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

"It is an open-source platform with valuable features for performance and stability."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"The ROI is very good."
"You can save a lot of time using Nagios monitoring because otherwise you need to check all of your services or system one by one."
"Nagios XI is stable."
"It has a lot of flexibility for customization and a wide range of metrics."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"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."
"Its Docker Container concept is mind blowing. It is the first monitoring tool which comes with Docker features."
"The most valuable feature is the flexible discovery mechanism."
"Zenoss is more complex than LogicMonitor, but scalable and hugely customizable."
"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 the most flexible solution of this type, but it takes time to adapt."
"The product offers good documentation that helps with initial training."
 

Cons

"There's no convenient way to manage notes as the only way is to manage them through the database."
"They need more documentation for the plugins."
"The product does not have SAP monitoring."
"We are implementing our hybrid cloud strategy, and it will most likely not be suitable for monitoring our public cloud assets."
"Technical support is an area that needs improvement. It is not available 24/7."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"Initially, we encountered problems during the setup as some errors were noted due to a few prerequisites not being fulfilled and having some configuration files to edit and plugins to add."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"It would be ideal if the product offered sound alerts."
"This solution is complex for beginners so it takes some time to learn."
"The inclusion of a feature to show a graphical view of the network would be a helpful improvement."
"Now it is stable, but they should design threshold parameters in percentage instead of raw values."
"The AI aspect needs to improve."
"There was a problem with Zenoss and storage monitoring."
"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"
"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 an expensive solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"As it is not an agentless tool, I think it is expensive."
"Nagios XI is open source."
"The pricing is high with separate licensing for the product and support."
"We are using the free version of this solution."
"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."
"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."
"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."
"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."
