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

"This is a very good solution and it is simple to use, for any company."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"The most valuable feature is the monitoring of processes."
"The dashboard allows you to see what's going on in the overall system."
"The custom built integration is one of the most valuable features because you can see all the especially critical items."
"They have also accommodated many state-of-the-art technologies like Docker and ZooKeeper."
"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."
"The most valuable feature is the flexible discovery mechanism."
"The product offers good documentation that helps with initial training."
"Its Docker Container concept is mind blowing. It is the first monitoring tool which comes with Docker features."
"It's easy to use."
 

Cons

"The GUI could be improved."
"The product's stability could be even better."
"Open-source software is usually not user-friendly."
"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 reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"The product does not have SAP monitoring."
"The inclusion of a feature to show a graphical view of the network would be a helpful improvement."
"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."
"The AI aspect needs to improve."
"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."
"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

"The pricing is high with separate licensing for the product and support."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios XI is an expensive solution."
"We are using the free version of this solution."
"Nagios XI is open source."
"As it is not an agentless tool, I think it is expensive."
"Licensing costs are reasonable."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"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 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."

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