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.

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

"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."

"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."

"The most valuable feature is the performance parameters of the system."

"The solution's most valuable feature is that it offers proper alerting capabilities."

"It is fairly easy to set up, and we can monitor pretty much everything we want to."

"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."

"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, and we primarily use it for user experience monitoring and determining which layer the problem happened to resolve it."

More Nagios Core pros

"The most valuable feature is the monitoring of resources."

"Their tech support is very good."

"The most valuable feature of WhatsUp Gold is NetFlow and the virtualized maps."

"You have to invest a few days to become an expert in this solution, but after that, it's possible to do almost anything with it."

"Auto scanning is most valuable. It looks for rogue devices on your network."

"The most important features of WhatsUp Gold are the server health and uptime it provides. Additionally, WhatsUp Gold is a Windows-based solution which is a benefit."

"The most valuable aspects of the solution are the application monitors that allow for discreet roaming on network devices."

"I use it on premises to monitor my network database. We monitor the link up/down and use the SNMP traps as well."

More WhatsUp Gold pros

Cons

"The core version is no match for the XI version."

"Generally, it does what I need it to do, but better error reporting would be great."

"The tool needs to improve the integrations."

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

"Application level monitoring is limited."

"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."

"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."

"It is a bit slow due to latency."

More Nagios Core cons

"The point system is not clear and clarity around this would improve our understanding of the system."

"The interface needs some work."

"You have to invest a few days to become an expert in this solution, but after that, it's possible to do almost anything with it."

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

"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."

"I think there are a few bugs now. Although they give some resolution for this, we cannot share the network remotely because of our company policy."

"I would like to see them do an enhancement to the application monitoring. A lot of other products do better application monitoring so they should do some improvements to the application monitoring."

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

"I would rate the solution's pricing an eight out of ten."

"It's free."

"We are using the free version."

"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."

"The product is cheaply priced."

"Lessening the price point would be an improvement."

More Nagios Core pricing and cost advice

"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."

"Pricing is reasonable compared to other products."

"The price of WhatsUp Gold is good."

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

"The tool's price is reasonable. WhatsUp Gold is cheaper than SolarWinds."

"There are some subscription charges that are quite heavy. I need to pay for support every year and these charges can be quite expensive. Aside from the initial cost for the tool, you need to pay additionally for support."

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

"This is a well priced solution."
