Enterprise Architect at ATOS
Monitoring traffic has improved cost control and threat visibility across network flows
The main area for improvement is AI-based features. Currently, many intelligent tools are coming from third parties, and Azure Network Watcher needs to improve in this area. The focus should be on getting better analytics and foundation models for proactive monitoring through AI models. While these capabilities exist, they are still in beta version. Azure Network Watcher should improve to match the capabilities that Google is targeting from an analytical point of view. Azure Network Watcher needs to improve foundation models in terms of AI-specific features and analytics, which are still evolving. This may take some time, but within one or two years, these improvements should reach a nine rating.

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

"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."
"The stability is very good. I rate it a ten out of ten."
"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."
"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."
"The solution is stable, there are no bugs or glitches and it doesn't crash or freeze, it's reliable."
"The solution is good for monitoring device behavior."
"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."
"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"For anyone who is interested in using this solution, I would recommend it."
"The product allows comprehensive monitoring of your environment, from basic monitoring of your servers health to more complex tasks like AD, database, and, to some extent, application-level monitoring."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails, and it also allows us to schedule downtime and maintenance."
"I can monitor a software made in-house to software of bigger companies."
"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"It's very easy to install it and manage it with Nagios XI's interface."
 

Cons

"Technical support from Microsoft needs significant improvement compared to other product vendors."
"The initial setup and initial learning curve could be improved to be easier."
"Azure Network Watcher needs to have better documentation and it needs to capture information accurately."
"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."
"Lacks sufficient security features."
"There are some occasional downtimes, but these were based on Azure-specific issues."
"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."
"The initial setup and deployment could be improved to be simplified."
"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."
"Initially, we encountered problems during the setup as some errors were noted due to a few prerequisites not being fulfilled and having some configuration files to edit and plugins to add."
"We'd like to see more integration capabilities."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"For some, it may be difficult to deploy."
"However, it is a bit complex and difficult for a first-time user."
 

Pricing and Cost Advice

"Price-wise, I have no information on how much Azure Network Watcher costs."
"Azure Network Watcher is a little bit expensive."
"The pricing is good. It's not too expensive."
"The price of the solution is reasonable."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios XI is open source."
"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."
"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 pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"Licensing costs are reasonable."
