We are looking to generate some metrics/report on the following topics and would like to know where we can get the data/attributes from. Any help is appreciated. 

1. Average time to assign a case to a service desk agent - Per person per month
2. Average time to route a case to a resolver group - Per person per month
3. Number of cases processed per service desk agent - per month
