Just a heads up... Upgraded to NPM 10.4 this weekend and while they were OK initially the historical interface graphs stopped updating after awhile. Polling was OK as I could get current stats via Report Writer and one of the graphs on the Interface Details Page used the old style chart and that graph was up to date. Did an edit on each of the problem charts and changed the Default Zoom Range from 2 hours to 1 hour and all was well. Have gone back in and set them back to 2 hours and again as of now all is well.
