To successfully implement continuous delivery, it would be very good to have more detailed information on performance changes of my builds/stages/jobs.

On the build level i'd like to see the following numbers:

• average duration of an individual stage during a certain period of time
• fastest execution of an individual stage during a certain period of time
• slowest execution of an individual stage during a certain period of time
• average waiting time before an individual stage started during a certain period of time
• shortest waiting time before an individual stage started during a certain period of time
• longest waiting time before an individual stage started during a certain period of time

On the stage level i'd like to see the following numbers:

• average duration of an individual job during a certain period of time
• fastest execution of an individual job during a certain period of time
• slowest execution of an individual job during a certain period of time

On the job level i'd like to see the following numbers:

• average duration of an individual task during a certain period of time
• fastest execution of an individual task during a certain period of time
• slowest execution of an individual task during a certain period of time
