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.

Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.
