For instance, we have a problem ticket for "XYZ Application crash."  Using Manage Engine's EventLog Analyzer tool, we send email triggers on certain events.  We would have a trigger that any time an application crash for XYZ is discovered, an email is sent to the service desk.  Each email would have a tag on the subject line that when received into the service desk it would automatically associate with the existing problem.

So, an email sent to the service desk with the subject line containing "XYZ" would create an incident and then be assigned to the problem.

We have 50+ email messages per day like this, and we want to see this frequency reflected in the total number of logged incident per problem so we can put our internal staffresources on the problems with the highest level of  occurrences.
