Something I miss from our old RMM provider is the ability to have a dashboard program. In short, this program scrolled through the systems and customers and we could see at a glance the systems that needed attention. The devices were colour coded with green being no problems, amber being minor problems (updates required etc) and red being major problems (critical updates, low disk space etc). This made it easier to identify problems and act faster.
Currently in the ITarian/Comodo One portal, you have to manually go through each device to see the exact problems or use the dashboard feature, but even the dashboard isn’t 100% clear where problems may be. Automated emails are nice (which we use), but again, having that glance dashboard really made the difference.
