Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Generates close to real-time alerts so users can resolve issues, but needs more integration and public cloud monitoring features
As Zenoss Service Dynamics is more for network-centric devices and you want to monitor, for example, a server, its services, IP addresses, and interfaces, if it's a network and you're going to monitor multiple items, you'll be charged multiple times. This is what Zenoss Service Dynamics needs to improve to make sure that customers pay just one fee to monitor the entire server. What I'd like to see in Zenoss Service Dynamics in the future is a public cloud monitoring feature, particularly for the Azure public cloud. Another additional feature I'd like to see in the next release of the solution is integration with the Azure public cloud because I know that there are some services from Azure that Zenoss Service Dynamics is currently unable to monitor.

Quotes from Members

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

Pros

"If you are a mid-sied company with an eye on expansion, this solution is very good."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."
"We love Nagios XI due to the fact that JPS Web is very useful."
"I really found Nagios a perfect fit for us and a good product to work with."
"The product allows comprehensive monitoring of your environment, from basic monitoring of your servers health to more complex tasks like AD, database, and, to some extent, application-level monitoring."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements, it is flexible and easy to integrate with our systems, and you can customize the solution by adding additional features using code."
"In my view this product is very good value for money when compared with other commercially provided monitoring solutions."
"Its Docker Container concept is mind blowing. It is the first monitoring tool which comes with Docker features."
"Zenoss is more complex than LogicMonitor, but scalable and hugely customizable."
"What I like most about Zenoss Service Dynamics is that it monitors the devices and gives close to real-time alerts. For example, in case the device is not available, Zenoss Service Dynamics generates an alert so my team can resolve the issue."
"It's easy to use."
"It is very cost-effective compared to the tools I worked with in the past."
"With this solution, they can have one million users at the same time with no crashes."
"It is the most flexible solution of this type, but it takes time to adapt."
"The most valuable feature is the flexible discovery mechanism."
 

Cons

"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"Technical support is an area that needs improvement. It is not available 24/7."
"I feel that the maturity and user interface needs to be improved."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"WebUI should be improved (visual aspect) and should incorporate non-relational databases."
"I think that the community needs to concentrate development to get a standard GUI (Adagios is a side project) and gives the user a better notification system."
"The installation can get very difficult depending on what Linux flavour you are using."
"As it is open-source, it is not user-friendly. Open-source software is usually not user-friendly."
"The inclusion of a feature to show a graphical view of the network would be a helpful improvement."
"There is room for improvement with the administrative part. They introduced Control Center to manage things in Zenoss 5. The services that Zenoss provides remained the same, but the administrative part, since they introduced Docker, etc., has become a little complex"
"As Zenoss Service Dynamics is more for network-centric devices and you want to monitor, for example, a server, its services, IP addresses, and interfaces, if it's a network and you're going to monitor multiple items, you'll be charged multiple times. This is what Zenoss Service Dynamics needs to improve to make sure that customers pay just one fee to monitor the entire server. What I'd like to see in Zenoss Service Dynamics in the future is a public cloud monitoring feature, particularly for the Azure public cloud. Another additional feature I'd like to see in the next release of the solution is integration with the Azure public cloud because I know that there are some services from Azure that Zenoss Service Dynamics is currently unable to monitor."
"It would be ideal if the product offered sound alerts."
"Technical support is 3/10, poor: Incomplete and poor documentation Undocumented processes Inconsistent solutions to problems depending on source"
"The AI aspect needs to improve."
"Now it is stable, but they should design threshold parameters in percentage instead of raw values."
"This solution is complex for beginners so it takes some time to learn."
 

Pricing and Cost Advice

"Nagios XI is open source."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"The licensing fees for this solution are approximately $3,000 USD per year."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"The pricing is high with separate licensing for the product and support."
"We are using the free version of this solution."
"As it is not an agentless tool, I think it is expensive."
"The pricing depends on the environment, the number of services, and the size of the data center. It can go from $100,000 to a million dollars."
"It is very cost-effective compared to the tools I worked with in the past. The company is gaining a lot with respect to the cost factor. It provides agentless monitoring and in a very cheap way."
"It depends on the customer, what he wants."
"There are additional costs you'll have to pay apart from the license fee for Zenoss Service Dynamics. I can't remember exactly how much my company is paying because I don't handle the finance part, but the cost is paid annually. On a scale of one to five, with one being the cheapest and five being the most expensive, I'm rating the solution three out of five."
