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 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."
"I like the way the solution sends alerts and how it keeps on escalating them."
"We use the product to monitor server applications."
"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. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."
"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 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."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"It gives the visibility that was either broken or there in pieces only. This solution provides a unified view of the whole system, back and forth. It has helped to reduce time to value, increase performance, more easily manage networks, and provide deep visibility."
"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."
"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 allows us to see how the network devices function as well as to see network glitches or fluctuations or dropping of packets."
"The most valuable feature is the visualization. It's really handy to be able to classify network objects as with applications and see the interaction between them."
"It especially helps with deploying NSX, that you're not having to manually chase down and figure out what you need to do to microsegment VMs. This gives a nice option where you can say, "Hey, this VM, show me what flows are there." I can export it out and then import it as an NSX rule and job done."
"It allows us to go from virtual through NSX, up to the core, and see all of that in one pane of glass, it's pretty easy."
"The graphical interface of this environment is so good with all the views, the graphics, and everything in them. It's really easy for me. It doesn't need an engineer to work on it. It's easy enough that anyone can get into the environment and look for issues or look at how communication is going on across the VMs. It's pretty much straightforward."
"The Wi-Fi side needs improvement."
"The UI is a little outdated and graphics could be displayed in a better way."
"The dashboard and monitoring features could be improved."
"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."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"There is room for improvement in the graphics."
"The scalability needs improvement, it's not scalable at this time."
"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."
"The initial setup process could be easier."
"The solution can be improved by making it more compatible with other brands, allowing for better integration."
"If it had some kind of plugins with vSphere, more effective plugins with Horizon View or other VMWare products, if it had interconnectivity, I think it would be more effective than it is today."
"It just needs to be more reliable and more accurate. At some point, there are some things where it does not match properly."
"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."
"I'd like to see better support for being able to search the hardware NetFlow data. It ingests fairly well, but you can't tell, in a lot of cases, what source the data came from. I'd like to see more support for picking specific sources. That way you could really make a compelling use case. There are also some difficulties where it can't exactly trace the path between source and destination but if you hit the reverse flow on the same search it shows the entire path."
"There is room for improvement when it comes to pricing because we pay here in Brazil, and all the costs are based on the dollar."
"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."
"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."
