Monitoring plugin graph not showing

Hi,

I have installed Openfire 3.7.1 and its using OpenLDAP for user authentication . I also installed monitoring plugin 1.2 and i was using the embedded database and when i migrated to Postgresql then monitoring plugin doesnt show graphs . I removed Openfire and installed many times ,but monitoring graphs only works when i’m using the embedded database . Can anyone help me on fixing this issue or let me understand what requirments needed for monitoring plugins to work on with external database ?
