Grafana with Graphite and Whisper


i have a icinga2 installation with graphite, whisper and grafana. In graphite i can see all performance data, but not in grafana. In grafana data source setting the “Data source ist working”. I have CentOS 7.6, Whisper 1.1.5, Graphite 1.1.5, and carbon 1.1.5. All packets are from pip install. Any ideas anyone?
