We performed a comparison between Nagios XI and vRealize Network Insight based on real PeerSpot user reviews.
Find out in this report how the two Network Monitoring Software solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."We can manage the entire system across the network and troubleshoot the pain points."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"Nagios XI helped me to draw the network and check for system failures."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"I can monitor a phone on a desk to very big servers of any company."
"The dashboard allows you to see what's going on in the overall system."
"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. You can customize the solution by adding additional features using code."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"The best feature of this application is its ability to capture everything within the same application, as well as capture all the traffic."
"The most valuable feature for us is that insight into what our network is really doing - it's a fairly complex network. Not having to go through thousands of lines of network configuration to find firewall ports that were open or closed, for various ports, was very valuable. It went out and found everything we need very quickly."
"vRNI can trace the flow of each and every packet and it is easy for us to troubleshoot all the issues that we do have with the networking. We can trace down the packet to a point where it has been dropped."
"I like being able to see the flows coming in and out of the product. In terms of monitoring network flows, we use it to verify whether or not different servers/applications should be communicating with each other."
"It allowed us to set up NSX and to do microsegmentation, without all of the pain points of having to determine each port and each IP address that needed to have access, and which ones needed to be blocked."
"It allows you to see traffic that you couldn't otherwise see, which is traffic within your Layer 3-bounded network, meaning east-west traffic. It's hard to get that any other way."
"The tool's ease of configuration and use and the availability of information and artifacts through professional services and the web are key factors that customers find valuable."
"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."
"The Wi-Fi side needs improvement."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"The interface could be more user-friendly."
"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."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"Nagios XI can improve its GUI for users with a new look."
"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."
"The reporting structure could be more streamlined."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"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."
"I would like to see application identification. That would be cool."
"When we talk about those micro-segmentation rules, there's an Export function. It is very macro-segmentation oriented instead. So if you choose an application, it will find the tiers within that application and say that it's communicating on, say, port 80 to a separate VLAN. There might be 200 machines in that other VLAN. You don't want to open port 80 at all of them. So we need a lot more granularity in those suggested firewall rules."
"In a very general way, I would like to see an improvement in interoperability with third-party product, from other vendors."
"I want to see more in terms of microsegmentation. As of now, I can see the rules, but they are not in a readable format that I can convert to microsegmentation and can fit into NSX Manager."
"I would like to see them expand the capabilities to infrastructure types other than just VMware."
"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."
"While it's not exactly a feature, what normally happens when we are trying to look at the VM flow portion is - although Network Insight does have options to integrate a few physical switches into it - we can't really get an end-to-end flow of the network. We might be using a few switches that are not supported by Network Insight. That is where they can improve, in the support for more physical switches and network devices."
