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 solution is stable."
"We use the solution to monitor network services. It helps to capture any network issues."
"This is a stable system providing stable performance."
"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 solution is good for monitoring device behavior."
"The most valuable feature of Azure Network Watcher is the cloud-native application firewall, which is helpful for securing databases."
"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."
"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."
"Nagios Core is very configurable. Whatever you want, you can do it."
"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."
"I would rate the overall solution ten points out of ten."
"I like the way the solution sends alerts and how it keeps on escalating them."
"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."
"The solution is very complete and mostly easy to manage."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"It sends alerts to the right people which ensures there is no delay in the correct person or team looking into issues, and it has helped to reduce downtime in the production environment to almost zero so we now spend less time on network or server administration."
 

Cons

"Azure Network Watcher could improve by having other built-in applications, for example, an application to log activities for inbound and outbound traffic."
"Azure Network Watcher needs to have better documentation and it needs to capture information accurately."
"Lacks sufficient security features."
"There are some occasional downtimes, but these were based on Azure-specific issues."
"Azure is good, however, the Fortinet GUI is more intuitive and I like it more than anything else."
"Azure Network Watcher could improve by having other built-in applications. For example, an application to log activities for in and outbound traffic."
"The initial setup and deployment could be improved to be simplified."
"The initial setup and initial learning curve could be improved to be easier."
"Some of the reporting functionality is a bit basic and configuration is a chore although by the use of NagiosQL this can be made a lot easier."
"I would like to see more training videos."
"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."
"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."
"The core version is no match for the XI version."
"t was a little hard to get our setup represented in the configuration."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"Nagios Core would benefit from aggregations if a particular server goes down."

"The solution is expensive."
"I would rate the solution's pricing an eight out of ten."
