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

"Nagios is the best monitoring tool that I have ever worked on."
"This is a very good solution and it is simple to use, for any company."
"Nagios XI is stable."
"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."
"It is an open-source platform with valuable features for performance and stability."
"In my experience with Nagios, I've found that the most valuable features are the scalability and extensibility through using scripts."
"I can monitor a software made in-house to software of bigger companies."
"Our infrastructure is now under monitoring proactively and we don't have to wait for complaints from the customers or internal operation team to inform regarding any issue with the service."
"With this solution, they can have one million users at the same time with no crashes."
"It's easy to use."
"The custom built integration is one of the most valuable features because you can see all the especially critical items."
"It is very cost-effective compared to the tools I worked with in the past."
"The most valuable feature is the flexible discovery mechanism."
"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."
"Its Docker Container concept is mind blowing. It is the first monitoring tool which comes with Docker features."
"It is the most flexible solution of this type, but it takes time to adapt."
 

Cons

"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"While the UI is functional, I have always thought there was room for improvement here."
"The user interface needs improvement."
"The GUI could be improved."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"For some, it may be difficult to deploy."
"I feel that the maturity and user interface needs to be improved."
"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."
"The inclusion of a feature to show a graphical view of the network would be a helpful improvement."
"Technical support is 3/10, poor: Incomplete and poor documentation Undocumented processes Inconsistent solutions to problems depending on source"
"There was a problem with Zenoss and storage monitoring."
"Now it is stable, but they should design threshold parameters in percentage instead of raw values."
"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."
"This solution is complex for beginners so it takes some time to learn."
"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"
 

Pricing and Cost Advice

"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."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Licensing costs are reasonable."
"Nagios XI is an expensive solution."
"The pricing is high with separate licensing for the product and support."
"Nagios XI is open source."
"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."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
