Hi Scott -
Have you looked at the Report Management framework under the Registry Management
(System Management Portal -> HealthShare -> Registry Management)?
Both the "Management Report" definitions, and the "Patient Report" definitions are a good starting point for some things. (Take a look at /csp/docbook/DocBook.UI.Page.cls?KEY=HERPT_ch_management_creating#HERPT_C273872 in the docs of your HealthShare installation)
"Response times" can be a bit tricky, since this is a measurement that would be not something that happens at a single point in the system (i.e. multiple Access Gateways, each having their own "start/stop" events, but only their own)
