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 solution has a lot of plugins and scripts integrated with it."
"Nagios XI is stable."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"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."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."
"I can monitor a phone on a desk to very big servers of any company."
"I can monitor a software made in-house to software of bigger companies."
"It is very cost-effective compared to the tools I worked with in the past."
"The most valuable feature is the flexible discovery mechanism."
"Overall, it's a great solution, and I consider it to be one of the best."
"With this solution, they can have one million users at the same time with no crashes."
"It's easy to use."
"It is the most flexible solution of this type, but it takes time to adapt."
"Its Docker Container concept is mind blowing. It is the first monitoring tool which comes with Docker features."
"They have also accommodated many state-of-the-art technologies like Docker and ZooKeeper."
 

Cons

"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"We'd like to see more integration capabilities."
"The GUI could be improved."
"However, it is a bit complex and difficult for a first-time user."
"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"For some, it may be difficult to deploy."
"The user interface needs improvement."
"The AI aspect needs to improve."
"Now it is stable, but they should design threshold parameters in percentage instead of raw values."
"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"
"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."
"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."
"There was a problem with Zenoss and storage monitoring."
"Technical support is 3/10, poor: Incomplete and poor documentation Undocumented processes Inconsistent solutions to problems depending on source"
 

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."
"As it is not an agentless tool, I think it is expensive."
"The licensing fees for this solution are approximately $3,000 USD per year."
"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."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"Nagios XI is open source."
"Nagios XI is an expensive solution."
"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."
"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 depends on the customer, what he wants."
"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."
