Odigos VM Agent is a PRO feature, and requires a license key which is read from /etc/odigos-vmagent/service.yaml. If you installed odigos with ODIGOS_ONPREM_LICENSE_KEY environment variable, the license key should already be set in the file. The yaml file should contain the following content: 
on_prem:
  token: "<your-license-key>"
To set or update the license key, edit the file and restart the service: 
systemctl restart odigos-vmagent
To verify that the license key is set correctly, check the service logs: 
journalctl -u odigos-vmagent
The following log message should be displayed if the license key is set correctly: 
INFO OnPrem token verified aud=<your-organization>
