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.

Quotes from Members

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

Pros

"We use the solution to meet the needs of the customer."
"Good end-to-end monitoring"
"For us, it's very key to know the voice quality of the total solution, which is based on many components across many domains."
"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."
"Nagios is an open source monitoring tool for monitoring network services, with easy installation, a user-friendly and configurable interface, and the ability to monitor disk space, CPU utilization, memory usage, host availability, NFS availability and many other things, making it widely used in IT markets."
"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."
"An excellent solution that is easy and intuitive to implement."
"I really found Nagios a perfect fit for us and a good product to work with."
"Nagios is the best monitoring tool that I have ever worked on."
"Nagios XI is stable."
"The most useful aspect of this solution is the ability to customize it for the client agent."
 

Cons

"All the features and functions of the solution can be improved, specifically the user experience."
"The solution should have automatic baseline detection."
"Nagios provides most of the features by default, however to add more services to it, it requires additional plugins which require little effort on administrative end."
"We are implementing our hybrid cloud strategy, and it will most likely not be suitable for monitoring our public cloud assets."
"The product's stability could be even better."
"The tool's AI model needs to be fixed."
"The installation can get very difficult depending on what Linux flavour you are using."
"This solution would be improved with the inclusion of additional services. Monitoring streaming services is an example of something that is not currently supported, so in order to handle this, I would have to write a script."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"Technical support is very good but is very expensive. It is becoming more and more expensive just like the upgrade."
 

Pricing and Cost Advice

Information not available
"The licensing fees for this solution are approximately $3,000 USD per year."

"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."

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