A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility

We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

The tool's configuration is easy and artifacts are easily accessible through professional services and the web

The product is highly regarded, and many customers have been using it along with other VMware products like vSphere and VMware vCloud Usage Insight. However, recently, there's been a trend among customers, especially those using VMware for a considerable period, to explore the potential of migrating to the public cloud. The common concern among these customers is how the VMware products will perform in the public cloud environment. Migrating instances from VMware to different platforms is not easy, especially when dealing with many instances across multiple customers. Customers are keen to maintain the functionality of their existing VMware products but prefer to run them on the public cloud instead of on-premise servers. Our clients for vRealize Network Insight are enterprise businesses. I rate it a nine out of ten.

Quotes from Members

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

Pros

"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."

"Being open source lets us customize it for our monitoring needs, saving us money."

"It's very easy to manage and monitor it."

"It is easier for client installation, and the configurations are doable even for a newcomer in the field."

"The most valuable feature is the profiling of the applications for micro-segmentation... It has made the migration to NSX much easier. Most of the sys admins within the smaller silos, they have no idea what ports are needed to run their stuff at all. I am pretty sure the micro-segmentation would never, ever have occurred without it."

"A lot of time is saved when you use this type of software solution for the network. We have moved systems into the new data center and the servers and systems are much faster because of the very low latency between virtual machines."

"Whenever we say "valuable" with respect to the network, it's more towards the security. The firewall rule issues it shows us and the recommendations that we get from vRNI are the most valuable features because they are actually making our network more secure."

"It is user-friendly. It's pretty simple to deploy and to run. It gives you pretty easy-to-understand reports, very graphically intense, so you can visualize what's going on in your network."

"The initial setup was straightforward."

"The most valuable feature for me is the different views that you can get when selecting an application or a VLAN. It shows you the traffic flows. It gives you a visual representation of something that, in text, just may not make as much sense."

"The gradual way the Network Insight shows you all the relevant information about your networks. It's pretty good. You can really dig deep deep inside and see where the problem is, where it comes from, what you have inside, how did you configure it. Also, it has alerts so you can have pretty much quite a big overview about your network. This is really something good."

"compare-to-competition; I would recommend the product. I don't think there is any other product like this on the market right now."

Cons

"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."

"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."

"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."

"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."

"If it were more application-aware, more descriptive; if it were able to determine the application that is actually doing the communication, that would be easier. More application information: which user or account it's accessing, is it accessing this application, doing these calls, if it is accessing a script, what script is it accessing. Things like that would provide deeper analytics so I can track what's going on. It would not just be, "These people shouldn't be talking," but who is actually doing these calls."

"I would like to see them expand the capabilities to infrastructure types other than just VMware."

"The solution is very much viewer centric and it would be nice if it would transcend just the virtual infrastructure."

"In a very general way, I would like to see an improvement in interoperability with third-party product, from other vendors."

"There's enough information there, especially in the visualizations, but I would love to see this in a kiosk mode, where I could have a dashboard for interested stakeholders to see and appreciate what's going on. Then, moving on to a more practical level for our Help Desk, our operations team could benefit by seeing, in real-time, a visual view of the network."

"The only reason I would not give it a nine or a 10 is for cost reasons. It seems to be one of those things that really belongs as part of the product inherently and not as an add-on. That would be my only concern."

"The only issue we have is that the solution does not always capture the host names."

"The virtual appliance has rebooted."

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."

"It reduces costs. It takes something that may be challenging and makes it more usable and visual by being able to bring in tools, seeing what their impact is, such as microsegmentation and application rationalization, and seeing it quickly."

"The solution has helped us to reduce time, increase performance, reduce costs, and even easily manage networks. We are probably seeing 10 to 20 percent labor savings because we are able to be very specific and focused on what we want to do. It ends up saving the customer money and makes us be more efficient on our cost deliveries."

"It's an expensive product because we have a lot of nodes."

"Cost always has room for improvement, you could always make it cheaper. But I think it's a good value for what you pay for it."

"It's a little expensive, but for what you're getting out of the product, you often see the trade-off. It depends on the type of licensing you have. It might be a little too pricey for some."

"I rate vRealize Network Insight's pricing a seven point five out of ten."

"We have spent less time investigating network flows, so it is absolutely cost-effective."

"It has brought more money into our company."
