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.

Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

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."
"What I like most about Azure Network Watcher is that it's focused more on the architecture. I also like that it has a packet capture feature that tells you how the packet travels and whether it's exiting Azure, etc."
"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."
"The stability is very good. I rate it a ten out of ten."
"I like the visibility."
"The solution is good for monitoring device behavior."
"This is a stable system providing stable performance."
"The solution is stable, there are no bugs or glitches and it doesn't crash or freeze, it's reliable."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"Nagios Core is stable."
"Nagios Core is a great solution for monitoring pretty much any size of deployment but you do need to know your way around a Linux system to set it up and run it."
"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."
"The solution is very complete and mostly easy to manage."
"Dashboard provides monitor of total assets."
"Provides timely notifications."
 

Cons

"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."
"Azure Network Watcher needs to have better documentation and it needs to capture information accurately."
"Lacks sufficient security features."
"It's not the most friendly or straightforward to set up. I don't see the value versus the way you have to set it up at first."
"Azure Network Watcher could improve by having other built-in applications, for example, an application to log activities for inbound and outbound traffic."
"Sometimes, you encounter a VPN tunnel, network, or routing issue, but finding out more about the blockage is challenging."
"The solution could improve by limiting the need to clarify the logs. When the clarification is minimized, it is better for everyone involved."
"There are some occasional downtimes, but these were based on Azure-specific issues."
"The initial setup process could be easier."
"Nagios' great customizability is also one of its greatest drawback."
"t was a little hard to get our setup represented in the configuration."
"Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems."
"I like to have the option to configure Nagios using the web interface."
"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."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"Generally, it does what I need it to do, but better error reporting would be great."
 

Pricing and Cost Advice

"The pricing is good. It's not too expensive."
"Price-wise, I have no information on how much Azure Network Watcher costs."
"Azure Network Watcher is a little bit expensive."
"The price of the solution is reasonable."
"The enterprise version has technical support. The version we are using is free."
"I would rate the solution's pricing an eight out of ten."
"We are using the free version of Nagios Core."
"It's free."
"We are using the open-source, unpaid version."
"It's free."
"Lessening the price point would be an improvement."
"Nagios Core is a cheap solution."
