[sknep]

potential metrics:

• visits to [siteID]/builds/[buildID]/scans
• individually scan artifact (report) downloads
• relative time between build start date and report download
• relative time between build start date and view of the route at [siteID]/builds/[buildID]/scans
• How long it takes to run a scan and generate report
• Can a cost/scan be calculated
