> unable to frame a host from input host: %[shost.my.domain.io](http://shost.my.domain.io)

@Andrew_Cholakian1 Thanks for your reply. I am using version 7.6.2 of Heartbeat. If you see the logs I quoted in this message you can see that the host is not empty. The logs are from the Docker container. In this example it is `host.my.domain.io` and if I change the `${PROM_HOST}` value the change reflects in the Docker logs. Please help. 🙂
