Currently when errors or warnings are displayed you have no direct clue when this has occurred. Some errors will stay in the monitor, even when the issue has been resolved.
No you have to check and in most cases need to conclude that it is an 'old' error/warning.

Currently when you are going to applications monitoring screen you have list of applications deployed, you then select one and then configure monitoring for receive locations, send ports and orchestrations.

It will be useful if you can a status a particular application is already monitored as part of xyz alarm. This will avoid people duplicating the efforts and also good overview of whether the applications (especially new ones) are monitored or not.

Would it be possible to built in an option when using the dates in saved queries to set default values, like 'today -1' or 'last 24 hours'?

Now when using a date, that will be of the moment when you saved the query, so you always have to adjust that.

When we need to filter in the ESB Exceptions screen we would like to use some additional fields, which are available in the screen.
Field we would like to have are;

Scope
Service name

The drop down box for selecting event sources is too small. When you wanted to do multiple selections it's not very obvious you need to hold the Ctrl key, and when you wanted to select something from top of the list and some from the bottom of the list it makes it extremely harder to configure.

You can instead have some kind of add/remove items between two list and make the drop down box slightly bigger so it's easy to scroll.
