Subject: [Observium] host_id in pollers table

Hi,

We have a image we have been deploying at remote sites for the poller.
This was a clone and added a new site and running into issues. Looking at the poller table I see the hostid in not different across some of the hosts, assuming his because we cloned the image.

What is this hostid referenced from? We made new SSH keys on each host but there must be something else this from and not really sure how to change it.

Thanks
