The best thing about 5view is its easy to use interface. It's very simple to set up and configure. I like that it can be used in combination with other tools such as Nagios and Zabbix. I dislike that there are some features that are not available out of the box which requires additional licenses. For example, we wanted to monitor our mobile app but were unable to do so because we didn't have enough licenses. Also, we needed to install another agent in order to monitor our API. This was somewhat difficult for customers who are less technical. We solved this by providing a step-by-step tutorial on how to install the agents.
