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

"The technical support is good."
"This solution has improved our ability to determine the source of a connection failure in our network, and now we are able to monitor the service provider's router and make that determination."
"The overall performance of the product is superb."
"It is an open-source platform with valuable features for performance and stability."
"The ROI is very good."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"The solution's most valuable feature is its simplicity."
"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."
"Its Docker Container concept is mind blowing. It is the first monitoring tool which comes with Docker features."
"It's easy to use."
"With this solution, they can have one million users at the same time with no crashes."
"Overall, it's a great solution, and I consider it to be one of the best."
"The product offers good documentation that helps with initial training."
"The most valuable feature is the flexible discovery mechanism."
"It is the most flexible solution of this type, but it takes time to adapt."
"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."
 

Cons

"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"Its simple deployment but complexity comes once you have to import more plugins."
"However, it is a bit complex and difficult for a first-time user."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"Nagios XI can improve its GUI for users with a new look."
"Business services monitoring is still really basic."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"The inclusion of a feature to show a graphical view of the network would be a helpful improvement."
"The AI aspect needs to improve."
"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"
"There was a problem with Zenoss and storage monitoring."
"This solution is complex for beginners so it takes some time to learn."
"It would be ideal if the product offered sound alerts."
"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."
"Technical support is 3/10, poor: Incomplete and poor documentation Undocumented processes Inconsistent solutions to problems depending on source"
 

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."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"Nagios XI is an expensive solution."
"The licensing fees for this solution are approximately $3,000 USD per year."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"Licensing costs are reasonable."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"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."
"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."
"It depends on the customer, what he wants."
"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."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
