Assistant Manager at Lauren Information Technologies Pvt Ltd
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."
"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."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"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."
"Nagios Core is a great solution for monitoring pretty much any size of deployment but you do need to know your way around a Linux system to set it up and run it."
"The reporting structure and the feature set are valuable to me."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"I would rate the overall solution ten points out of ten."
"We use the product to monitor server applications."
 

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."
"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."
"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."
"Nagios' great customizability is also one of its greatest drawback."
"Nagios Core would benefit from aggregations if a particular server goes down."
"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."
"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"This is the open source product, so it's a toolkit rather than a complete solution."
 

Pricing and Cost Advice

"The cost of the tool is around 130 USD per month."
"We are using the free version."
"It's free."
"I would rate the solution's pricing an eight out of ten."
"It's free."
"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."
"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?
The dashboard should be improved. It's very simple. I don't have a very clear or specific suggestion. You can change the skin of the dashboard, however, it's good for me.
What is your primary use case for Nagios Core?
I was a senior system administrator. I've been using Nagios Core for more than ten years now. It can be used to monitor hosts, such as machines, and monitor services of any kind. I'm using it to mo...
