Senior Enterprise Director at Towers IT
Utilize artificial intelligence for faster issue response and seamless ITSM integration
The data gathering capabilities and the automation, which utilizes artificial intelligence, are the most valuable features. These capabilities help us gather more information and analyze it faster, leading to better responses to issues. The tool is also excellent at integrating with ITSM services, providing a seamless alerting system for our customers.

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

"Customer service and support are superb."
"eG Enterprise has a single pane of glass for observability and monitoring."
"We haven't really had an issue per se, but there was a time when we had some network devices that were down, and eG showed us pretty quickly that that part of the network was down."
"Excellent level of support."
"User session details"
"It gives good insight into inside of what's going on with Exchange."
"The topology view which provides a visual representation of a service and quickly allows identification of errors or degraded performance."
"After trying many products with little satisfaction, we can finally say that we have found the best product on the market to monitor Citrix environments."
"The application performance monitoring feature is valuable."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"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."
"I like the way the solution sends alerts and how it keeps on escalating them."
"It sends alerts to the right people which ensures there is no delay in the correct person or team looking into issues, and it has helped to reduce downtime in the production environment to almost zero so we now spend less time on network or server administration."
"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"Open source and very flexible, with a large ecosystem of tools and custom monitors built up around Nagios."
 

Cons

"The solution needs to enhance the management dashboards."
"I would not buy this product again knowing what I know now. It takes too much time and it is still not where it used to be."
"Back-end configuration is not easy to implement."
"Application TCP latency is an area with room for improvement, but I believe this is already on the roadmap."
"Needs to improve the networking monitor capabilities."
"The interface could be improved as it is not real intuitive. It is not user-friendly."
"One thing that I don't like about eG is like the interface. It's not really that user-friendly to make a change, or to navigate through."
"The UI looks a little dated and could do with a refresh."
"Nagios' great customizability is also one of its greatest drawback."
"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."
"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."
"Would benefit from aggregations if a particular server goes down."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."
"The initial setup process could be easier."
"Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems."
 

Pricing and Cost Advice

"It is not expensive."
"The product is very cheap."
"The cost for eG Enterprise is almost $100,000 for one hundred and fifty services. It's subscription-based and the payment is yearly."
"We paid about 300,000 Saudi Riyal for the solution and it was quite affordable compared to the competition."
"They are aligned with other enterprise solutions."
"There are two licensing options: Perpetual and SaaS-based. The main offering, in terms of what eG prefers to offer, is the subscription-based rather than the Perpetual License. The price could be cheaper."
"They gave us a good price, when they were found out we were looking at other products because their price was very high. We were looking at another solution, then we came back to them was because they brought the price down. We selected them for three years."
"eG Enterprise is much cheaper than the other products it competes with."
"Nagios Core is an open source solution, and there are no licensing fees."
"It's free."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"The product is cheaply priced."
"It's free."
"I would rate the solution's pricing an eight out of ten."
"We are using the free version of Nagios Core."
"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."
