helpful."
"The most valuable features I have found are typology, visualization, and capture."
"This is a stable system providing stable performance."
"The solution is stable."
"This will help the company or the administrator, by helping them see how the traffic moves, to make sure that no entities are having any communication issues or different endpoints with task issues."
"Azure Network Watcher provides valuable features based on your specific requirements and use cases, helping you monitor network bandwidth, throughput, data flow consumption, and control costs by giving insight into egress and ingress traffic, total input and output operations, bandwidth, and threats through IP identification."
"It provides good visibility."
"My advice to others looking into using Azure Network Watcher is to go for it, as you'll have the tool by default when you're subscribed to Azure VNet."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"In my experience with Nagios, I've found that the most valuable features are the scalability and extensibility through using scripts."
"Nagios XI allows my customer to monitor literally thousands of network and computing endpoints (both hardware and software) in real time, including custom derived SNMP polling and traps."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"Nagios XI is an outstanding network Monitoring tool, which can be tweaked to suit any environment and it is a good solution for business looking for remarkable features at zero cost."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements, it is flexible and easy to integrate with our systems, and you can customize the solution by adding additional features using code."
"Nagios is the best monitoring tool that I have ever worked on."
"This is a very good solution and it is simple to use, for any company."
 

Cons

"I still use Wireshark and Azure Network Watcher to get the required data. My team captures the traffic from Azure Network Watcher, downloads it, then imports that traffic into Wireshark to get more details on the number of hits and replies, for example. If you can do that on Azure Network Watcher and have Wireshark built-in, that would make Azure Network Watcher better. If Azure Network Watcher has that functionality where you won't need a third-party tool to get what you need, that would be helpful. I'm also expecting more from Azure Network Watcher. It's more complex than knowing how the IP flows from its source to the destination. The tool also needs more open-source features, such as having some built-in Wireshark that improves monitoring for customers. Sometimes, you encounter a VPN tunnel, network, or routing issue, but finding out more about the blockage is challenging. Is it one hundred percent an Azure issue? Is it a peer issue? You don't get complete information from Azure Network Watcher, so you must use other tools and depend on your strategies to resolve a specific issue. If more features could be added in the next release of Azure Network Watcher, specifically ones you can find on open-source tools, then that would be a plus point for the tool."
"Azure is good, however, the Fortinet GUI is more intuitive and I like it more than anything else."
"The solution could use some additional components of the network culture, not only VMs. I'd like to see some additional security features because what they currently have concentrates only on the network."
"User experience could be improved."
"There are some occasional downtimes, but these were based on Azure-specific issues."
"Lacks sufficient security features."
"The initial setup and deployment could be improved to be simplified."
"Azure Network Watcher needs to have better documentation and it needs to capture information accurately."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"Its simple deployment but complexity comes once you have to import more plugins."
"The installation can get very difficult depending on what Linux flavour you are using."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"Nagios XI isn't really good for scaling, in my experience."
 

Pricing and Cost Advice

"Azure Network Watcher is a little bit expensive."
"The price of the solution is reasonable."
"Price-wise, I have no information on how much Azure Network Watcher costs."

"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."

"The licensing fees for this solution are approximately $3,000 USD per year."
"The pricing is high with separate licensing for the product and support."
"Nagios XI is an expensive solution."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."

"As it is not an agentless tool, I think it is expensive."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
