Next move to setting the user limits, define the operations limit and bandwidth.

3. Although the module does not require any domain to work properly, you will need to use one to allow WHMCS metrics to be correctly fetched and displayed.
4. It is possible to verify if the usage statistics displayed in the product details are correctly calculated. Please run the below cron command in your console to do so:
php -q /home/yourWHMCS/modules/servers/VirtuozzoHybridInfrastructureS3/cron/cron.php metrics:fetch 

Remember to replace 'yourWHMCS' with the correct WHMCS directory.

5. You need to enable the statistics collection on your S3 gateway to allow the module to collect data and display them in the "Metric Statistics" in the admin area.
  • Create a file on every S3 storage node: /var/lib/ostor/local/gw.conf

 # Enable usage statistics collection.
