Meets the needs of the customer but all of the features need improvement
I do not choose the solution. The client does. I am an implementer. We are systems integrators. It is worth mentioning that the solution should be easy to install and offer the user exhibition capabilities. Also, a data sheet should be used to gather information about the product, to facilitate easy and simple implementation. I rate CA Unified Communications Monitor as a five out of ten.

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.

"This is a very good solution and it is simple to use, for any company."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails, and it also allows us to schedule downtime and maintenance."
"I really found Nagios a perfect fit for us and a good product to work with."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."

Cons

"All the features and functions of the solution can be improved."
"All the features and functions of the solution can be improved, specifically the user experience."
"The solution should have automatic baseline detection."
"The solution should have automatic baseline detection."
"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."
"It can be quite difficult to know which drivers and agents to use when setting up."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"The product's stability could be even better."

"While the UI is functional, I have always thought there was room for improvement here."

"The scalability of Nagios XI is scalable. However, it is not easy to do."

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