The official CMK Opsgenie Notification Script is using the “new” Opsgenie V2 API and all the Events are processd by the “Default API” Integration because they are not taken into account by the Opsgenie Checkmk Integration.
The Checkmk Opsgenie Integration is based on the old depricated Opsgenie V1 API.
Maybe that’s the Problem and Trieb29 needs to update the Checkmk Opsgenie Integration on the Opsgenie Website.
