Hello community hopefully I'll find help. I installed icinga core, classic ui, idoutils, report and jasperreportserver via the quickstart dokus on the icinga website. Everything works fine I also added some host into my icinga master. I can connect to my JasperReportServer (tomcat) and can login. Under /root/icinga/datasource is the predefined ido datasource where I can test the Connection. It is working. But if I test a report under /root/icinga/reports/hosts and select one I can't select any hosts. There are none given. Where is the Problem? I can see hosts in my classic web gui of icinga e.g. localhost and one remotehost and everything is green. thanks in advance kind regards
