UptimeMonster is an extremely useful tool for monitoring and managing websites and servers.
It allows you to monitor not only websites, but also servers by monitoring CPU/RAM/disk and network.
It monitors most protocols such as FTP / SSH / RDP / HTTPS / DNS / SMTP / POP3 / IMAP / UDP / TCP / ICMP and BL blacklists.
It also has a Status Page. You can work with collaborators

The solution has unique functionalities.

A particularly interesting functionality is the WordPress monitoring tool, including an activity log, site status check, plugin and theme management, site error log.

What needs to be improved to make the solution even better?

▪️ Special license for Appsumo
There is a bit of a problem with the special license that is offered here on Apsumo.

It is not entirely known how it will develop in the future, whether there will be new functionalities, whether they will be updated. There is a lot to explain here, but on the other hand I would not like to have a special plan either, just a normal plan offered by the developer, then I would feel much more at ease that I will not be left with some solution that will not be developed further, of which there were already examples on Appsumo that despite spending money, we were left with a solution, but which is still not developed and there is a big danger here.

▪️ Monitoring BL blacklists
Problems that I have encountered with monitoring BL blacklists:
It works a bit strangely, because I checked it in parallel on MX Toolbox and the system reports many incidents for one IP address, for one blacklist and does it every few minutes, once stating that it is on the list, and the second time together that it has been solved. At the time I check in MX Toolbox, I have no problems and it is a bit confusing and very frustrating when you get 50 notifications a day.
It would be useful to be able to disable checking of certain blacklists, because it is very annoying, so some more configuration is needed to adjust to user preferences.

▪️ The startup itself seems interesting and the solutions it has, but it would be useful to have better communication with users, respond to ideas, cooperate and constantly improve the solution, but in accordance with what users report, and not stick only to your own ideas.
