Hi,
IIUC, open your <JENKINS_URL>/api/xml?depth=2 to see the whole dashboard view in XML format, although it might be a bit tricky if you use nested folders though.
Regarding a particular job and it's historical build:
- <JENKINS_URL>/job/<job_name>/api/xml?depth=1 , it should provide the whole build history of a specific job name called <job_name> and the xml tag 'cause' should provide how it was built and also the user in case it was triggered manually.
Regarding the user information:
- <JENKINS_URL>/asynchPeople/api/xml?depth=1
There are some more details below:
