I like Redgate Monitor's ability to bring metrics from multiple servers together in one easy to view window without complex set up of the dashboard. It's super easy to use when setting up alerting. I appreciate how I can quickly check VM disk usage, including predictions on when the disk may become full. The graphs for each database/server and the ability to group resources by function are very helpful. Overall, the dashboard is easy to view, and compared to the Azure portal, Redgate Monitor is generally easier and quicker to use. Review collected by and hosted on G2.com.
Currently the initial installation isn't the simplest. I initially had some issues setting up the correct network rules to allow it to connect to my VMs. This is now covered in the documentation for the product and not an issue. Review collected by and hosted on G2.com.
