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 product is simple to use."
"The ability to see what the end user response is, so I can get a better understanding of what the end user is seeing when they connect to the Citrix servers."
"Enormous capability to monitor Citrix environments."
"The most important feature is the ability to design, then implement monitoring tests on the fly as we are adapting to different situations."
"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."
"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."
"The GUI is nicer than all the other graphical interfaces out there."
"Its ability to monitor failures and to restart a Windows service when it fails."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"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."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"The application performance monitoring feature is valuable."
"I like the way the solution sends alerts and how it keeps on escalating them."
"The good thing about Nagios Core is it covers everything."
 

Cons

"Their dashboards could use some improvement. The ability to customize them a bit more."
"There should be more price flexibility to adapt to different kinds of customers. For small and medium businesses, eG Enterprise is usually too expensive."
"The solution needs to enhance the management dashboards."
"Back-end configuration is not easy to implement."
"In terms of areas for improvement in eG Enterprise, we are now moving most of our services to the OpenShift platform, and we need a way to monitor even containerized services or any service deployed on OpenShift, but that feature is still not available in eG Enterprise, so it's not good enough for us."
"Dashboards are difficult to create, and not so useful."
"Application TCP latency is an area with room for improvement, but I believe this is already on the roadmap."
"The interface could be improved as it is not real intuitive. It is not user-friendly."
"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."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"I would like to see more training videos."
"The tool needs to improve the integrations."
"There is room for improvement in the graphics."
"The user interface could be more interactive because it is pretty basic."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"The mapping is a little hard."
 

Pricing and Cost Advice

"The cost for eG Enterprise is almost $100,000 for one hundred and fifty services. It's subscription-based and the payment is yearly."
"eG Enterprise is much cheaper than the other products it competes with."
"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."
"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."
"If using eG for virtual desktops, carefully calculate whether per named user, per concurrent user, or per server"
"The product is very cheap."
"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."
"They are aligned with other enterprise solutions."
"Nagios Core is a cheap solution."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Nagios Core is free to use."
"We are using the free version."
"I would rate the solution's pricing an eight out of ten."
"We are using the free version of Nagios Core."
"The product is cheaply priced."
