The link you posted just mention a way of access a DMI without authentication. What he asked was if there's a way to send a report to a shared directory in the network instead to an email ID.
If you have wget you could do the following:
wget --no-check-certificate "https://apm.gdn.demo.dynatrace.com:8082/LSSaveAs?format=pdf&lsEntryName=Applications&formatDiscover=direct&uid=NTk4RDhCQUVCMEJBNzUxM0U5OUE2QzBCQkE3RjA3NkU=" -O Applications.pdf
I hope it helps.
Btw. this command is not just some dummy example, it will actually work 🙂
Another idea: did you try to configure a task? Like described here:
We often use this for exporting data to a shared folder on a regular basis.
As far as I know sharepoint you can access the folders from the windows explorer as well (if it is configured).
The only disadvantage in this approach is, that the configuration files are only readed while service startup. Therefore if you want to change anything in the task you'll need a service restart.
