What are the best practices to create Azure pipeline dashboard. what is better to use workbook(KQL) or logs>query(KQL) to create dashboard?
Actually, both them are providing almost the same feature when creating a dashboard.
As far as I can remember, just in case you need to create a dashboard which needs a cross query(like query from 2 different azure log analytics), in workbooks you don't need to write query code for cross query since you can select more than 1 resources via UI, but in logs you need to write query code by using keyword like workspace for cross query.
So, in normal cases, you can just use the logs to create dashboard.
