There are things like dashboards and reports (pre-configured and custom) that let me know that things are operating the way they should be, and when they are not.

Creating parsers to try make unknown events or currently unsupported devices produce meaningful information is extremely cumbersome.

The dashboards need to be improved. It gives you so much detail, but sometimes too much detail, especially to an executive, it's too much.

It lacks a "wizard" that shows a particular user's activity or particular circumstance. I think the interface is intimidating because there's so much information there.

If there is a configuration on the wrong side of the network or there are changes that result in harm to our IT infrastructure, the solution should immediately fix it.

Does not have load-sharing or high-availability, and these are important things to implement. I can do the same things in another way, but not naturally having these features makes it complicated.
