How to change the week start day for the service quality and availability reports as our working days are from Sunday to Thursday?
How to produce a similar or almost a similar customizable service quality report for the respective teams e.g. application, infrastructure, etc.?
About first option, I don't know such functionality, about second I think you should extract metrics from dynatrace via script to elasticsearch and create reports in external tool like kibana/grafana.
Extracting metrics a paint unless you know what individual metrics you need for which entities, since Dynatrace will not provide "metric" export interface as it does for user sessions.
I'd rather recommend using the Dynatrace API directly and produce the reports in a business intelligence or reporting tool (Cognos / BIRT / Jasper reports / ... ).
