Efficient monitoring with detailed customization, yet complexity remains

The best feature of WhatsUp Gold is the automatic generation of topology and its integration with virtualization and wireless. I have used the automated device discovery with this topology feature. The interactive map feature helps me manage the topology because sometimes we cannot draw the topology correctly, so we need to manually edit the connections. The alerting system is very tunable and customizable, but it's a little complicated to use. Many customers cannot manage it by themselves and need support from us, the provider. We always use the dashboards in the SOC, where we constantly display a dashboard or multiple dashboards. This allows us to know immediately if the connection or bandwidth is full or if the connection is broken.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"You should really try Nagios; it will help a lot and I have found that it is the best buddy for system admins."

"The application performance monitoring feature is valuable."

"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."

"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."

"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."

"Open source and very flexible, with a large ecosystem of tools and custom monitors built up around Nagios."

"We have used this product now for quite some time and we are happy with it."

More Nagios Core pros

"NetFlow monitoring, real-time monitoring, and surveys have been the most valuable features for our business."

"The solution effectively monitors network devices and servers."

"The best feature of WhatsUp Gold is the automatic generation of topology and its integration with virtualization and wireless."

"It is easy to access and discover devices, as well as monitor them automatically. The topology discover is also a useful feature."

"The documentation is very good."

"In terms of pricing, I'd say that the pricing is nice and the product is good."

"The product is reasonably priced."

"The installation and configuration process are easy."

More WhatsUp Gold pros

Cons

"The alerting mechanism in Nagios Core could be improved."

"The dashboard should be improved."

"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."

"Nagios Core does not have a graphic display."

"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."

"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."

"The initial setup process could be easier."

"The tool needs to improve the integrations."

More Nagios Core cons

"The tool should focus on increasing its market share, as it is the only area of concern where improvements are needed."

"Pricing is too high relative to how many devices we use. The price list is not linear to number of devices."

"Users want SMS available via Whatsapp Gold. They don't want to go through third party SMS servers. The solution should work to make this possible."

"My understanding is that there are better products out there that do a better job."

"Integrations with other devices. I want to have a product that has full integration with my active directory so I can track user activity. I want to track my complete user activity, so I'm looking for a product to implement in the near future, which will have full integration with my network and active directory users. It became very difficult to track user activity."

"The pricing for this solution has gone up quite recently, which has led some of our customers to buy an alternative product."

"One of the biggest things that made us start to look at another product is we're not able to have an end to end monitoring from a user perspective throughout the system and back to the user. All the monitoring is from inside out, we need something that also can give us from outside in."

"The product is old and not updated."

More WhatsUp Gold cons

Pricing and Cost Advice

"Nagios Core is an open source solution, and there are no licensing fees."

"The product is cheaply priced."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"It's free."

"We are using the free version."

"We are using the open-source, unpaid version."

"We are using the free version of Nagios Core."

"The enterprise version has technical support. The version we are using is free."

More Nagios Core pricing and cost advice

"The price of WhatsUp Gold is good."

"The choice of version depends on the number of points, or devices, that you want to monitor, and this makes the product expensive."

"The pricing can be on the expensive side when considering competing products."

"The most valuable feature is the cost compared to other solutions."

"Pricing is reasonable compared to other products."

"This is a well priced solution."

"I'm not sure, but it's expensive. We don't pay any additional fees."

"It is per device, per year. The pricing is very clear. If you have a service agreement, you get all of your major upgrades and minor upgrades. It was under $10,000 to go all-in with all of the different add-ons for it."
