The links to Trends and Alert Histogram from hosts / services are 404ing.
Navigate to a host or a service. The links are in the top left corner under the object's information.
POTENTIAL FIX
The files to which these links go were removed in this PR.
Either the functionality was purposefully removed (which feels unlikely) and the links should be removed from the object pages or these files and any other files required for their functionality should be re-added. Perhaps with updated JS frameworks.
