Has the capability to automatically integrate with a large number of products
Scalability-wise, I rate the solution an eight out of ten. I have not worked much on other technologies, like SAP or VMware's virtualization part, on-prem infrastructure, or cloud infrastructure. Instana Infrastructure Monitoring is so fast and easy to adapt that it works fine. I have not explored other operating systems or infrastructure solutions because my company doesn't have that customer scale. Most of our customers are on-prem or on AWS or Azure, but Instana Infrastructure Monitoring adapts to their infrastructure very well. My company came to know how well Instana Infrastructure Monitoring adapts to our customers' infrastructures when we take care of the PoC phase. Around 12 to 15 people in my company use the product.

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

"The product's initial setup is easy."
"The product is easy to deploy."
"Dashboard provides monitor of total assets."
"The reporting structure and the feature set are valuable to me."
"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."
"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."
"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."
"This product covers all of our infrastructure health checks, and has triggers for us to alert us to any unusual behaviour of the monitored systems."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
 

Cons

"Instana Infrastructure Monitoring needs to support monitoring of the .NET framework since it is one of the areas where the solution currently has shortcomings."
"The product’s scalability is an area with certain limitations, making it an area where improvements are required."
"Nagios Core does not have a graphic display."
"Some of the reporting functionality is a bit basic and configuration is a chore although by the use of NagiosQL this can be made a lot easier."
"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."
"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."
"I like to have the option to configure Nagios using the web interface."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"The dashboard and monitoring features could be improved."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
 

Pricing and Cost Advice

"The cost of the tool is around 130 USD per month."
"I would rate the solution's pricing an eight out of ten."
"We are using the free version."
"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."
"We are using the free version of Nagios Core."
"The product is cheaply priced."
"It's free."
"Nagios Core is an open source solution, and there are no licensing fees."
"The solution is expensive."

What is your experience regarding pricing and costs for Nagios Core?
Nagios Core is a free and open-source product. We don't charge for the product itself, but we charge for the man-hour costs related to installation, configuration, ongoing operation, and maintenance.
What needs improvement with Nagios Core?

What is your primary use case for Nagios Core?
