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

"It gives you full 360-degree visibility into your entire infrastructure."
"ExtraHop came out with the best price, and I think that it gives us a broader view of our network."
"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."
"Open source and very flexible, with a large ecosystem of tools and custom monitors built up around Nagios."
"The reporting structure and the feature set are valuable to me."
"We mostly use Nagios Core to integrate with Python and Bash Script."

Cons

"We've had some struggles getting it to see everything that we want to see. Network visibility is something that needs to be improved."
"I would improve the Rule-Based Access Control (RBAC) by providing granular access control to the data."

"Nagios Core is not easy to use, so I don't recommend it for everyone."
