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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Flowmon is more easy to understand and helps find network issues more quickly."
"The solution is stable."
"It is an open platform, so in terms of integration, we are quite happy. We can integrate it with other SNMP solutions. We can also integrate it with security solutions, such as a SIEM solution."
"Flowmon is more easy to understand and helps find network issues more quickly."
"The artificial intelligence and automatic detection system in Flowmon Solution are perfect for every, type of customer, such as government and commerce."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"The solution's most valuable feature is its simplicity."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"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 useful aspect of this solution is the ability to customize it for the client agent."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"The most valuable feature is the monitoring of processes."
"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."
 

Cons

"If there was better visualization in Flowmon Solution it would be good."
"It would be helpful to have more details about the monitoring of the infrastructure. It should have support for SNMP. This is something that is currently not there in the product."
"The licensing price could be better."
"I do not know the detailed pricing."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"The product's stability could be even better."
"The tool's AI model needs to be fixed."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"The product does not have SAP monitoring."
"We'd like to see more integration capabilities."
"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."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
 

Pricing and Cost Advice

"The price of the solution could be better."
"It works with a permanent license, and then you can pay for the support. For the gold support, you need to pay yearly."
"The licensing fee accrues only once, but that of support is annual."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"We are using the free version of this solution."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"Licensing costs are reasonable."
"As it is not an agentless tool, I think it is expensive."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
