I configure the time filters on my Dashboards and I can't to see all information on the charts.
I created a new dashboard but the result is the same.
Only I can to see 1 hour on the chart.
*I recently migrate to Dynatrace 6.5, (my last version was 6.1)
If you have only 1hr of data in charts it means it's comming from the live session in server memory and you have no connection to your DB. Check your connection and repository logs and server logs for issues.
