We performed a comparison between Nagios Core and vRealize Network Insight based on real PeerSpot user reviews.
Find out in this report how the two IT Infrastructure Monitoring solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The single dashboard is a valuable feature."
"We can manage the entire system across the network and troubleshoot the pain points."
"The solution is quite efficient."
"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."
"Nagios Core is very configurable. Whatever you want, you can do it."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"The most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good."
"The application performance monitoring feature is valuable."
"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."
"Dashboard provides monitor of total assets."
"It provides deep visibility into what is happening with traffic and helps us manage our network."
"As a troubleshooting tool, it's a level-3 troubleshooting-skills tool and it's very easy to use and very easy to find the information that you need."
"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."
"It allows us to see how the network devices function as well as to see network glitches or fluctuations or dropping of packets."
"The initial setup was straightforward."
"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."
"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."
"With this product, we can precisely identify communication patterns between virtual machines within our data center, whether it's east-east or east-west communication."
"The technical support needs improvement."
"The Wi-Fi side needs improvement."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"The scalability needs improvement, it's not scalable at this time."
"There is room for improvement in the graphics."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"The core version is no match for the XI version."
"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."
"In a very general way, I would like to see an improvement in interoperability with third-party product, from other vendors."
"There are some random glitches in the Web UI, but they are usually pretty cosmetic in nature. I don't really seem to use any browser other than Chrome with it. I also get some weird errors from time to time on the hardware NetFlow Collectors, where it doesn't sync data."
"There could be some deeper analytics into packet inspection and trace flows. It could use some kind of machine learning to look at Layer 7 traffic for potential malware or corrupt packets."
"It needs to be a little easier to use and to understand the information it's putting out. That would make it more helpful. If you're not a network person you need to understand things like network policies and concepts. If you gave it to a regular admin, it would be nice if it were easier for them to pick up what is going on, understand the flows and whether or not stuff should be talking to each other, as opposed to just port groups and IP addresses."
"vRNI needs more remediation where it hooks into NSX."
"The solution can be improved by making it more compatible with other brands, allowing for better integration."
"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."
