Struggled with complex licensing and limited support but have gained unified cloud monitoring

We face certain challenges with monitoring website uptime for our business operations because we don't have that 24/7 monitoring, so that's what we are working with ManageEngine on, regarding how effectively we can use that. I may not be able to give that information on how ManageEngine Site24x7 can be improved, but I felt that the monitoring or the licensing terms, such as the advanced monitors or monitors, are not very user-friendly. I feel that because I don't know how exactly we can check what devices use which license and how we can control those things; that's not user-friendly. For example, if I have to look at what all devices are utilizing my advanced monitor license or what all devices are using my basic monitor license, then if I want to pull a report or validate them, I don't have an easy option; it's too complicated.
