Great for identifying application interdependencies with helpful support but needs better visualizations
We're just trying to identify the application interdependencies, which normally reside on different servers, including web servers, database servers, enterprise service bus, et cetera, up to your presentation layer before we start moving stuff around. Normally, the reason why we use these tools is to understand what assets we have, where they're deployed, and how they enter and operate before we decide to go move something from point A to point B. The solution is going to allow me to establish a wave or migration plan where you have different waves of migration and then you actually have move groups to try and get your application moved from A to B seamlessly. A to B could be on-premise to on-premise. It could be on-premise to cloud. Et cetera. The solution can tell me what components can I deploy, for example, into a cloud space, without having to refactor my applications since that can be quite time-consuming and costly.

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

"ExtraHop came out with the best price, and I think that it gives us a broader view of our network."
"The most valuable features are security detections, perimeter detection, dashboards, and alerts."
"ExtraHop is far ahead of anything comparable in the industry."
"Wire data analytics."
"This is a must-try product."
"This solution is more applications reference architecture focused. Its benefit is that it specializes in that space."
"It gives you full 360-degree visibility into your entire infrastructure."
"Not only can you look at the protocol import level. It also has a live PCAP analysis."
"We are using Nagios Core on a VM and it's working very well, even though the specs of the VM are very low because it doesn't require much storage."
"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."
"This is a fit for purpose product which means that if you have a definite list of requirements and are not willing, or unable, to spend money on big enterprise tools, then Nagios is a tool to go to."
"Extensibility is good as this makes it easy to write checks on your own."
"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."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"Nagios allows IT staff and end-users to see the status of critical services on the network and can alert and notify selected users if critical services fail, reducing the mean time to recover."
"We have used this product now for quite some time and we are happy with it."
 

Cons

"They either have to go broad or decide what their bread and butter is and get really good at that."
"There is room for improvement in the security part. They have a new solution, ExtraHop Reveal(x), and I think it needs improvement."
"We've had some struggles getting it to see everything that we want to see. Network visibility is something that needs to be improved."
"The improvement that would make the most impact would be expanding on the new EXA big data back end."
"The solution could get more aggressive in the discounting of the overall cost."
"We'd like to see a local presence within the region in order to have seamless service whether it's the support, the implementation, or professional services."
"Additional out-of-the-box solutions and use cases would be nice."
"This solution would be improved if it had the ability to retain data longer."
"The mapping is a little hard."
"Nagios Core is not easy to use, so I don't recommend it for everyone."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"The configuration and reporting modules need to be improved."
"I like to have the option to configure Nagios using the web interface."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"The scalability needs improvement, it's not scalable at this time."
 

Pricing and Cost Advice

"The pricing is fair considering the value provided."
"The price of this solution for our environment is about £650,000 ($855,000 USD) for three years."
"The pricing is higher than other solutions, but with such good features, I think it's worth it."
"Lessening the price point would be an improvement."
"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."
"Nagios Core is free to use."
"It's free."
"The enterprise version has technical support. The version we are using is free."
"The product is cheaply priced."
"Most the plugin features are free."
"Nagios Core is an open source solution, and there are no licensing fees."
