Quick setup and efficient automation boost IT consulting services
It would be beneficial if Atera implemented telephone support for general questions. When onboarding new clients and creating their portal, it would be helpful if presidents or company owners could see the current configuration progress step-by-step, rather than relying solely on email and ticket systems. The task system for technicians could be improved by adding recurring task capabilities. This would allow technicians to have checkmarks and task lists they can mark off as completed. While scalability meets growing needs, there haven't been many additions in the last two years. They are adding new features gradually, but there is always room for improvement.

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.
