Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.
ClaudiaChen - PeerSpot reviewer
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 ability to set up templates and groups of checks, as well as customize the checks themselves."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"It's great for monitoring IT services infrastructure."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"The solution's most valuable feature is its simplicity."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails. It also allows us to schedule downtime and maintenance."
"It is an open-source platform with valuable features for performance and stability."
"The custom built integration is one of the most valuable features because you can see all the especially critical items."
"The most valuable feature is the flexible discovery mechanism."
"They have also accommodated many state-of-the-art technologies like Docker and ZooKeeper."
"Its Docker Container concept is mind blowing. It is the first monitoring tool which comes with Docker features."
"The product offers good documentation that helps with initial training."
"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."
"It's easy to use."
 

Cons

"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"The Configuration Wizard needs improvement, because not all vendors are present."
"The tool's AI model needs to be fixed."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"The interface could be more user-friendly."
"It can be quite difficult to know which drivers and agents to use when setting up."
"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."
"We'd like to see more integration capabilities."
"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 was a problem with Zenoss and storage monitoring."
"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."
"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"
 

Pricing and Cost Advice

"The pricing is high with separate licensing for the product and support."
"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."
"Nagios XI is open source."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"Nagios XI is an expensive solution."
"Licensing costs are reasonable."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"It depends on the customer, what he wants."
