[from support case 01340786 ]
Although this is not something we support as UIM product, the UMP portal is hosted in a liferay site.
Liferay supports integration with google analytics, so you can try to set this up by following the liferay instructions:
https://dev.liferay.com/discover/portal/-/knowledge_base/6-1/liferay-monitoring-using-google-analytics
For the liferay site you are interested to report, as described in the liferay instructions above, go to the control panel and access the "site Settings" Then > Advanced (on the right) > Analytics
"Put your Google Analytics ID (which should have been provided to you when you signed up for the service) in the field and click Save. All the pages in the community you selected will now have the Google Analytics code in them and will be tracked"
Please take into account this is not a procedure that we support, so if you have any issue this may need to be resolved engaging liferay communities.
