LonLee Greetings!
Is there any way for administrator to compile a report to see how many users have been using the Azure OpenAI services which we have configured?
If you are authenticating the users, you can log these metrics in your code.
Also, to monitor the usage of your Azure OpenAI service, you can use Azure Monitor. Azure Monitor collects usage data and provides metrics that you can use to analyze the usage of your service. You can analyze metrics for Azure OpenAI by opening Metrics under Monitoring section.
I would suggest you, please check Monitoring Azure OpenAI Service for more details.
