Calculating issues across common components in several projects--possible?

[Tracy Miller]

I have 20 different and distinct projects but some of them share the same components.  I would like to be able to show data based on defects per component for example despite which project it is in.  Is this possible?  Even though I named the component the same in multiple projects, it appears as though it is a separate component and I cannot total it.  Is this true?

You can use the same name of a component and then use advanced filter to show issues across projects with JQL like "component = "name of your component".

Yes, this is true. Component is an object with properties. One of those properties is also "Name" and "ID" as the Name could be the same across the Jira, the ID will also be unique. So each and every component is different object. 

It is possible to resolve this via custom script on the server, but unfortunately I am not aware about any option on the Cloud. 

But definitely if will require little bit of scripting.
