OMD 2.2.0 error render Grafana Graph to PNG

  • Hallo zusammen,


    ich kann, trotz erstelltem API-Key in Grafana, keine Graphen in PNG rendern.


    Im Grafana Log steht folgendes:


    Code
    1. t=2017-04-21T14:01:24+0200 lvl=info msg="PhantomRenderer::renderToPng url [http://localhost/prod/grafana/dashboard-solo/script/histou.js?host=kiho-srv-fs03&service=CPU%20Auslastung&theme=dark&annotations=true&from=1492747273212&to=1492776073213&panelId=1&width=1000&height=500]"

    Jemand eine Idee?
