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

"The auto-configuration or auto-Thresholding is very important because it saves a phenomenal amount of labor and setup costs and time."
"Some of the best features of eG are, in terms of APM, they have complete modules between application performance monitoring, server monitoring, and even storage and network-based monitoring. The UI is also quite good. They have some standard AI-based capabilities, even though it's not quite as advanced when compared to Dynatrace. eG has some good, basic APM capabilities."
"Enormous capability to monitor Citrix environments."
"Its ability to monitor failures and to restart a Windows service when it fails."
"The data gathering capabilities and the automation, which utilizes artificial intelligence, are the most valuable features."
"The topology view which provides a visual representation of a service and quickly allows identification of errors or degraded performance."
"The GUI is nicer than all the other graphical interfaces out there."
"Sometimes when we face issues with the new technologies or very old technologies where we cannot enhance the service, they move to work with us directly and start doing some development on this area which is very good for us."
"I like the way the solution sends alerts and how it keeps on escalating them."
"Nagios Core is very configurable. Whatever you want, you can do it."
"The application performance monitoring feature is valuable."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"The reporting structure and the feature set are valuable to me."
"Nagios Core is stable."
"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."
"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."
 

Cons

"Dashboards are difficult to create, and not so useful."
"eG Enterprise's licensing could be cheaper. Even compared to Dynatrace, I think the price is quite expensive considering the APM functionalities, even though they have other benefits such as info monitoring."
"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."
"There should be more price flexibility to adapt to different kinds of customers. For small and medium businesses, eG Enterprise is usually too expensive."
"would like to see improvements in the alarm display console."
"Needs to improve the networking monitor capabilities."
"The integration must be improved."
"Would benefit from aggregations if a particular server goes down."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"The user interface could be more interactive because it is pretty basic."
"Nagios Core does not have a graphic display."
"I would like to see more training videos."
"The dashboard should be improved."
"The UI is a little outdated and graphics could be displayed in a better way."
"The interface could be improved."
 

Pricing and Cost Advice

"The product is very cheap."
"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."
"If using eG for virtual desktops, carefully calculate whether per named user, per concurrent user, or per server"
"You may get some monitoring products with certain licensing you may own. Some of these can take ages to configure and setup, along with needing a license to drive the software."
"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."
"The cost for eG Enterprise is almost $100,000 for one hundred and fifty services. It's subscription-based and the payment is yearly."
"They are aligned with other enterprise solutions."
"It'd be nice if the price was lower. That would be an improvement."
"We are using the free version of Nagios Core."
"We are using the free version."
"I would rate the solution's pricing an eight out of ten."
"Nagios Core is a cheap solution."
"Lessening the price point would be an improvement."
"The enterprise version has technical support. The version we are using is free."
"We are using the open-source, unpaid version."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
