Frédéric, You may need to enable the actuators https://apereo.github.io/cas/7.3.x/monitoring/Monitoring-Statistics.html To see configuration, select one of the actuators, then click on the button that looks like a book on a green background, then the configuration tab. The simplest setup is to enable all actuators (hopefully you have a dev or personal environment): Management: endpoints: access: default: UNRESTRICTED web: exposure: include: "*"
There are a lot of actuators (some from cas, some from spring). I am not sure which ones are required. On our servers that handle authn, all actuators, except for health, are turned off; a separate server, network accessible to only the ops team, handles Palantir.

Hi Ray, how do you make palantir work ? I can access /cas/palantir and see menus and tabs but no data at all ... I have this issue when trying to reload in the Applications tab : "Unable to contact the CAS server. Are you sure the server is reachable?" I have this dep in my build.gradle : implementation "org.apereo.cas:cas-server-support-palantir" (If there's any link with that : Account manager is turned on in cas properties and works) Do we have something to configure somewhere ?
