[OMCAGNT-2027]: Host name of the machine [] cannot be evaluated to Fully Qualified Domain Name (FQDN) format. Configure the host name of the machine to FQDN format. Add the fully qualified domain name in the /etc/hosts file (Unix) OR <Drive>:\Windows\System32\drivers\etc\hosts (Windows) and ensure that it maps to the correct name and IP address of the host. The recommended format is:
<ip> <fully_qualified_host_name> <short_host_name>
You can run the following commands on Unix to verify this:
$getent hosts 'hostname'
$host 'hostname'
For windows you can run the following command to verify this:
C:\ hostname
In the output, the fully qualified domain name must appear in the second field as specified in the /etc/hosts file
