Multiple third-party hosts deployed from the same image share an identical serial number, which prevents CloudMonitor from distinguishing between them. Delete the serial number on each affected host to fix this issue.
When the CloudMonitor plug-in is installed on a host deployed from an image, the plug-in automatically generates a serial_number to uniquely identify that host. Hosts deployed from the same image inherit the same serial_number, so CloudMonitor cannot distinguish between them.
To resolve this, delete the existing serial number on each affected host based on its operating system. The plug-in generates a new unique identifier the next time it starts.
