Send automatic reports about services in Warning state

Hey everyone,

I’d like to know whether it’s possible to send weekly, monthly, … reports about devices who have a service in a Warning state.

Specifically, we applied an uptime service to all Windows servers and created a servicegroup for said service. The service checks how much time has passed since the last restart of the server. For the servicegroup, our DC department would like to receive a monthly automatic report about the devices in a Warning state. I know that we can manually export the info as PDF, CSV, etc. through the Overview, but if possible we’d like to receive it automatically.
We do have the Reporting module installed in version 0.9.2, but I haven’t been able to apply a report which meets my requirements. We’re also using Icinga Web 2.8.2.

Thanks in advance and have a nice day!
